New King of Compacts, October 10, 2009
I bought this camera on 10/9, which is the first day it was available here in Kansas City. I have already taken a couple hundred shots with it comparing images side by side with my G10 at various settings. This review is of my initial impression based on the short time that I have had it. I was anxiously awaiting the release of this camera. I own a Nikon D90 DSLR, but there are many times when I prefer to just take a compact. In the past the Canon G10 has served that purpose, but the S90 boasts improved low-light performance and smaller size.
The first thing I wanted to test was image quality and noise at high ISO settings. Most photography hobbyists and pros know that low light performance is the number one factor influencing camera and lens prices. This is the main reason an f/2.8 zoom lens costs 3-5 times as much as an f/3.5-5.6 zoom. The S90 performs superbly in this regard. RAW images from the S90 set at ISO 800 were equal to or better than RAW images from the G10 set at ISO400. Both luminance and chrominance noise were lower in the S90 images. This represents a 1 stop improvement, which is what I was hoping for. These comparisons were made with all noise reduction disabled in camera and in the DPP software. I tested all other ISOs and found the S90 to be better at all ISO settings above 100 and the 2 cameras demonstrated equal IQ at the base ISOs of 80 and 100.
Canon also boasts about the S90 having a faster f/2.0 lens compared to the f/2.8 on the G10, but this part of the camera did not impress me. The lens only has the 1 stop advantage at the absolute widest setting and the max aperture closes down fast from there. The G10/G11 lens is faster at the telephoto end and the difference is negligible at all zoom settings in between. Both lenses are equally sharp throughout their zoom ranges.
The ergonomics of the camera will take me a while to get used to. I was looking for a smaller camera and the S90 definitely fits the bill. But now that I am using it, I wonder if it might be too small. I hope that it will become more comfortable in my hands as I get used to it. On the G10, I could operate all of the controls on the right-rear of the camera with the thumb of the hand holding the camera. With the S90 there are fewer controls that I can operate one-handed and at times I feel like I might drop this camera, because I just can't get a good grip on it. Other ergonomic concerns are that the rear control ring turns too easily and I have found myself unintentionally adjusting settings because of this, which was never a problem on the G10. I think I might miss the external ISO and Exposure Compensation dials on the G10, but I have set the front control ring to adjust the ISO setting and I would honestly need to use it more before I say the controls are not easy to access; again this should improve with more use. None of the concerns I have about the size and controls on the camera would dissuade me from the purchase; the trade-off is worth it for the smaller carrying size and improved performance.
The camera ships with a newer version (3.7) of Canon's Digital Photo Professional software. There is not much difference compared to older versions, but there is one nice improvement: the lens aberration section is enabled for images taken with the S90. This allows for correction of vignetting, CA and distortion. I do not understand why the same controls are not available for RAW files taken with the G10. There is still no straighten function in the software, which is a disappointment. Another disappointing factor about the software is that Canon has not yet released a new RAW Codec; the current version (1.5) does not support the S90 or G11. This allows raw files to be viewed in Windows and for thumbnail images to be created in Windows explorer. I am sure they are working on an update, but I wish they had this ready by the time the camera was released.
I went step-by-step through the menus and features of both cameras during my comparison and most functions are very similar. The S90 has fewer AF options and no remote control, but I do not think I will miss either of these.
I considered giving this camera only 4 stars because of the couple of hits I mentioned above, but then decided that would not be fair. The title of "Best Compact" has been debated feverishly on the web, with most votes going to the G10 and LX3. But now, I think Canon's new release of both the S90 and G11 will put a quick end to these debates. There is no question in my mind that this pair sits above all competitors. Therefore a five star rating is the only logical choice. I highly recommend this camera.

My Powershot S90 Has Arrived, and It's Fantastic!, August 29, 2009
Early Impressions
I was delighted to have finally received my Powershot S90, and without further adieu, let me say that this is one heck of a camera. It's not perfect -- you can take truly terrible pictures with it just like you can take terrible pictures with a D700 -- but when used properly, the camera turns out remarkable shots that make us find it hard to accept the images are coming from a camera that fits in your pants pocket.
What struck me first upon using it? First, it's size. This thing is small, and it's light, too. It's a bit smaller than my Panasonic TZ3 and TZ5, and it's lighter, too. (The camera uses a front and back metal construction with plastic on the top and bottom, but the Panasonic's, while also using metal, use a thicker gauge steel which adds a feel of sturdiness but also adds some weight, as well). The camera also has a high-quality feel to it. The buttons click and depress well (although the rear wheel is a bit too easy to turn, in my opinion). It has a rounded shape, so it feels comfortable in the hands, and when you stick it in your pocket, it will slide right in and out without snagging. The screen on this thing is simply gorgeous: why can't every camera have a screen like this? It's large, bright, and pretty high in resolution (461,000 pixels). You can't help but admire the camera's design once you get looking at it and using it.
Next, the camera seems to perform well in terms of speed and overall operational use. The screen has the typical lag when taking shots, but you can adjust this somewhat in the menu system to speed things up, and quite frankly, every small camera I've ever owned exhibits this behavior. It is easy to use most of the camera's functions, and you may have heard about the programmable control ring around the lens on the front of the camera. It's operation is easy, solid (the ring "clicks" with detents at different positions), and, to boot, there is the standard programmable "S" button that the Powershots "S" cameras have typically had.
But of course, I'm interested in high ISO operation, and so I immediately took it into the livingroom where it was quite dark, and just started shooting. I was quite surprised at the results. You are not going to necessarily submit these to win any contests, but for the most part, the camera took nice shots even in that bad shooting environment, and the vast majority of the photos came out quite well (I will post a few with this review). The camera is the first (along with the Powershot G11) to deploy Sony's new ICX685CQZ sensor, a 9.31mm diagonal sensor with high performance specifications. With a little post processing, many of them look quite good. As the ISO crept into the very high ranges (800 and above) some sensor noise became apparent, but this is certainly the best low-light performance I've seen in a non-DSLR so far. (See my explanations, below, to see why this is possible). Surprisingly, some shots as high as 1600 ISO seemed to be acceptable as long as you are not a "pixel peeper." I was quite surprised when I discovered that a few of the shots had been taken at this high ISO 1600 level -- I've never had this experience before with a point and shoot camera.
Outdoor operation is fantastic. My outdoor shots for the most part have come out very well, with rich color, great detail, and little sensor noise. Like most Canon portables, these images seem to respond well to post-processing (you can sharpen them quite easily, and Canon now uses a standard meta-data tagging format that is readable by virtually all photo editor programs.) I even turned the EV down -2/3 while outside, and the sensitivity of the camera is so good that, even with this reduction in EV, my shots came out sharp and clear. Again, I will post a few shots with this review.
The camera TRULY excels at macro photography. The macro shots I've taken thus far are clear, sharp, and have great depth of field. In a word, they are superb: this camera is a macro shooter's delight. (A nice touch, too, is that in AUTO mode the camera automatically shifts into macro mode, without having to press any buttons!) The functionality just begs us to keep shooting macros over and over again. I've been able to take macro shots that I only dreamed of before, and the camera makes it easy to do so.
And although this is not an objective measure, the camera is just plain fun to use. It works smoothly, is light, has a beautiful screen, and seems to keep cranking out one nice shot after another. Wow.
Early Pro's and Cons
-- PROS --
1. Exceptionally small and lightweight (100 x 58 x 31 mm and 175 g)
2. Increased sensor size for a portable with a lower megapixel count (Sony's new ICX685CQZ sensor, 9.31mm diagonal)
3. Reasonably large zoom factor (28-105mm, approximately 3.8X zoom)
4. Wide end is very wide for landscape shots, vistas, group photos (28mm)
5. Fast f/2 lens permits high levels of light passage in low light situations
6. f/2 lens makes shallow depth of field shots incredibly effective - this camera is a macro shooter's delight
7. Two types of highly effective shake reduction technologies
8. Design makes lens cap unnecessary
9. Extremely high image quality for a pocket sized camera
10. HUGE 3 inch LCD screen with 461,000 pixel resolution and 100% coverage of the shot you wish to take
11. RAW mode allows for highest image quality and post processing
12. Virtually every camera setting is user adjustable (ISO, shutter speed, aperture, EV, white balance, etc.)
13. Ring-based control implementation one of the best on ANY current camera
14. Reasonable cost for a camera of this ability (but watch the prices climb as the camera stays in and out of stock)
16. Metadata being properly written to the file so they can be read by photo editing software (a problem with earlier Canons and some other brands)
17. SDHC flash card is highly standardized, and is coming in larger and faster formats (necessary if you are taking many RAW shots)
18. Extremely attractive physical design
19. High quality construction apparent on first use
20. Reasonably good battery life - most people are reporting about 300 shots (without flash) between charges
-- CONS --
1. Zoom ends at 108mm (3.8X zoom), which may be a deal breaker for some
2. Does not take HD videos (but does shoot 640 x 480 at full 30fps)
3. LCD screen not at the highest current resolution as seen in some DSLR's (but is great, anyway)
4. Proprietary battery is an expensive proposition, as two or three are needed for daylong trips
5. Camera case not included, and is expensive to purchase afterword
6. No prices below retail due to the high demand of the device
7. May be difficult to initially acquire due to high demand
8. Still no "universal standard" RAW mode file format - the camera manufacturers need to address this soon!
9. Mechanical noise when setting focus and moving between bright and dimply lit areas - this is the aperture being adjusted, but it can be annoying
Some Other Things I Can Tell You about this Camera (and the Powershot Line in general)
Canon's reinstatement of the venerable "S" series within the Powershot line is a welcome move to thousands of photographic enthusiasts. Although the S90 announcement a few months ago caught the photographic community by surprise, the announcement was greeted with overwhelmingly positive reactions. As a person who had been greatly impressed by my older Powershot S80, a phenomenal camera for its time and a pleasure to use, I was one of them.
Read the online posts of virtually any photography forum, and you'll quickly see there is no shortage of individuals, many of them longtime professional photographers, who have tired of carrying around anywhere from four to ten pounds of photographic equipment simply to get a few shots while out on a trip. (I think it may have been Scott Kelby who said, and I paraphrase, "The best shot is the one you take," and if the weight and size of your equipment makes it so that you end up not bringing your camera with you, you won't take any photos at all! This is a corollary to one famous photographer`s statement that there is an inverse relationship between the amount of photos you take and the amount of equipment you bring.) The problem has generally been, however, that the smaller you make the camera, the worse the image quality of the photos the device can produce. This has set up a tradeoff between image quality and camera size, and, more specially, image quality and sensor size, which for years has forced photographers to take a stand with one side of the equation or the other, and then defend to the community why they made such a choice.
Without going into too much detail here, the problem in manufacturing a compact camera that takes excellent images under a wide range of environments essentially boils down to the sensor, the electronic device that takes the place of film in older cameras. The larger the sensor, the more surface area for light to fall, and the higher the density of the sensor (in megapixels) the higher the sensor's resolution. Camera manufacturers have excelled at developing ever higher densities in sensors of the same physical dimensions -- many 12 and 14 mexapixel cameras are using sensors sized no larger than those on previous cameras possessing only 3 or 4 mexapixels -- but where they have fallen flat on their faces is in the development of sensors that have good resolution AND low noise. And the most direct impact of increasing mexapixel count on a sensor that remains static in size is the increase of electronic "noise" (also known as the "signal to noise...

4.0 out of 5 stars
Lightweight, low profile compact with great low light capability, October 22, 2009
Canon S90 IS is one of Canon high-end / advanced Canon Powershot compact camera. Its unique characteristics are slim, low profile body with great noise control in high ISO plus 28-105mm f/2-f/4.9 bright zoom lens. The other advantage is the camera is very pocket able. It fits in your jeans' pocket.
IMAGE QUALITY AND ISO
Canon S90 IS has 1/1.7 sensor size which is slighty smaller compare to its main competitor, Panasonic LX3 (1/1.63"). From my test, S90 IS image quality is very good across focal length but dynamic range (the difference between the brightest and darkest parts of an image) is limited . This is also a problem most of digital camera out there, but S90 is slightly worse compared to competitors.
However, regarding noise control and handling, S90 IS is excellent. The new algorithm works very well to reduce or erase most (if not all) chroma-noises which degrade image quality significantly. Image shot at ISO 1600 is very usable for regular print and web.
BODY & HANDLING
Canon S90 IS has a slim, low profile look, so it is very good for street photography. It does not attract attention like digital SLR camera.
For control, it has two main dials, both of them are round. One is located in the lens, and the back of the camera. The back dials also function as four way buttons. This design is similar to Samsung WB1000 design.
Front ring dial can be customized for several options: adjust aperture/shutter speed, ISO, exposure compensation, manual focus, white balance or zoom. The front dial is not like zoom barrel in the lens, it is not smooth, instead, it has several stops point. There will be a "click" sound to let you know if you hit the stop.
I usually use the lens dial to zoom. There are five stops in the dial: 28mm, 35mm, 50mm, 85mm and 105mm. All of them are popular focal lengths. I found this is much better way to zoom rather than traditional way (pull a lever on the shutter). It is faster, less noise and accurate. It is great for learning how focal length affect perspective and distortion too.
Mode dial is harder to change because they have put some resistant to it. It is to prevent accidental switch.
There is also a shortcut dial which you can customized to many function such as AF servo, intelligent contrast, face detection and many more.
Canon S90 has 3 4:3 ratio LCD screen with 460k resolution. It is similar to Panasonic LX3, but better than typical compact camera. It is worse than Samsung WB1000 which has AMOLED screen (over 1 million resolution).
However, build quality is not up to par with leading advanced cameras such as Canon G11 and Panasonic LX3. It made by metal but it feels plasticky. I have a sweaty hand and it registers my fingerprint! Also because of its flat design, there is no place to secure your grip. But overall ergonomic is not bad.
OPERATION & AUTO FOCUS
Start up and turn off time is fast. It only takes around 1.5 seconds for each. Compare to LX3: around 1.75 seconds, Ricoh GRD3 : 2 seconds respectively. Auto focus is typical compact., around .75 second, will take more time if you point to low contrast subject. Camera operation is very fast and very responsive upon instruction.
COMPETITORS
Panasonic DMC-LX3K 10.1MP Digital Camera with 2.5x Wide Angle MEGA Optical Image Stabilized Zoom (Black)
Panasonic LX3 is an arch-rival of Canon S90 IS. It shares same concept of bright and wide zoom lens. However, there are many differences between the two such as the focal length, build quality, image quality and handling, please read Panasonic LX3 vs Canon S90 IS for complete comparison.
Samsung TL320 12MP Digital Camera with 5x Schneider Wide Angle Dual Image Stabilized Zoom and 3.0 inch OLED Screen (Black)
Samsung best advanced camera is similar with S90 in one way, they are both compact and has great handling. Samsung WB1000 has AMOLED LCD screen which is a lot clearer, Samsung also has wider and longer zoom. However, Canon S90 IS is better in low light condition.
Canon PowerShot G11 10MP Digital Camera with 5x Wide Angle Optical Stabilized Zoom and 2.8-inch articulating LCD
G11 is a big brother to Canon S90 IS, it has superior control and body handling, but it is much bigger in size.
CONCLUSION
Canon S90 IS is a great choice for photographer who like a lightweight, pocket able compact but doesn't want to skim on image quality and control. It has very good operational speed and have some great customizable options. I especially like the zoom ring dial on the lens, which has Digital SLR like control. S90 IS is also superior in low light situation. However, Canon S90 Is also has a downside, such as below average build quality (relative to competitors) and limited dynamic range.
Subjective rating compared to other advanced compacts in 2009
* Image quality 4/5
* Body handling 4/5
* Performance 5/5
* Features 3/5
* Value 5/5
