Question: S2 or S3 Is this camera Canon Powershot S2 still a good camera tho they came out with the Powershot S3?  What does S3 have that S2 doesn't?
Document: I have been eyeing this camera for over a year, since Chris Pirillo recommended it. I have owned several Canon Cameras, including the A510 and A520. Well, when the S3 came out and the price dropped on the A2, I made the leap and bought it. It is great, great pictures, great recycle time, GREAT ZOOM! And small enough to  still be able to sneak into places.I do not need the higher res of the S3, so the S2 is the camera to get
The Powershot S2 IS is an excellent value, now that the price is below $350. The 12x, optically stabalized zoom lens and 5 megapixel sensor delivers crisp images, even in lighting less than ideal. It's modes are easy to navigate, and is truly a best in class (tied with the S3) for videos. Video quality is very good, particularly the stereo sound. Afraid you'll miss a good shot because your shooting video? No problem! You can take high-rez still shots while recording video!
Let's start with some bias, I have owned Canon cameras since the early '80's. Having said that, I still think I got a great deal and more camera than I expected. This is not a top of the line Rebel, but it is a *serious* upgrade for those with entry level point-and-shoot cameras who want more camera for not much more money.I bought the Powershot S2 as a "last year's model" and saved about half the retail price after the S3 was released.
This camera is top notch. As far as high zoom goes, the Powershot Sline has been stellar. I have the S2, my roommate has the S3 and the S5 just came out and is looking mighty fine.If youre looking at this camera because you want a high zoom high feature camera for the price of a 8 mp point and shoot, then you're looking in the right place. The S2is will never grow old.
The only solution is to take the memory card back and get another brand. I got this card, it gave me the above errors. I got a different 1GB model (a 150X speed one) and it worked on the Canon Powershot S2 IS, no problem). Although 6M is cutting edge for low-end cameras, you will pay a 1/3 more for the S3. This is a fantastic 5M model for the price. The lens is outrageously good (maybe even SLR pro quality).
I bought this camera because I wanted to change my Canon A40 for a higher model. I love to take pictures of my travels and I found that the S2-IS is a good camera for who wants to take good pictures but is still learning and acquiring the skills required for professional photos. I was thinking to buy the S3 but I think that the relation benefits/cost of the S2 is so good for this price.
By no means am I a professional photographer, but I adore the art of photography. I previously owned a Canon PowerShot S30 that I have been using that camera since 2003. I am happy to say that through all my clumsiness that camera is still as good today as it was the day I bought it. However, it didn't have the features I desired in a digital camera...So I did some research, and ended up with the Canon S2 IS.
Are accessories like the lens converters, the wide angle and long angle lenses, and the filters that I purchased for the Canon Powershot S1 IS compatible with the Canon Powershot S2 IS or the Canon Powershot S3 IS? I am looking to updgrade, and I want to know what costs I will have other than the camera itself and the memory (since the S1 IS used Compact Flash memory). Thanks!
I bought the Canon PowerShot S2 IS about a year ago, and have taken about 2,500 photos and about 15 video clips with it. Overall, I am very happy with it, and if I were buying a new camera today, I probably would get the S2 or S3.Things I like about the S2:* Extended zoom (12x). I use it often. * Image stabilization. Particularly helpful when using a high zoom factor, or when shooting in low light with a low ISO setting.
I definitely recommend Canon Powershot S2 IS or S3 IS.
Answer: According to latest Consumer Report the S2 offers better print quality over the S3. No real difference between the two other than price.
