Canon PowerShot G3 Digital Camera (Canon-8120A001)

| Overall rating | 84 |
| Image quality: To gauge picture quality, we take a series of shots, with and without flash, at 640 by 480 resolution and at the camera's highest resolution. We photograph a complex still life and a mannequin to see how well each camera captures details and subtle colorings such as skin tones. A panel of judges reviews the on-screen and printed photos and assigns image-quality scores; we then average those scores. | Very good |

Canon PowerShot G3
PowerShot G3 Digital Camera (Canon-8120A001) Review, by Alan Stafford January 27, 2003

WHAT'S HOT: Having greatly admired its predecessor, the PowerShot G2, we had great expectations for the 4-megapixel PowerShot G3--and in most respects it didn't disappoint us. It takes great shots in nearly all settings, though the 5-megapixel Olympus C-5050 Zoom handily outperformed it on our most resolution-dependent test, a cropped and magnified image. Canon says that the G3's new 12-bit analog-to-digital converter (an improvement on the PowerShot G2's 10-bit converter) captures four times as much color information as the G2; and we saw superb color accuracy in our test photographs. The G3 retains the G2's bright, clear LCD display, which unfolds from the body for overhead shots or self-portraits. The camera takes great macro shots; pressing a dedicated manual-focus button on the body magnifies the middle of the image on the LCD screen to aid in focusing. Similarly, if you zoom in during playback, the G3 displays a small map that indicates your position in the image--one of the camera's many small but thoughtful touches.
The camera has a slew of advanced photographic features, including nine white-balance modes, nine flash modes (including a manual flash adjustment), and focus bracketing (in which, after a somewhat complicated setup process, the camera takes three shots of varying focus values).
In our battery tests, the PowerShot G3 held out for 447 shots, or about 2.5 hours of life--roughly 40 percent better the average for competing cameras. If you want a backup rechargeable battery, you can get one for about $60. Canon provides great documentation for the camera, including a helpful quick-start guide, a manual for the bundled software, and a comprehensive manual for the camera itself.
WHAT'S NOT: A few of the G3's features seem unduly perplexing. For example, several LEDs on the back of the camera blink in code to provide status information, such as whether the focus is locked. (Several Canons have these lights; see our review of the PowerShot S40 for a summary of what they mean.) We preferred the on-screen signals: To indicate whether the focus is locked, for example, a box in the center of the LCD will glow green for yes or orange for no. Another source of confusion: For some frequently used settings, you press a Function button to bring up short menus, but for others you have to press a separate Menu button. The Set button which confirms choice for both types of menus, is paired with the Menu button, but the Function button sits with another set of controls that have little relation to it.
The new 4X zoom is longer than the G2's 3X zoom, but at its widest setting it partly blocks the flash, casting a noticeable shadow in the lower right corner of the image. Zooming in just a bit will help you avoid the shadow--but that nullifies some of the benefit of the longer zoom range. The lens is quiet and accurate, but it's slower than those on some other cameras. Canon says the G3 takes shots more quickly than the G2, but other cameras in this price range are even faster.
You can capture movies of up to 3 minutes (compared to 30 seconds on the G2). But like the Canon PowerShot S230 Digital Elph, the G3 does not adjust its aperture in movie mode, which can be especially problematic indoors. Every other camera we've tested recently adjusts its aperture values during movie capture.
WHAT ELSE: Canon includes an ancient image editor, Adobe Photoshop 5 Limited Edition--the precursor to Photoshop Elements, which is now at version 2. It also bundles a remote control, which you can use during playback (with the camera connected to a TV, for example) or during shooting (say, from a tripod). The G3 accepts a telephoto attachment (about $140) and a wide-angle adapter (about $160). We tried the latter, which worked very well, aside from producing some predictable barrel distortion.
The G3's photo-stitching mode (found on several Canon models) helps you line up several vertical or horizontal shots so you can later combine them, using included software, into one very tall or very wide image.
UPSHOT: The PowerShot G3 rates as a minor update of the very good G2, but other cameras have seen more significant improvements. We like the G3's picture quality and sophisticated features, but it still has room to get better.

Strengths: None
Weaknesses: Plenty
Overall: All the critiques on the downside of this camera are right on target: Bulky; viewfinder obscrued by barrel of camera; blurry pictures; discolored; etc., etc.. And the list goes on. I don't understand how this camera could even be rated anything except UNACCEPTABLE. And, I certainly cannot fathom some of the other posts here complimenting this camera and giving it anything other than a two-star rating.I received this as a gift from my wife. I have a two-megapixel camera, which I've owned, now, for three years. When I compare the same-scene photo shots, taken one right after the other, from both cameras, there is no comparison: my old camera wins hands-down. The photos of my oldie are clear and crisp; those from G-3 are enough of a blur that one notices it immediately. And, in printed form on photo paper, the differences are more than obvious. This G3 is a camera one just cannot trust to take that one precious moment in time and capture it. Period. So, do yourself a favor: forget purchasing this hardware. Or, you'll end up in our shoes: $500 poorer; told by tech support it's YOUR FAULT that they're blurry, you shake; (my wife and my whole family have the "shakes" too, I guess) and, there's nothing wrong with the camera, so don't bother to send it back in for repair. (Ya gotta love it!!!!)Anyway, please spare yourself the pain. You'll be delighted you heeded my warning.Ernie

Strengths: superb battery life. excellent picture quality. outstanding features
Weaknesses: it is a little bulky
Overall: I was really leery about switching from a 35mm to a digital camera and after much research I decided on the G3 and have not regretted it yet. I have taken thousands of pictures after purchasing a 512 mb card. I blow up many pictures to 8x10 and they come out flawlessly. I would strongly recommend this product to anyone.

Strengths: Excellent quality hardware, fit and finish. Versatile functions. Swivel LCD viewer is a fantastic asset. Photo speed is good (use CF Ultra II). Battery life is very good.
Weaknesses: Auto-focus takes some getting used to. Lens partially obscures optical view finder. Battery life indicator not evenly progressive.
Overall: The Canon G3 is an excellent mid-size digital camera for the price. I have owned one for 7 months as of this writing and have had very satisfying results. I highly recommend it for any photographer that wants an ample range of features, while keeping the base cost to less than $500. It is nicely weighted, feels solid, and is small enough for easy traveling (compared to an SLR). It has versatile functions for a variety of photographic situations, including aperture priority, shutter priority, and full manual. Great night photography results are finally in reach without having to have a lot of skill! The 4-megapixel capacity is very adequate and photos are professional at maximum resolution with minimal compression. dpreview.com recommends the G3 over the G5 (see their site for details). The swivel LCD viewer is a fantastic asset, allowing highly creative photography (you can put the camera where your head won't fit!)--I use it extensively and can't imagine having a digital camera without it. I wish they made them on Digital SLRs! The greatest weakness of the camera is the auto-focus mechanism, in that it doesn't always focus on what you're looking at. And with the very small LCD viewer, you may have a blurry photo that looks in focus because of the viewer size (it scales down the actual photo size, of course). I've had a number of photos turn out a bit blurry, because the G3 locked onto a wall rather than the people in front of it. This isn't a "don't buy the camera" problem--you just have to get used to how the camera functions. Next to that, I agree with the other reviews, that another notable weakness is the optical view finder. It is partially obscured by the lens and even more so with the lens adapter attached (for using 58mm filters). But I only use it when battery power is getting low (the LCD is the biggest drain on the battery, but it is easy to use it sparingly by either turning it off with a menu option or closing it to the body). One minor complaint I have is that the battery life indicator is not evenly progressive. When the first power bar disappears, you must use power cautiously (rather than 50% power left, it is more like 20%). But again, battery life is very good. The only odd quirk I've run into was in 2 different photo situations: When photographing a neon sign that was a purple/blue shade, it did not capture properly--no sign of purple, just blue. Weird. But then, I've heard of other cameras distorting many more commonly encountered colors. It's too bad the G5 didn't stand up to the precedent set by the G3 (kind of like the styling of the new BMW 530i, vs. the previous 2003-1997 models)! The G3 is hard to come by new... but if you find one in nice shape used, I'd get it. It really is a "prosumer" model, delivering professional quality for the photo enthusiast consumer.

Strengths: Great all around Pro-sumer camera. Great color, a full line of features, very expandable.
Weaknesses: Viewfinder Problem (as noted previously), Hard to focus in Low Light situations, some features are not enabled with add on flash.
Overall: I have been very pleased with the purchase of this camera. As far as I'm concerned you can't go wrong. It is a great beginner camera as you can get as technical as you like while still having a very accurate "Auto" feature which will produce a great picture 99% of the time. You can easily add on lenses and filters. With the addition of the exteranl flash it truly is a great all around camera.

Strengths: Optics, Controls and features access, Color accuracy, Superb White balance, Battery life, Articulated LCD, Completeness of package, ie: remote and power adapter
Weaknesses: Infrequent auto focus misses (1 out of 50 or so)
Overall: Like the others before me, I researched this purchase to death. There were very few available cameras with the necessities I desired. Other models considered included the Pentax Optio 550 the Olympus 750. The G3 easily delivered the most complete package out of all contenders and to my mind remains in the top tier of digi-cams anywhere regardless of price. The thoroughness of the Canon approach combined with the high quality of product delivered is very satisfying to me as a consumer. The combination of the thoughtful remote and the video out makes for an easy presentation on any modern TV set. Unlike many cameras with no video out capability, some of them quite popular, screening and evaluating photos is quite easy and requires no computer. This is essential for travel/vacation photos. Along with the supplied 32MB, I have (2) 256MB cards and will have even more when traveling to the Hudson Valley this fall. Large capacity storage is an absolute necessity for these situations (unless one is also taking a laptop along for downloading...I currently do not but am thinking about it!!!) Image quality is superb and the color accuracy (Canon greyscale) is difficult to outperform. I know...I have tried...and failed. Were it not for the increased CA with the G5 I probably would have gone that route. But the trade-off in lens speed required to correct the problem made the G3 a true no-brainer. Color me happy.
