BODY & HANDLING
Pentax Kx weights 581g, and its dimension is 122 x 92 x 69 mm. It is one of the smallest DSLR camera around, but not the lightest because of body material and 4X AA batteries.
Using batteries has been always been debated, some people like to have lithium battery with their camera, especially those who does not or concern about reliability of rechargeable batteries. Some might prefer the universal AA batteries because they are available everywhere and the rechargeable one is relatively cheaper compare to lithium one.
Built quality of this camera is generally good for beginner digital SLR, sturdy and substantial. Ergonomic is not the best especially for people that has big hand or finger, but it is good in general.
Like KM, the camera interface has been simplified yet very accessible. It has one thumb dial which you will use this a lot to change setting values. There are dedicated trash button, AF/AE-L, exposure compensation button, customizabe green button, live view button, info button, four way buttons which are shared with ISO, WB, Flash, self timer. These are basically what you will need and expect from a good digital SLR camera.
There is also a shooting mode dial, where you can find manual and semi automatic control. There are also some popular scenes mode and video mode. Unique to Pentax, there is Sv (sensitivity mode), which allow you to set preferred ISO and let the camera decide on aperture and shutter speed value.
Changing setting is fast and easy because of availability of many dedicated buttons. Main LCD screen could be activated by turning the camera to ON position or pressing INFO button. Pressing INFO button twice, you will get 12 squares representing popular settings such as auto HDR, image size, shake reduction, etc.
This small control panel is a great help and better than Nikon's info screen, but it is not better than Olympus super control panel.
LCD SCREEN & VIEWFINDER
LCD screen is basic, plain 2.7" , 230k. Compared to recent years DSLR, this screen is a bit outdated but it is not bad. Viewfinder is relatively big compare to beginner DSLR camera. Only Canon 500d and 450D can match the size of the viewfinder.
AUTO FOCUS PERFORMANCE
Auto focus (used with 18-55 kit lens) is surprisingly fast in bright light or low light situation. You will get AF confirmation in the viewfinder (hexagonal green dot) but there is no indicator where the active focus point is. For who that rely on automatic 5 points, 11 points or central point AF, it might not be a problem, but for those who usually use other individual AF point, it might be a bit of inconvenience.
IMAGE QUALITY AND ISO
Pentax Kx images in natural setting are not bright and saturated like competitor like Canon DSLR, but they are more muted and a bit cold. It is similar to Nikon DSLR such as Nikon D90. Nikon and Pentax Kx uses Sony sensor, and that might explain the similarity.
But don't too worry if you don't like muted color, because you can always set higher saturation in Pentax custom setting or deal with it later in your favorite photo editing program. But off course it won't match Canon color when you both set the saturation setting to the max.
The sensor strength is on high ISO setting. It matches Nikon D90 and even slightly better. Combined with built in shake reduction, this camera is very good in low light photography such as night scene or indoor performance. This performance might be the best for crop sensor camera up to date and only to be beaten by expensive full frame camera such as Nikon D700 12.1MP Digital SLR Camera (Body Only) or Canon EOS 5D Mark II 21.1MP Full Frame CMOS Digital SLR Camera (Body Only)
OTHER FACTS & FINDINGS
* Pentax Kx is available in 100 colors combination in Japan
* Built-in photo processing like auto HDR is slow (takes approx. 10 sec to process and to make a good HDR, you need tripod). It also drain batteries power quickly. Live view, movie recording is very basic for DSLR standard and it also drain batteries. Prepare plenty of rechargeable AA batteries if you keen on using these features.
* The kit lens 18-55mm is generally an OK kit lens, but to get better image quality especially sharpness and image acuity, I recommend you to look for some better lenses such as Pentax 16-45 f4 or 17-70mm f4.
Canon EOS Rebel T1i 15.1 MP CMOS Digital SLR Camera with 3-Inch LCD and EF-S 18-55mm f/3.5-5.6 IS Lens Price: $750
is a leading beginner cameras with 3" hi-res LCD and 15 megapixel image resolution. The most important maybe the access to Canon extensive lenses. But this camera is more expensive and slower in continuous burst (only 3.5 fps), no built-in image stabilization, and image is not as clean as Pentax Kx' image in high ISO setting.
Nikon D5000 12.3 MP DX Digital SLR Camera with 18-55mm f/3.5-5.6G VR Lens and 2.7-inch Vari-angle LCD Price: $700
D5000 is also a great low light performer like its brother Nikon D90, but the problem with this camera is lack of built-in auto focus motor. This limit your lens selection. There is no built-in image stabilization either. Like Canon and Pentax beginner DSLR cameras, D5000 has live view and movie mode, plus swivel screen.
Olympus Evolt E620 12.3MP Live MOS Digital SLR Camera with Image Stabilization and 2.7 inch Swivel LCD w/ 14-42mm f/3.5-5.6 Zuiko Lens Price: $700
The E-620 is very small and compact because of smaller image sensor (which is actually a disadvantage). E-620 has swivel LCD screen and built-in image stabilization. Click the camera name for review.
Pentax Kx is a small wonder. It is great camera for low light condition, very portable (especially combined with Pentax pancake lenses), and the design is very user-friendly. It has two problems that prevent this camera to be the perfect beginner/enthusiasts camera: the active auto focus indicator is absent , and battery life is short when you use photo retouching features and record movie often. However, with the current price point, this camera gives you a better value than its competitors.

AF performance is significantly improved. Even though I did not really feel that it was much faster, focus is dead on even in very poor light. There is no difference in AF speed for SDM lenses. Some people reported that they sometimes had problems with the K-x / Tamron 17-50 combination, I have yet seen that. I have to say that improvement in AF alone is enough to justify the upgrade for anyone with a Pentax older than K20.
Noise performance is another area that K-x just left K10 in the dust. When both were set to ISO200 and at 400% magnification, darker areas remained smooth for K-x while the K10 was visibly noisy. With the limited experience at ISO6400, I am so far very pleased with K-x noise performance.
I like a real optical view finder but I love LV for macro. I don't have any problem with the penta-mirror viewfinder. It might be a tad darker but you will hardly notice.
Some people have reported that K-x has a larger dynamic range than K10; however, I cannot confirm that yet. I am hoping that this is indeed the case. It is safe to say that it is at least as good as K10.
Before I placed the order, I was actually quite concerned with the lack of AF point indicators in the viewfinder. I think I am OK with this arrangement. It is obviously not as easy as K10 but not a deal breaker. As for the lack of a 2nd e-dial, it is again not a deal breaker since I also have a Ds which does not have a 2nd e-dial either. Weather sealing, not a deal breaker. I cannot justify spending another $500 just to get these features.
There are plenty of significant improvements over the K10 to make K-x a keeper. There are just a few minor issues.
Shutter/mirror is just as noisy as K10. I prefer the K7 but cannot justify the price difference. Again, it is not a deal breaker.
I have relatively large hands and hope that someone will market a battery grip for K-x. I have a battery grip for K10.
In summary, I can confirm the findings of many published reviews. It is a very capable camera and perhaps the best value in its market segment. It certainly took sales away from K7 but I think Pentax will increase market share at the expense of competition. BTW, it is also the cheaper dSLR in my collection. Great job Pentax.
