Summary: Awesome pro-sumer camera
Review: When shopping for digital cameras I looked at the Nikon CP5700, Olympus C5050, Nikon CP5000, and the Canon G3. Yes, all cameras except G3 were 5mp but I was looking for a lot more than just Megapixel power. Not only was I was shopping for a camera that would suit MY casual and artistic photographic needs, I had to keep in mind that my fiance wanted to use this camera as well. Her main focus was having a camera that is easy to understand and use. The Nikon's are great cameras. + They have great optics (CP5700 has great optical zoom)and features, not to mention take great pictures. - The drawbacks were that they were not user friendly for the casual photographer, the LCD screen is a little too small, CP5000 does not take photos in RAW format. Olympus C5050 is a very solid camera with a metal body. + Takes sharp 5mp photo's, has great features and relatively easy to use. - I didn't care much for the tilting LCD screen, it seemed very limited and not very usefull. Photos had some artifacts and noise. My fiance just didn't like the way it felt in her hands. We also looked at the Fuji FPs602. Nice Camera but doesn't take as sharp as pictures I thought they would, and again... fiance didn't like the feel. The Canon G3... 4mp, 4X optical zoom, takes absolutely beautiful photos with detail that challenges all of the above 5mp cameras, easy to understand and use (has a great swivel LCD screen), a LOT of features and add-on options, comes with great software (not to be overlooked), and last but by far not least, received my fiance's stamp of approval (two thumbs up!) A LOT of research went into digital camera's before I made this purchase, and hands down, the G3 had everything I needed plus more. The other cameras were great and I'm sure many people will beg to differ from my observations, but to each his/her own. I have no buyers remorse with this baby, and I never will. Always remember, cameras don't take great pictures, people do!

Summary: Upgraded from G2 and not looking back!
Review: The Powershot G3 is a great camera. Why? Because it can help a so-so photographer take spectacular photos! 4 Megapixels is plenty for all but pros, and you will not be disappointed with the results of this camera. It's slightly lighter than the G2 and packed with even more features. Make sure you get a big CompactFlash card (it comes with a 32MB) -- the 512MB cards are pretty [inexpensive] here on Amazon.com and can hold about 500 photos at a time!

Summary: The Catch!
Review: The catch with the Canon G3 camera, (and perhaps all of digital cameras) is that its unresponsiveness will cause you to miss precious shots. Prior to the purchase, none of my digital camera friends mentioned the delay between pressing the shutter button and the camera taking the picture. No one told me, but I wanted to tell you. This is not the same thing as a film camera. And while it is cool and fun and has no film processing costs... they haven't got all the bugs worked out just yet. Most of the time, my G3 is a well-behaved camera. But once in a while, I run up against it's major flaw: It sometimes takes the picture at some indefinite period of time AFTER you press the shutter button. I am not talking milliseconds. Picture this: Your child is going to do a cannonball off the diving board, so you compose the shot and wait for your moment. When it arrives, you press the shutter release. Splash! The moment passes, and THEN your new G3 camera takes the shot. Perhaps there is a way around this delay. Some feature I could turn on or off, or some attachment I could get... Yes, I push the button down halfway first to avoid the autofocus delay. Yes, I have red-eye off, and yes, I've tried adding a flash. But after trying many adjustments, the camera remains unresponsive when compared to any film-based camera. I own another Canon - an EOS (35mm film) camera. It focuses in a snap. Dim or bright, it would never take a picture AFTER the birthday candles had blown out, AFTER the Tae Kwon Do kick broke the board... Canon's G3 does it consistently. It feels slow to focus, and unbearably slow to shoot. I challenge anyone (who is not in direct sun at the beach at noon) to say it is fast and responsive. And so I must ask, what are cameras for? What task do they perform? Cameras capture moments. They stop time. Because once the moment is gone, it is not coming back. The dive, the kick, the blow-out-the-candles moments are, to me, the reason for cameras. A 35mm film camera captures the moments you want, while these digital cameras (my friends now inform me) all seem to capture the moment immediately following the one you asked to capture. Not all the time, but often enough to be a real problem. Like I said, when the moment is gone, it is GONE. So buy the G3. Buy it for fun, for lack of processing, because you want to use iPhoto, or whatever. But do not assume, as I did, that the G3 has the same ability as [your current film camera] to stop the moment YOU choose. From a dime store disposable to a top of the line EOS, all film cameras share this ability to capture the moment you tell them to. Unfortunately, this digital moment-capturing device called the G3 sometimes captures the moment AFTER the one you wanted.

Summary: 100 % Happy!
Review: This is my first digital camera and I couldn't be happier. I have but plan on selling my Rebel Ti and all of the equipment with it. I love the quality of the pictures. They look fantastic. I can take better pictures with this then my Rebel Ti with a good lens. It's just easier for me since I can make on the fly adjustments.

Summary: The Best 4MP out there
Review: The Canon G3 is perhaps the best 4MP camera out there. I've tried the Sony S85 with the Carl Zeiss lens, but the pictures were too digital. With Canon, you get pictures that appear to be photos, not still camcorder shots. I love the EOS based controls and easy menus. I don't need to go into exhustive review of this camera. Many before me have done that already. I agree with the positive reviews. But there are two things I don't like about the camera that were not mentioned in any previous reviews. 1) The included lens cap is very loose on the camera. Though the instruction booklet says that the camera should display "lens" when the cap and the camera are both on, the camera lens extends out and simply takes the lens cap off by itself. I'm concerned that with the easily removed lens cap, I may damage the lens. Very cheaply made. 2) The body construction - buttons, casing, etc, are too prastic. The G2 was better in this respect. It had a heavier and more sturdy casing. Despite these grieps, I still recommend the camera.

Summary: Cool [Toy].
Review: Yep. This is my first Digital Camera, and what a 'toy' it is!!! I am a software engineer and am very keen into technical details of everything i buy, I spend around 3 months before buying the digital camera; and i must say, G3 worth every single cent i spent on it.
Just a little overview, PowerShot G3 is the flagship of Canon's PowerShot series and its an SLR-like camera, its 4 megapixel and (alsmost) full manual control gives the pictures a touch of brilliance. Whether you are a novice or an expert, its ease of use and functionality goes together. + you can have different kind of lens if you want + flashes, etc. As its 4MP, you might need bigger storage to store high quality images and recording movies (you can record 3 minutes of video). I am using Kingston 512MB CF which works great and is very fast. A good choice could be CF type II, Microdrives that can store around 1 GB of images.
Some things that i didn't like (but hey.. nothing is perfect).
* Main dial is not backlit.
* Lens visible in optical viewfinder. (well thats only for old-school die-hard optical viewfinder fans) use LCD instead which is brilliant and you can twist around too. Overall I'm happy with my toy. :)

Summary: Love it more and more!
Review: I used a Canon Powershot S20 for about 2.5 years and LOVED it! There were a few flaws that I learned to deal with and took thousands of pictures around the world, losing a few that I really regretted. I finally decided to upgrade, and started my research. Canon was an obvious choice, but I did not want to limit my decision, so started researching all brands that would take my Microdrives. I researched, held, tested, and observed 3 different brands. Needless to say, the Canon won, hands down. This camera performs like I can not believe! I bought it for my trip to Beunos Aires, and also used it at the Iguazu Falls, and could not have asked for more perfect performance!!! It was too new to have learned much about the advanced features, so I generally used the Auto mode. This camera is worth every penny, and I highly recommend it! Another point of note: the battery life is incredible!! I did not have a backup battery, and had no need for one. I did have ability to charge it every night, so don't know how long it would have actually gone before dying. This camera will stay with me for YEARS!! 5 Month Update:
I am still loving my camera! Took it to Croatia (very humid), Cannon Beach (very humid), with NO problems! I was worried from a couple of reviews I had read, but experienced no problems. The pictures I have taken are INCREDIBLE, with exceptional detail. I still have NO regrets. Many manual settings that I still need to figure out (or maybe not). I LOVE MY CAMERA!!!!!!!

Summary: The last digital camera I'll buy.
Review: I've been looking to buy a digital camera for a long time and v=finally decided that now was the time. After a lot of research, I decided on the G3. Am I ever glad that I decided on this camera! I've only had it a week, but so far, everything about this camera is making me happy. Forget the fact that it'll probably take me a year to figure out ALL the features this camera has to offer. I've been able to change modes on this thing without even looking at the manual. Very intuitive menus are a big plus on this camera. I charged it up the day I got it, took a bunch of pictures and I don't think the battery indicator has budged from fully charged. The standard battery include with the G3 is a camcorder battery that will allow me to take pictures all day without worrying about charging. I was worried about this after seeing a friend change batteries on his Olympus after about 20-30 pictures. The optical zoom is awesome, and the viewfinder reflects the settings of the zoom. One little minor flaw with this camera is that the lens is visible in the viewfinder, but does not detract from the image at all. As I said, this is the last digital camera I'll buy, and if you are in the market one, my advice is to buy the best thing you can afford and keep it forever. These things may get a lot better in the future, but from what I've seen in the last few years, the technology for digital cameras isn't advancing at the pace of PC's, phones and hard drives. The best 4 Megapixel/4X optical zoom camera available and fairly easy to use. Highly recommended. For more info on digital cameras, go to dpreviews.com

Summary: boxy? no -- GORGEOUS!
Review: You can read the other reviews for specs and performance opinions. I was perfectly happy with my G2, so why did I trade up to the G3? Because this camera is beautiful. The G2 was slightly curvy with a champagne finish -- very homely. The G3 looks like a work of art! Its silver magnesium finish is stunning, and the sharp lines and excellent grip are better than any other camera I've seen. The little digital Elphs were the best-designed, most-elegant cameras until the G3 came along and squashed them.

Summary: Very good choice in it's price range
Review: This is my first digital camera. IÕm very pleased with it so far. I wanted something that is able to take high quality photos but not be so bulky that IÕd wind up leaving it at home all the time. This seemed like a really good compromise. I compared it to the Olympus C5050z, the Sony DCS-F717 and the Nikon 5700. Based on the cameras features and about dozen online reviews, this one seemed like the best all round deal. ItÕs not perfect though. Here are the shortcomings IÕve noticed so far: It would have been a much easier choice if this were 5mp camera. You can see the lens barrel in the view-finder. (I knew this before hand, and itÕs not THAT bad) There is no TIFF format. That would be a nice compromise between JPEG and RAW. To save a picture as RAW, you have to have the display on, this seems like a waste of battery power. It seems to me that after the focus and metering are complete thereÕs quite a lag before the ÒshutterÓ trips. (Again this is my first digital camera and maybe thatÕs just how they all are.) For those of you using a Mac in OS X+ there is no Twain utility to download your pics directly into Photoshop. ItÕs very simple to import via iPhoto 2 and then move them to Photoshop. I havenÕt spent much time with the included software, so I donÕt know what to say about it other than it seems ok. IÕm quite happy with the camera. It comes with a clearly written manual and the learning curve isnÕt too too steep. Yes, I recommend it over the competition.
