Given the success of Canon's highly acclaimed G Series, it's no surprise that ambitious photographers have been eagerly anticipating the next model in its evolution. The wait has paid off handsomely with the introduction of the PowerShot G9. In image quality and functionality, the G9 stands above the competition with 12.1 megapixels of resolution, 6x optical zoom with Optical Image Stabilizer, and RAW mode for the ultimate in creative control. Sophisticated design and high-quality construction complement the technology and make the G9 a camera to be reckoned with.

Big Impact in a Compact Package
The PowerShot powerhouse: A class-leading 12.1-megapixel digital camera with unique Canon DIGIC III Image Processor, 6x optical zoom, and Optical Image Stabilizer.

12.1-megapixel resolution gives you plenty of rich, deep detail to work with. Blow up images to poster size, or enlarge and crop any section without fear of pixilation.

With DIGIC III, your images boast superior quality, the camera operates at top efficiency and battery life is enhanced. What's more, DIGIC III enables Canon's Face Detection Technology and red-eye correction to give you better, more true-to-life people shots. Simply press the Shutter Button halfway down, and the camera automatically pinpoints the faces in the scene and chooses the ideal focus point. The camera controls exposure settings and flash to keep every face looking bright and natural. Red eyes can be corrected during playback.

iSAPS Technology is an entirely original scene-recognition technology developed for digital cameras by Canon. Using an internal database of thousands of different photos, iSAPS works with the fast DIGIC III Image Processor to improve focus speed and accuracy, as well as exposure and white balance.

The camera is equipped with a long 6x optical zoom. Canon's own Optical Image Stabilizer Technology keeps images steady and blur-free all through the zoom range--even in low light--by detecting motion and generating a corrective signal. Because it is an optical system, more corrective movement is allowed and there is no degradation of image quality.

Creative Power in Your Control
Full range of shooting and recording modes including JPEG + RAW for the ultimate in creative control.

The PowerShot G9's RAW mode lets you shoot images without JPEG compression. It gives you clearer images and complete creative control in editing. RAW images are transferred directly to the computer where they can then be edited using image adjustment software or a processing application to adjust your images as you please. The camera can also be set to allow the simultaneous recording of both RAW and JPEG images while shooting.

With under a hundred bucks separating the first five models, a consumer might well be in a minor dither about which to get. Currently most Amazon consumers are bucking the adage "newer is better" and going with the SD600 (which the tech people at Cnet support, giving it a rating identical to or higher than the slightly larger and heavier SD700 and recent SD800 and SD900, both with Digic III processors). Perhaps their thinking is like mine: first, its dimensions (width, depth, and height) are smaller and its weight (under 5 oz) lighter than the other six models (the 500's are the largest, and the 630, in fact, is a bit of an oxymoron: a bigger screen to accommodate failing eyes but tighter and tinier controls for those same eyes to locate and navigate); second, the 600 is the only one of the seven that maintains the original Canon Elph aesthetic of perfectly square angles at all corners of the camera (the contoured look that Canon is beginning to introduce is, I confess, a slight offense to my eye). Finally, in the category of set-up time for the first and each subsequent shot, the 600 is comparable in speed with the other models, rated a nano-second behind the 800 but better than the 900. Moreover, the price at this time is right (though don't expect this model to be around much longer). If you can live with a "mere" 6 megapixels and shoot with a sufficiently steady hand to ignore the absence of the 700's image stabilizer feature this may very well be "the one" for you. (Not for an eternity, but in our world of rapidly changing technology even an "extended honeymoon" of several years has to be considered equivalent to a lasting marriage.)

If it needs a further recommendation, my botanist son-in-law, who owns an SD500, is about to order a supply of the smaller and lighter 600's to put in the hands of his students in the field.

Postscript: Contrary to a later reviewer's claim, this camera does not have an "anti-shake" feature like the SD700. I've never had a problem with shaky pictures, but should you observe jittery images, try shooting through the viewfinder for a firmer grip (which is lacking, by the way on the SD630). As for a 6 megapixel lens vs. a higher number, only the sharpest eye would detect any difference in quality of resolution--and even then it would have to be an image blown up to wallpaper size. Finally, the cost of SD memory cards has come down by 50% in just the past several months, so it makes sense to go for the larger (1 GB) card. Also, I would spend the extra fifteen bucks for the faster speed of the Sandisk Ultra II card. (If you like to check the results of a shot the instant after exposure or if you transfer large numbers of shots to your computer at the same time, you'll notice a difference). If you're content with a conventional SD card and want to save a few additional bucks, go with Kingston (as good as Sandisk, in my experience, though I'd stay clear of Lexar, which has given me trouble).

485 of 502 people found the following review helpful: 5.0 out of 5 stars A week in Boston - 400+ photos and not a bad one in the bunch!, May 9, 2006 This review is from: Canon PowerShot SD600 6MP Digital Elph Camera with 3x Optical Zoom (Electronics) This is my third - and possibly final - digital camera. It does everything superbly and in a size I can just throw in my pocket so it's always there. Before the SD600 I had a Canon S100 2.1 mp [a great camera] and a Sony DSC-W1 5.1 mp [a piece of $%#@ - every other image blurry].

With the Sony less than a year old, I couldn't put up with it anymore - it was time to go back to Canon so I wouldn't miss any future shots. I got the SD600 at Best Buy 1 day before leaving on a week-long trip to Boston. My 10-yr old daughter was studying the Revolutionary War in school so I was told to take a lot of photos and "Dad, make sure they aren't blurry like all those others." [She's got the old S100, so she's not worried].

Since I'd already had the old S100, the controls were familiar. Best Buy had a 1GB PNY SD chip on sale for $39, so I had room for over 500 photos, plus I picked up an extra battery.

In the week in Boston I shot day, night, flash, long exposure, high light, low light, drizzle, rain, sun, and even a short video of Morris dancers in Boston Common. Every shot was great - and not one blurry, even when the 'shaking hand' was on. I'm not sue that the image stabilization with the SD700 would be all that necessary.

I found that indoors [my greatest fear since the Sony made you worry about every shot] with reasonably good lighting I was able to turn the flash off and shoot with natural light. I've not yet had the time to play with the various modes - just straight turn it on and shoot [both of which were very quick with minimal delay].

Everyone we were with were greatly impressed by the 600's size, style, and images on the LCD - and surprised to see me turn it on end to show full screen portrait format shots [very cool]. Even friends with the SD450 [my Christmas recommendation] wanted to trade theirs in.

I was able to get over 150 shots - maybe a quarter with flash - without recharging [I just stuck the little spare in the coin pocket in my jeans and didn't worry about it].

The software's great, too. I used the old ZoomBrowser EX with the Sony, so it was nice to see this updated and much more functional. I might not have to use Irfan Skiljan's IrfanView package anymore.

I'm sure that over the summer I'll find all those bells and whistles to be entertaining, but for just taking pictures, I don't think there's anything more I'd ever want. Now if I can just find someone to take the Sony... and I'll throw in my old Omega D2 enlarger for free!

The SD600 is as close to perfect as you can get and all I'll ever need.

38 of 38 people found the following review helpful: 5.0 out of 5 stars Great quality with a lot of versatility, November 27, 2006 This review is from: Canon PowerShot SD600 6MP Digital Elph Camera with 3x Optical Zoom (Electronics) Funny how this camera seems to be tested in Boston. I bought this camera specifically for a trip to Boston. I thought my brother's SD450 was the best digital camera I've ever used, until I got the SD600.

I took TONS of pictures in different lighting and all turned out great. I shot everything from plates of food inches away to soccer games with players clear across the field.

Certain settings worked better than others for different lighting situations. It really just depends on what color tones you prefer. I prefer warmer tones and the camera worked really well. For the basic point-and-shoot shots with the setting on automatic and flash, I thought the colors were very true to life.

The video feature is really great as well. Playback is amazing on the large LCD screen. The newer version of this camera (SD630) has a larger display of 3inches but I actually prefer my 2.5inch screen. THis is because when I tried out the SD630, I'd get finger prints on the screen just trying to manuever the buttons. I don't have this problem w/ the SD600. I am able to avoid touching the screen while changing the settings on my camera.

The best thing about this camera is that it is ready almost instantly after you turn it on. No waiting for an annoying flash to warm up. It also takes a picture right away when you press the button. Hardly a delay compared to other digital cameras.

I don't have much else to add to this review that hasn't been already addressed. This camera with its numerous settings is far better than any old point-and-shoot camera. I think it's a great compromise between a professional camera and a point-and-shoot. It's quite versatile for those who like to play around with settings and effects. For the price, this camera rocks. 3 people have already been convinced into buying this camera after seeing me use it.

This year, with Canon's release of the A570IS, I decided to upgrade, driven by the addition of optical image stabilization (IS). While the IS is impressive, I was surprised by other improvements that Canon has made. Image noise levels are significantly lower and more controlled for higher ISO captures. The Digic III processor seems to make more intelligent decisions about lighting and flash exposure, especially when its face recognition is engaged. Add a dramatically better quality LCD screen, slightly higher 7.1MP resolution, improved case, and support of high capacity SD cards, and I doubt I'll need to upgrade any time soon.

Like the A540, the A570IS is for me a perfect balance of size, speed, and photo quality. The A570IS is the same physical size as the A540. It's small enough to fit in a coat pocket or small belt case yet uses 2 AA batteries.

Like the A540, overall processing speed is very fast unless you're taking flash pictures (and then you should expect about 4-6 seconds between flashes depending on battery level and what flash strength the camera selected). Note that flash time is significantly better with high-capacity rechargeable NiMh batteries than with standard AAs. And, unlike some other cameras I have tried, the speed of the user interface (especially during playback) is very fast.

Picture quality in general is excellent, even in low light situations. Noise at higher ISO is significantly more controlled than the A540, perhaps a benefit of the new 7.1MP CCD and the Digic III image processor. According to the documentation, noise reduction is applied at slow shutter speeds of 1.3 seconds or greater, and this can slightly slow down shot-to-shot time. There is no option to disable or adjust the noise processing, but in my experience the results are very good. When noise reduction is applied, there is a slight loss of detail compared to the A540, but the results are noticeably better on the A570IS with its built-in noise reduction than post-processing noise on pictures taken with the A540.

In my own head-to-head comparisons between the A570IS and A540, the A570IS has better light metering and noticeably sharper detail on indoor shots without a flash (especially when image stabilization is engaged). The A570IS does favor slightly higher ISO in auto modes than the A540, giving generally better results without a flash. However, when taking close-up pictures with a flash, the A570IS doesn't seem to select anything lower then ISO 200, sometimes requiring a manual ISO override in Program mode.

The A570IS offers a new ISO 1600 mode, but I'm not quite sold on it. Without a tripod, under low light conditions, ISO 1600 does offer the opportunity for blur-free photographs not possible with ISO 800. But the level of noise and artifacts from the noise processing don't give a very usable picture.

The A570IS raises the bar with optical image stabilization, which only works when the camera is held horizontally. One of the biggest limitations of consumer digital cameras is the need to hold the camera steady to get a clear shot. At higher zooms and in night shots this problem can be compounded. I've taken a number of shots with and without IS, and it is useful but not a "magic bullet" for poor shots. Small details like far-away signs at night become clear when the IS is engaged. You can set the IS to run continuously during preview, only when the shutter is released (slightly lower battery drain), only on vertical movement (better for objects that are moving horizontally), or disabled (I have yet to find a reason to do so). And, unlike many cameras I've seen, the IS works in video capture mode.

Like the A540, the A570IS offers full manual controls. With the A570IS, Canon adds two more modes (Kids & Pets and Indoor) to the mode selector wheel (instead of having to find them on the Special Scene menu). The A570IS also adds a new Aquarium scene mode, while removing the useless Color Swap and Color Accent modes. Canon has also removed the "My Camera" customization menu (for changing the startup picture and various sounds) which I never used on my A540.

Although I never expected to use it, the movie mode is excellent. It's still not a replacement for a dedicated camcorder. But I have used it on a number of occasions to capture audio and video when a picture just won't do. Standard movie mode is 640x480 (VGA) quality at 30fps, but you can raise the capture to 60 fps at 320x240, or lower it to 15fps at 160x120. The A570 can now capture video up to 1 hour or 4GB whichever comes first. Video files are very large (around 1.9MB/second at 30fps) but they compress extremely well with QuickTime Pro's MPEG4 codec.

With the A570IS, Canon also addressed some of my minor complaints about the A540. Most notably, the LCD screen is much higher quality and higher resolution. The case plastics seem more solid, the small rubber door covering the USB - A/V - power ports pivots open from the side not the top, and the handle area no longer has a chrome insert which had a tendency to fall off. The ring that covers the conversion lens adapter mount has a chrome trim, making the camera more attractive but at least on my A570IS it is more difficult to remove than the A540.

Once again, I looked at the Canon A710IS which offers a 6x optical zoom, but has the same 7.1MP sensor, optical image stabilization and user interface with the older Digic II image processor. In the end, after trying both cameras in the store, I again settled on the A570IS. The A710IS is noticeably larger (about 0.25 inches wider and slightly taller), and the more complicated lens takes longer to startup and to zoom. Both cameras have a limited number of stops in their zoom range, but this is noticeable on the 6x of the A710IS where it is not noticeable in the 4x of the A570IS. For me, the larger size wasn't worth the extra zoom. And the benefits of Digic III are impressive.

In summary, Canon A570IS Pros:
- 7.1 megapixel sensor, 4x optical zoom
- ISO 80 to 1600
- optical image stabilization for higher ISO or zoom, even during video capture
- optical viewfinder for shooting with the LCD off
- full manual controls (shutter priority, appeture priority, full manual)
- preset and custom white balance control
- outstanding photo quality, even in relatively low light (good color balance, very low noise at higher ISOs, almost non-existent chromatic aberation)
- Digic III processor offers face detection, makes more intelligent decisions on exposure, and flash levels
- very good results from built-in noise reduction for slow shutter speeds of 1.3 seconds or greater
- very fast startup and shot-to-shot speed (flash not withstanding)
- excellent and speedy auto-focus even in low light (although the AF assist light can slow this down)
- orientation sensor recognizes if you have rotated the camera to take a shot
- flash adjusts angle based on wide-telephoto zoom
- built-in red eye reduction during playback lets you select an area to remove red eye and save as new or overwrite the existing image
- surprisingly usable movie mode
- outstanding user interface: options are well laid out and easy to locate, very well thought-out record and playback options
- extremely fast user interface and playback performance, even zooming in on photos
- high resolution LCD screen
- well built case, very comfortable grip
- uses SD cards and supports high-capacity SDHC (takes advantage of high-speed SD)
- uses 2 AA batteries (at least 2500 mAh NiMh rechargeable recommended)
- very good battery life (approx 400 shots on 2 rechargeable NiMh AA, with the display on)
- replaceable lithium battery protects settings when changing batteries
- supports optional high-power flash, conversion lenses and underwater case

Cons (to me, all very minor):
- flash recharge time is acceptable but not great (4 - 6 seconds between shots using NiMh batteries)
- preview display blanks while flash recharges
- Auto ISO for indoor flash close-up pictures doesn't seem to select below ISO 200; you can force ISO 100 in Program or manual modes
- ISO 1600 is of questionable real-world use because of noise and artifacts from noise reduction
- noise reduction cannot be adjusted or disabled
- it is possible to insert the SD card upside down and you don't realize until you try to close the cover (would be easy to break the cover if you force this)
- the markings for the battery orientation are difficult to read
- no RAW image support, but you can select from 3 different compression ratios for image quality
- bundled 16MB card is useless - buy a 2GB card

TIPS :
1) make sure you do a low-level format before you use your SD card in this camera, even if you had formatted it for another Canon camera. It makes a significant difference in shot-to-shot speed
2) always use high-capacity (2500 mAh or greater) NiMh rechargeable batteries - the flash recharge time is much improved (though still 4-6 seconds)
3) for indoor flash close-up shots, may need to override ISO to 100 for better quality
4) for outdoor shots in bright sun, setting exposure -2/3 gives better control of bright areas
5) if you use the conversion lens adapter, don't plan on using the built-in flash which is partially obscured by the adapter. I haven't tried it, but would expect the external flash to not have this problem.

I wanted a small compact camera with me when I don't want to lug around my DSLR + lenses and equipment. After a previous good experience with the Canon A720 IS, the new A590 IS seemed like a good choice. Since I'm an advanced photographer, I'll focus on the advanced features of this camera. The auto modes work as well as any other camera in its class, but the extensive manual features is what sets apart the Canon A series. What I like about the camera:

+ Compact, stylish. It's smaller than older A Powershots, and the dark grey color gives it a seriousness compared to the typical bright silver finish.

+ Image stabilization works very well, it allows me to take blur-free photos 2-3 stops below the recommended shutter speed, that means at 35-50mm f2.8 1/10 sec shots are CONSISTENTLY possible indoors without using flash.

+ Good image quality. Expected from Canon, but even better is adjustable contrast, saturation, and sharpness settings, along with the typical JPG compression and resolution sizes.

+ Fast and responsive. I was surprised how responsive this camera is even compared with my DSLR. Shutter lag is very low for a compact digicam, and when I pre-focus with manual focus, it's even faster.

+ Manual modes. Aperture priority and shutter priority are great, the M mode is even better than other A Powershots such as the A720 because now there's a light meter on the right side that adjusts live based on what the camera thinks is the optimal exposure setting. And you can adjust aperture/shutter speed and see how it affects the final exposure. Ideally a live histogram would be even better, but this is very handy.

+ Manual focus. Although the LCD resolution is not good enough, even with the point zoom option, manual focus helps in close-up work and pre-focusing for action or creative photography.

+ Manual flash modes. In addition to automatic flash. The manual flash allows me to adjust the flash power in 3 levels, and prevents a pre-flash. This last part is important for using a remote optical slave flash. I can basically take professional looking studio pictures with this camera with my external flash equipment.

+ Optical viewfinder. I don't use this much yet, but can come in handy in bright sunlight conditions, or when battery conservation is needed.

+ Battery performance seems improved over previous A powershots too. The official specs give it 220 shots on regular alkalines and 500 on rechargeable NiMHs. Good news is they use common AA batteries that you can buy anywhere instead of proprietary models with specific chargers.

Now the negatives. I hope Canon can improve these aspects in their future models.

- Slow flash recycle times. This is to be expected from a camera that takes AA batteries. Would be nice if the LCD didn't blank out after a full flash discharge. Not a big deal since I use an external flash anyway, and the camera's flash is manually set to medium output as trigger (so recharge is faster). I would not want to give up the AA battery convenience for a faster flash recycle time though.

- Higher resolution LCD. The 2.5" 115k resolution LCD is ok for framing and casual browsing, but higher resolution would be nice.

-Live histogram while shooting. This feature is available when reviewing a photo, but not live. Other manufacturers have implemented this, and Canon should also, especially since the unofficial CHDK software mod allows such a feature.

- Larger aperture would be nice. Such as f/2.0 (instead of f/2.6) at the wide end, and f/4.0 (instead of f/5.5) at the telephoto end. That way a lower (& less noisy) ISO can be used in dim conditions or when fast shutter speeds are needed to freeze action. All the electronics in the world can't replace a good large lens. Also allows more creative depth of field control.

- A wider wideangle would be nice, 28mm instead of 35mm (35mm equiv). I'd rather see a wider wideangle than a longer zoom.

- Video feature is not ideal. Optical zoom is not available during recording of video. And the more efficient MPEG4 compression is not used, so video files tend to be large. Also noticed at 640x480 resolution, the highest fps is now 20 instead of 30 from other A models. A definite step backwards.

- Noise at higher ISOs. This is due to the smaller sensor on compact cameras. But 8 MP is probably the most pixels that can be crammed into a small 1/2.5" sensor. I'd rather have a cleaner picture at 6-7 MP than a noisy 8 MP picture. And if in-camera noise reduction is used, I'd like to see an adjustable setting for how much is being applied.

- And if I were to be really critical: There's no indicator of what optical zoom level I'm at. Slight image noise is noticeable even at ISO 80 when I zoom in really close on a monitor view. When at the widest angle & aperture, there's slight barrel distortion and blurriness on the corners. Not many compact cameras can do better in terms of image quality, but I'm pointing them out here because even though this camera beats most of the competition, it still has room for improvement.

So overall it's a great camera for the price. Offering great image quality with the auto settings for the casual user, but also a powerful set of features for the more advanced photographer.

The results are pretty good. (How do I know? Because I've actually gotten to use all of these cameras. I earn my living at Walt Disney World writing a travel guide, and nearly every day guests ask me to take photos of them with their own cameras, which most often are Canon PowerShots.)

Here's my opinion of the top-selling "A" series cameras:

A580. This 2008 model is an A590IS (see below) without image stabilization and with semi-automatic instead of manual controls. I'd spend the extra bucks for the A590IS, because those two features can make quite a difference.

A650 IS. You can do a lot with this sweet little camera, though it may be more than you need. It has a flip-out LCD panel and the option of manual controls. The shots I've seen from this model look great. Keep your ISO under 800 and you won't get any noise.

A720 IS. This fully-loaded 2007 model has all the toys, including a 6x zoom (35mm film equivalent of 35-210mm), image stabilization, adjustable flash power and optional second-curtain flash. This last feature means you can make the flash fire at the end of a long exposure, instead of the beginning, so moving subjects streak into focus instead of out.

A470. This 2008 camera is great for kids or anyone just looking for a good basic camera. It includes Canon's face detection technology and has a zoom lens, 14 shooting modes and the ability to set exposure compensation, ISO and white balance manually. Plus it looks great, and is a good bargain.

Finally, the A590IS (the camera on this page) is a 2008 upgrade to an older model, the A570IS. The face detection system works a little better than the one on its predecessor, and the new model is slightly rounder and easier to grip. I personally like that it has automatic and manual controls, though I haven't seen anyone using the manual set yet. Overall this camera is a fine performer, a great bargain and I think the best buy of the bunch. I bought one for myself.

The A590IS is the best point and shoot under $200 today (closer to $155 most places). I own an SD600 and my wife, friend, and father (all different people mind you!) own A570IS's. The A590IS is the new version of the A570IS, 2007's best selling camera. Generally, see the rave reviews of the A570IS if you want to know the major pros and cons (in summary: Image Stabilization is amazing, noise is limited, features of all there including manual controls [though no auto-bracketing which no other cameras at this price point have regardless], final picture quality is superior to all other brands at this price point and type, [i.e., point-and-shoot], good size). Rather, here I'll address the main improvements over the A570IS (which is about $30 cheaper):

(1) The A590IS has 8mp vs. 7mp on the A570IS (negligible difference)

(2) The A590IS is slightly faster between non-flash shots BUT slightly SLOWER before the first shot can be taken and slower between shots where flash is used (less than .5 second difference according to CNet)

(3) It's charcoal/gray - minor change from silver, but I like it a lot.

(4) It's "rounder" on the edges but no less stable in your hand, neither camera is too slippery like other overly polished cameras (also, no finger smudges as a result).

(5) There is sometimes increased noise with higher MP cameras, this is NOT the case here - noise levels are similar.

(6) there are some minor additional shooting modes and improvements to other shooting

Cons:
The only change that is not an improvement is the lowering of the frames per second in the video mode.
A570IS: 640x480 = 30fps --- 320x240 = 60fps
A590IS: 640x480 = 20fps --- 320x240 = 30fps

Frankly, this is a bummer and cannon should correct it with firmware ASAP; however, the lower FPS is still quiet good, but this was a pointless change that is not appreciated -- the reality is that most people don't use video often and those who do will see a minimal difference ... if you're paying that much attention to the video you may be more interested in a different camera or a video camera.

Conclusion:
This will be the best selling camera of 2008 and it's a VERY safe purchase you won't regret (unless it gives you such a new found love for photography that suddenly you wish you had a Canon S5 or G7 ... which are more than twice as expensive!).
