When the Kx arrived, K7 owners who were more than content with their current bodies coveted the superior high-ISO (low light performance) capability of the Kx. At least I did. And while the K7 was a capable tool, I often found myself compensating for its weaknesses (which were limited to high ISO and autofocus continuous (AF.C) performance). Not so with the K5.
I won't go into the specifications since those can be found elsewhere but I'll give my overall impression - what I like and what could be better:
+ Great ergonomics. Love the compact, solid body which is identical to the K7 save for a heightened knob and elongated AF lever. I was even able to use the same split prism focus screen I had purchased for the K7.
+ Fantastic high-ISO performance - clean and offering far more flexibility than the K7. I'd try never to breach ISO 800 on the K7 whereas the K5 is routinely pushed past ISO 3200. While I wouldn't give it equal footing to a full frame camera, it's arguably the best APS-C out there in this application.
+ Outstanding dynamic range -- shoot in RAW and leave your graduated ND filters at home.
-+ Improved auto-focus, especially AF-C compared to the K7, but not quite on par with either the D300s or 7D in AF-C.
+ User-friendly, easy to navigate menu system - white balance adjustments are a breeze.
+ Good WB and JPEGs "out of the box"
-+ Yes, 1080p video but at 25FPS vs. 24 -- surely a firmware update in the future
- Audio records at 32KHz sample rate
- Only has a single SD/SDHC slot - would prefer dual with Compact Flash
- Limited to 1/180 X-Sync speed - but this is ample in most scenarios
- Images shot in portrait don't autorotate on playback - but did on the K7(?) - again, a likely firmware update
+ Blissful near-silent shutter
+ Compatibility with all those great manual K-mount lenses of yore.
Although I'm a long time Pentax user, I considered and evaluated both the Canon 7D and Nikon D300s without bias. While both are outstanding DSLRs, I preferred the Pentax K5.
An all-around excellent camera and a joy to use. A noteworthy upgrade.
on April 19, 2011
I've shot with the K-5 for a month now, and I'd like to share my viewpoints on it.
First, the noise level in the high-ISO images really is as excellent as the technical reviews say it is. This means that you can use a higher ISO number and get results equivalent to other cameras at lower ISO numbers. You can take your shot with either a faster shutter time (better motion freezing) or smaller aperture (better sharpness, etc) or just enjoy the reduced noise. This puts the camera at an advantage over all other APS-C cameras and a few of the full frame cameras.
Next, the movie mode is a mixed bag. It has the 1920x1080 at 25fps setting, as well as 1280x720 at 30fps settings, and lower settings too. The 25fps setting is often quoted as a major problem, with videographers wanting to shoot 23.976fps as a "cinema" mode, but it takes only a bit of video conversion to change the frame rate to 23.976 and resample the 32k s/s stereo signal to match. So, if you're desperate you can manage, but even then it is clear that this is not a camera for someone who wants video as a major use. The biggest problem is the inability to autofocus while shooting. The worst-case test of this is shooting a 2-year old running around in a house. Being indoors with available light, the aperture is open and depth of field is short; as soon as the child runs towards you the focus is way out. The camera is simply not usable in this kind of situation. On the other hand, with available light and a subject which is not in wild motion, the results are acceptable, but even then, a much less expensive camcorder often gives superior results. The only place where the K-5 shines in video is if you are outdoors, and you have a 500mm telephoto mounted, and you want video of distant wildlife - then, you have a system giving nice results. However, again, if you want a camera with great video capability and very good but not quite great still capability, go for the Panasonic-DMC-GH2.
Next, color gradient linearity. A partly subjective criteria, not an easy item to quantify, but not too hard for a professional photographer to see. This is the quality of a color image which makes it as lifelike and genuine-looking in the shadows and highlights as in the midranges. A face is a good choice, especially a baby's face - a fair skinned baby should have subtle colorations in the midranges perceivable because their skin is so thin it is nearly transparent. The shadows should look like skin in shadow, not various types of dirty brown, and the highlights should look like brightly illuminated skin not just brightly-colored areas. Being able to set the K-5 with 14-bit linearity may be the key to its terrific color gradient linearity. The K-5 has a wonderfully realistic treatment of living things, and subtle colors which extend from bright to dark look authentic in a way which the eye can see but which are hard to describe - to put a phrase on it, the beauty of the image is deep. The genuineness of the color gradients give a realistic sense of depth which stay in the image even after you have blown it up and put it on your wall. Again, this is hard to quantify, but you won't see this much in the Panasonic GH-2. Or even the Canon Rebel 550D. Pentax has gotten this just so right. I've seen Nikon D7000 shots with similar qualities, but I'd have to still give the K-5 the advantage here. To me, this is one of the deciding features of the K-5, and it has nothing to do with all the technical tests at which it has excelled.
Let me say a few words about the image stabilization, which unlike most cameras is in the camera body. You can put any lens on the camera, including old classics, and get modern image stabilization. If you try this with Canon, you will end up stuck on your tripod. Why don't other manufacturers do this? And yes, it works extremely well. Even for long lenses.
Now, auto-focus. I have to say, when shooting a still subject the K-5 is near perfection. It is fast and positive in bright light, slower but certain in fairly dim light. If it fails to find a focus in autofocus mode, it will not acknowledge the shutter press. The focus-assist LED is excellent and works well for darkened rooms, but only for distances less than about 5 feet, above that it gets a little less reliable. I sometimes take flash shots in absolute darkness of subjects over 5 feet away, and I've gotten good results using a small hand held flashlight to get a temporary focus, then hold it and turn off the flashlight, and take the shot. This gives you the ability to get dramatic shots like an animal in water at night, splashing, with every drop suspended in air. On the other hand - the situation with a baby running around in circles in front of you, the test I gave for the video mode focus problem, remains a worst case. Moving to continuous focus mode, you get excellent sharp shots, but the timing may be awkward - for instance, with the child running in circles, I got many shots at the point the child turned to run away, when I wanted to get the shot a half second earlier. But enough shots were sharp and well-timed to make it a good experience. Doing the same test with the Canon 550D gave an advantage to the Canon's AI-Servo mode focus, which seemed to follow the child much better - but in many cases, the shot, when taken, was not as well focused as the K-5. So summing up the results for the Canon 550D, I got better autofocus speed, but inferior accuracy. Both cameras can give good results, but the photographer needs to know each camera's weaknesses.
I ordered my K-5 from Amazon Warehouse Deals a month ago, and quickly noticed that the front setting wheel was defective. You could turn it and it would sometimes ignore you, other times skip values, so that in manual mode, where you need both the forward and rear wheels, it was difficult to use. As days passed the problem got worse, so I sent the camera back to Amazon (thanks to their excellent return policy). Being an engineer myself, I recognized it as an optoelectronic component failure, not a design issue, so I felt confident that a replacement would not have the problem again, and this did not bias me against the K-5. While waiting for my refund, I spent the time carefully looking at my photos and thinking whether any other camera would better fit my needs. The cameras which came the closest were the Panasonic Lumix GH-2 and the Nikon D7000. But I couldn't avoid coming to the same conclusion. I reordered the K-5 because of its low noise level, wonderful color linearity, unique in-camera image stabilization, rugged weather sealing, and compatibility with the excellent Pentax Limited lenses. To me it was well worth the extra money, because no other camera has these same features.

I upgraded from the K-7. K-5 keeps the excellent design, unparralleled build quality, super quiet shutter sound and outstanding ergonomics of K-7, has the best APS-C sensor. High ISO performance is stunning. What worth mentioning is that the Low ISO performance is also outstanding, noticably better than the K-7. Also, the super high Dynamic Range is very helpful. AF speed is not much improved, but much more decisive. For DA* SDM lenses, the speed is not improved at all. All my lenses are SDM, but I find the speeds are fast enough. The AF-C mode is much improved, but can be improved further. The camera is fun to use, I bet everybody who has a K-5 loves it.
I'd like to comment on the following two problems:
1. stained sensor problem was solved already, all cameras having serial number larger than 3973*** are fine. Basically this problem is now worry free.
2. The bad Auto Focus under artificial light condition. I believe this is a relatively unusual problem that happens on a few bodies. Don't be afraid about this, just buy one and try it at home. If it does happen (very little chance), then exchange for a new one.
I have hand-on experience of Canon 7D and Nikon D7000, I would say the D7000's image quality (from ISO100 to ISO3200) is on par with K-5, both of which are better than the 7D. 7D's build quality is on par with the K-5 but K-5 is much smaller, D7000 falls behind in this regard.
I highly recommend the K-5.

I had to replace my Pentax K20d, which I liked a lot, because of a thief who broke into my car. I really wouldn't have considered spending the money to upgrade to the K5 without this prodding, but although I would gladly consign the thief to jail, I admit to feeling like I wound up winning with the new K5! This camera is so much more of an upgrade to the K20d than I expected.
First, the CCD sensor is getting a lot of praise for its high ISO capabilities, which was one of the K20d weaknesses. I would do everything that I could to avoid going beyond ISO 800 on the K20, but I have taken shots at 6400 on the K5 that easily rival 800 on the K20d! Why is this important? Because I can shoot in low light conditions that I couldn't have even imagined trying with the K20d. A lens that was marginal in low light now becomes remarkably useful, so a wider range of lenses can be considered, including some lower priced lenses that I might have skipped over because they were not fast enough. A definite win!
Then there is the output quality. I really liked the K20d, but the color saturation seemed a bit dull at times and needed to be pushed either in camera or via software later. Not so with the K5 and using the same lens. Colors are crisper and more vibrant, which means less tweaking needed later.
On the K20d, I found the 'Live View' function to be of very limited use. But with the resolution of the 3" screen on the camera and the ease of switching into Live View with just a push of a button, I use Live View routinely. Want to shoot with the camera held above your head? Touch the live view button and do it!
Others have commented on the focusing improvement and I can confirm that with the same lens, the focus seems a bit faster but more importantly, hunts far less and locks onto targets the first time almost all of the time. Focusing in low light is remarkably improved. So shots that I may have missed before are more likely to be captured.
I really loved how the K20d felt in my hand so I was a bit worried that the K5 would be a letdown since it is smaller, but the K5 feels solid and yet comfortable because of the grip ergonomics and the textured finish. I recently picked up a used Pentax 60-250mm lens that is over 6"long and 2 1/2 lbs, but while it is a heavy combo, it feels balanced and is remarkably comfortable for such a big lens. It is easy to hold the K5 in one hand and reach all of the important functions. With the 60-250mm lens you would definitely want to use two hands after a while - the lens is great but it definitely adds a lot of weight - but taking one handed shots is possible because of the ergonomics of the K5, especially with the in-camera stabilization function.
Speaking of the anti-shake function, there are pros and cons to in-camera vs. in-lens stabilization, but I have to say that I prefer the in-camera version for three key reasons: First, every lens you mount on the camera becomes a stabilized lens; second, non-stabilized lenses are less expensive to purchase than stabilized lenses, and third, a stabilized lens more rapidly uses the battery charge than the in-camera stabilization because you are moving glass lens elements instead of a light CCD sensor. So while you cannot see the stabilization working via the viewfinder, I will sacrifice this slight advantage for better battery life, cheaper lens cost and always-available stabilization regardless of the lens you are using!
There is so much more I love about the K5, but I will highlight just one more thing. The menu system on the K20d was kludgy and a bit hard to work with. The menu on the k5 is much cleaner and easier to use. I can find what I am looking for more easily (and there is a ton of stuff you can do in the menus!)and making adjustments is fast and sure. More importantly, the things I use the most are directly accessed by the wealth of buttons on the camera, but for those occasions where I need to use a menu the K5 is a definite step up. And just for the fun of it, here are a few things in the menus that you can do, many of which you cannot do with the 'big name' brands:
* Fine tune focus adjustment for each lens you own. I checked and my 60-250 front focused just a little bit, but with about 20 minutes of work (using Live View), I was able to adjust this myself and lock in that adjustment for that particular lens. Mount another lens and this adjustment does not apply because the setting is saved as lens specific!
* In camera HDR capability, even hand held, lens correction (based upon the specific lens you are using!), dynamic range enhancement, etc.! (I haven't played with much of this yet, but there are some good comments on this on Pentax forums. And just the ability to have this at your fingertips gives you a lot more creativity to play with.)
* Shooting sports today and landscapes tomorrow? You can set up the camera to 'favor' speed or depth of field. Or you can set the camera to use the MTF scores of the specific lens mounted to the camera to keep the lens in its sweet spot for best performance (assuming you are using a Pentax DA lens). And you can set the range you allow the Auto ISO function to use AND how rapidly it adjusts to higher ISOs.
The K5 seems a bit pricy to some, but considering all of the above plus the weatherized body (and complete system when you use either the kit lens or another lens like the 60-250mm) and you would have to spend a ton more to get a truly competitive camera. The real decision, in my mind, is whether you are stuck on buying another brand because of their name or you already own a lot of their lenses. I can understand buying a 'Canikon' if you have an investment in lenses already, but if you are buying a 'Canikon' just because of the name on the camera strap, DON'T! Give the K5 a try and you will not be disappointed!

I just got my k-5, and it is pretty much exactly what I was looking for. I upgraded from the k20d, in the k-5 surpasses that excellent camera in every respect.
The AF is so much faster than previous pentax models. It can still struggle sometimes in very low light when pointed at low contrast area, but so does pretty much any camera ever made. Liveview AF if very fast as well, even faster with the new 1.02 firmware.
The dynamic range is astounding, and equals or beats pretty much any digital camera up to this point (and probably equals the exposure latitude of negative film). I can pretty much dispense with multiple exposures for HDR, because i can now just expose for the highlights and then bring the shadows up in photoshop with almost no added noise. This is probably the most revolutionary feature.
High ISO is fantastic, getting pretty close to the performance of the best FF cameras of the current generation. It is at least 2 stops better than my k20d, and probably closer to 3 when you factor in that you pretty much cant make it produce banding noise at any iso, which makes the files much easier to clean up. I can use iso 6400 at A3 size and it looks great, just a quick pass with noise ninja or topaz. The ISO performance of this camera was unimaginable a few years ago when talking about aps-c sensors.
The build quality is awesome, and it just feels great in the hand (i have average sized hands). Its very compact for a camera in this class (compared to nikon d300s. canon 7d, etc..), but is very solid feeling due to the magnesium alloy shell and steel frame. It is fully weather sealed and very rugged. Try doing this with any other camera besides the olympus e-5 [...] . It somehow manages to squeeze a remarkable number of manual controls in without feeling cramped.
Ergonomics is a particular strong point for Pentax in general, and specifically the k-5 is probably the best pentax yet camera in this regard. All the major controls fall easily under your fingers, with no need to take your eye away to change aperture, shutter speed, iso, metering pattern, af mode, etc.. The great high iso performance makes the pentax TAV mode truly useful finally (lets you set aperture and shutter speed, and changes the iso to get proper exposure within your set auto iso range). More than any other company it seems like the pentax engineers are also photographers, and everything is laid out in a way that is logical and well conceived. Also there is the pentax unique hyper program and hyper manual modes. Hyper program lets you easily switch from your set program mode to AV or SV mode by just turning the control wheel of each. Turn the back wheel and you are in aperture priority, turn the front and you are in shutter priority, hit the green button and you are back to your program mode. In manual mode you can make your adjustments to shutter and aperture, and the green button will take a meter reading and make an exposure suggestion for you, which quickly gets you in the ballpark. Its great.
The shutter/mirror sound is whisper quite, a very nice change from the loud thwack of my k20d. When i shoot with my flash, the flashbulb pop is the loudest sound coming from the camera. Its very refined and unobtrusive. The max continuous speed is an impressive 7 frames per second, and mine can go for an equally impressive 25 frames before the buffer fills. This is all pretty much class leading.
This camera pairs exceptionally well with the tiny Limited primes, making it possible to have exceptional IQ with very small size, yet retaining all the control of a pro camera. Street photographers should seriously consider this combo.
I can recommend this camera to anyone without reservation. It is the best camera I have ever used, and it makes the other cameras in its class feel gigantic and clunky.
14 stops of DR
Clean High ISO, usable ISO 6400
Compact, rugged build
Great color, tonal gradations
AF tracking not that great, but pretty good for all but the most demanding circumstances.
Needs high quality lenses to shine, but why put crap glass on a camera like this anyway?

This is quite simple the best camera I've ever owned. It takes great photos and is very well built. I wasn't going to upgrade yet. I'm the type to wait until a new electronics product has been out for a while and dropped in price, but the reports I've seen about this camera triggered my choice to take a chance.
The first thing I noticed is how petite the K-5 looks, though looks are deceiving. This baby is dense and weighs much more than you'd expect from the size. I'm sure that the magnesium body and extensive weather seals have a lot to do with that. This is one solid piece of kit. The camera has plenty of external controls, about what you'd expect from a body in this price range. I've shot with my sealed K20D in the Pacific Northwest rain a lot with no problems. My two shoots with the K-5 in the wet show it to be as least as good. Though Pentax has dropped the multiple exposure button. You can program the custom program button to duplicate that feature. As far a programming, the K-5 has the extensive customizability I came to love with my K20D. The feature list is extensive and way too long to go over in a short review.
And the photos! This camera has a huge dynamic range, over 14 stops! Even at ISO 800 it has the same exposure range of my K20D at 100 ISO. The tonality you can get from a print is beautiful. Another nice feature is the ability to choose 14 bit as opposed to 12 bit RAW files. It's a small thing but brings the camera in line with Nikon's offerings. I can't comment on the many shooting modes and effects available. They only apply to JPEG images. I don't understand why anyone would buy a camera this costly and capable and throw away so much potential image quality by shooting JPEG. That's not to say that the JPEGs from the K-5 aren't perfectly fine. They are. It's just that RAW files from this camera hold so much more information than a JPEG can. And that information translates into a very real difference in what you can print if you take the time and care to. My experience seems to mirror the incredible sensor abilities that DXO Labs has published for the K-5.
One other huge advance is the focus speed. This is the fastest and most accurately focusing camera Pentax has ever built, easily in line with Canon and Nikon's offerings in the price range. One small disappointment is that the fast focus and 7 fps capture rate makes the camera suitable for sports and wildlife photography, but the camera has a somewhat limited buffer. The 40 frames of JPEG is reasonable but the 15 image RAW buffer is a bit cramped. But then Pentax doesn't make the long lenses for that kind of photography anyway. Though Sigma does make some with Pentax mounts. With the few ballgame or bird photos I take, I haven't found the buffer limit to be a problem.
Looking at my histograms shows that the K-5 has a tendency to underexpose about a third of a stop. That's really no problem as I've pulled usable photos out of totally black portions of the initial image, great reason to shoot RAW. Another is the great low ISO capability of the K-5. the quality of my 6400 ISO photos is slightly better than what I get with the K20D at 1600 ISO, easily 2 1/2-3 stops improvement depending on situation. And the camera focuses much faster in low light, too.
If I were a video shooter I might find a problem with the lack of autofocus in video mode. The newest Canon and Nikon cameras have that ability, though the autofocus is slow on both during video capture. That's the nature of phase detection focusing that true DSLRs use in Live View or Video. The couple of videos I've shot look great. It's enough for me. And the camera does allow for an external microphone.
It was commented that this review is to impersonal and that I use terms that people don't understand. To make this more clear:
14 stops of DR means in the real world is that my photos look better than any I've ever taken. Color gradations are smoother and more subtle. It means that I'm able to pull usable details out of parts of the image that I would have given up on before because they were too dark. It means that I can take single shots in situations where before I would have used HDR or exposure blending to pull in detail in both bright and dark areas of a scene. It means that I can the same tonal range at ISO 800 that I get with a K20D at ISO 100. It means that this is a terrific camera. I guess I'm a bit excited that a Pentax camera finally gets great press. I'm a bit tired of having equipment that I very much like ignored by most photographers.

The K-5 is really something special. I tried our Nikon, Cannon, and Sony before landing on a K-5. Now granted, Nikon, Cannon and Sony all make great cameras - so I am not going to go into a fanboy war between all the brands - I'll just focus on why I chose the K-5, even though it is about 2 year old technology at the moment (May 2012)
Feel - The K-5 is solid, rock solid. It feels like it could survive the Zombie Apocalypse, and we'll need someone taking photos - right? In all seriousness, this is a tight, weather sealed camera that is built like a tank. It is also much smaller than most DSLRs out there - almost compact (well for a DSLR) It just feels good in the hand and is an absolute pleasure to take photos with. Some have compared it to Leica Ms - but I won't go that far - however, this is a great DSLR for street photography - you wont' be scaring your subject away, especially if you use one of the Pentax wonderful limited primes (the 40mm looks like there is not even a lens in the camera)
Image quality - this baby just takes great pictures. The 16.3 MP sensor is a Sony and it produces great results. Low light performance is very good. Frankly, I don't blow up my shots to life size, so I don't need 24 or 36 MP - more megapixels does not always equate to better photos - that is really up to the photographer. When paired up with a quality lens - the images a stunning. When paired up with an ok lens (kit lenses) - the images are pretty darn good.
Lens selection - some will argue that Nikon and Cannon just offer more lenses - and that is correct. They offer A LOT of lenses, most of which, honestly, you will never use. Pentax offers a great number of lenses and have these absolutely amazing limited primes that exude quality. They are awesome and make the experience just all that much better while giving you wonderful image quality.
But it's Pentax! - Pentax is a quirky company and they have been going through a lot of issues. With the recent acquisition of Pentax by Ricoh, I think the future is bright. And Pentax really focuses (no pun intended) on the photographic experience. Yeah - they may be the underdog, but I can tell you I get just as good, if not better, images with the K-5 and some of the prime lenses than my colleagues with their expensive and heavy Canikon gear.
All in all - this is a great value DSLR. There are better out there - but I have yet to find one that has the feel of the K-5. Cameras are very subjective - so your opinion may vary.

This is an excellent camera that, like all quality tools, steps completely out of my way and lets me experience pure photography with quality results and minimal hassle.
I've been shooting with the K-5 for a little over 6 months now and have taken over 10,000 photos with it. I think I'm in now a good position to share my impressions of the camera.
- Very responsive with excellent ergonomics. Every mode is well thought out and it's easy to quickly change settings in a given mode with only my right hand and no visual cues.
- The sensor is amazing. Excellent high ISO performance, excellent low ISO performance, excellent dynamic range. Very low noise.
- Large collection of older, optically-excellent lenses available second-hand. The build quality of many of these lenses is much higher than you will find today (outside of the pro market). You often lose auto-focus or other features, but a competent shooter can get amazing output and they are fun to shoot with!
- In-body stabilization gives these older lenses image stabilization!
- Excellent prime and zooms available for fair prices. I recommend checking out the Pentax 50mm 1.4 prime, and the Tamron 17-50mm 2.8 zoom as a start.
- The compact, magnesium alloy body gives an immediate (and lasting) impression of quality.
- Weather sealed body, which can be combined with a WR lens for a great outdoor kit.
- Has a full compliment of high-end modes and features
Could Be Better:
- The video mode is high-quality, but basic. Only Motion JPEG is offered, the camera will not refocus automatically, no dedicated video button.
- The availability of high-quality lenses that support quiet SDM focusing is limited.
- Some excellent 300m lenses are available, such as the Pentax 300mm f/4 prime, but not as many as Nikon or Canon
- No current Pentax offerings over 300m, you'll have to go third party or used and this is not the ideal system for those extreme focal lengths.
For my particular situation, nothing in the "could be better" category is relevant to my needs. There is no camera currently available for under $2,500 that I would trade my K-5 for.
Image quality is amazing.
AF system still lacking, albeit improved *UPDATE: Download the 1.03 Firmware and reset your camera to fix low light front focus *
This camera is what the K-7 should have been 1.5 years ago. This is a superb Pentax, definitely the best APS-C Pentax to date. However, I can't help feel that the camera is overpriced, even though the image quality does make it almost worth the asking price alone. Again, if this camera were released 1.5 years ago instead of the K-7, I would have given it 5 stars. The market has changed since then.
The first thing I did with the camera was shoot a fund raising gala in a moderately lit banquet hall. The first thing I noticed is how little improvement there was in focus for this situation. The lenses were still slow to lock on and had trouble with the differing light (Sigma 30mm f/1.4, SMCP FA 77 f/1.8, and SMCP 60-250mm f/4). The flash exposure was about the same as the K-7 (P-TTL doesn't work well for bounce flash at any sort of distance), so the first thing I did was change the flash to "A" mode (auto thyristor where the flash sets exposure) and got much better results.
When I reviewed the pictures I was shocked at how noise free they were. Even the ISO 6400 shot from the 60-250mm was relatively clean, probably about like ISO 1600 on my K-7. I could even recover underexposed ISO 1600 shots, something I would never dream of doing on the K-7.
The shutter is like the K-7, and it might even be quieter. Definitely the quietest APS-C sensor camera I have used (quieter than a D300s or 7d), and also refined feeling. Not the squeaky sounding shutter in some of the older Pentax's.
The next thing I noticed when shooting in bright high contrast situations was how much purple fringing it shows. Doing side by side comparisons between it and my K-7, I noticed the K-7 was relatively purple fringe free, where this camera fringed quite noticeably. Think the difference between the K10d and K20d (K20d had almost no purple fringing where K10d had a lot). This shouldn't be a deal breaker for most, but be aware of it. Proper RAW developing can take care of much of it.
This is certainly the best Pentax to date. The image quality is amazing, the feature set of the K-5 is excellent, and the camera is certainly a step up. If it is worth the asking price is a decision each individual has to make. I think with a better AF system it would easily be worth the asking price.

Well, there doesn't seem to be a whole lot that I can add to all the reviews already submitted. This is a great tool, no wait, maybe a better word would be to describe the Pentax K-5 is that it is a WEAPON. Why do I say that? Mainly because you can take it in the toughest environments, and it can tackle any of them, and have you looking like the hero in whatever photo assignment you find yourself in.
I have been shooting professionally since the days of film when film was king. I have used what are considered top of the line cameras in my career in both the film and digital age. After a period of semi-retirement from the photography business, I decided to give this Pentax K-5 a try. Wow, what a camera. It is packed with several ways to customize it for your shooting taste and tendencies. It is as solid as they get, very easy to handle (I do use the battery grip that you can get for it) and have used it in the rain with a weather resistant lens, and it just keeps going; producing great results. You can buy a Canon or a Nikon and pay more but not gain any real huge advantage over the Pentax K-5. Sure you can get one that will shoot at a higher frame rate, but for most, the ability to shoot a seven frames per second is more than adequate. You can also, maybe, choose a Nikon or Canon for higher ISO capability, but honestly, the noise level at higher ISO's is very good and on par with the competition.
I currently use four lenses with the Pentax K-5: Pentax DA 18-135mm WR f3.5-5.6 lens (a nice sharp, all around lens), Pentax FA 50mm f/1.4 lens (I use this lens quite a bit, beautiful bokeh, great portrait lens), Pentax DA 35mm f2.4 lens (Very inexpensive, but surprisingly sharp with good contrast and color rendition), and finally, the Pentax DA 14mm f/2.8 lens (it amazing how close up you can focus on something with this lens. It helps you get some real neat perspectives on the subject your shooting). What is great about Pentax is that you can use any k-mount lens with this camera, so the possibilities seem endless.
Do I recommend this camera, you betcha. What is even better is that it is affordable. So if you want to spend a lot dough so you can be in the status quo, go ahead, but it won't make you a better photographer. But if you think of the camera as a tool, or as I call the Pentax K-5, a weapon, then when you learn how to use it for what it was intended for (a camera for taking great moments in time), the Pentax K-5 then becomes a mighty weapon in the hand indeed.
