This is one of the better posts I've seen here awhile. Very intelligent and insightful.
I just purchased a Sony W70 a few days ago. It was on sale at Circuit City for 189 bucks. Now thinking of returning it (still unopened) and getting this S3. What do you think? This S3 looks like a quasi-DSLR, but you think it's worth it to give up my Sony for this?
Thanks.
It's going to really depend on what your intent is. If you're going to be using it as just a "casual" digital camera, you'll probably be fine with that one, for considerably less money than the S3.
However, there are some pretty limiting factors in the Sony - only 2 second max exposure vs. 15 seconds on the A710 (and presumably at least that on the S3). This is useful for night time shots, for example, of cityscapes, or pretty much anything that's lit at night.
The Sony does have some respectable options to customize exposure, aperature, etc. The Sony is more of a simple point and shoot camera. And for that purpose, it should be more than sufficient.
If you're looking to step up to more flexibility, the S3 would be a good choice. The reason I chose the A710 is that it's sort of a best of both worlds situation. It has the nice 6x optical zoom (your Sony has 3x) along with all the advanced customization features, but at the same time is fairly compact, only uses 2 batteries, and has a nice "fully automatic" point and shoot mode. The S3 has a much larger 12x zoom. In addition the two Canon cameras have image stabilization, which helps you to take much clearer pictures in lower lighting conditions or at higher zoom levels. Without the IS feature, lower light shots or zoom shots are likely to come out blurry without a tripod.
One thing that I would hold against the Sony (and this is just a matter of personal preference), is that the Sony uses a custom Lithium battery. You
must use this battery, you can't use AAs or rechargeable AAs. This can be a problem, especially if you only buy one battery, as if the battery runs out, you're completely stuck until you can get home and charge it back up. If you want to buy an addition Lithium battery, they're much more expensive than NiMH AA rechargeables. That's what I like about the Canon, you can charge up a bunch of AAs, and not have to worry about your batteries running out, just pop in some more charged ones. And, if you're in a pinch, you can always pick up a pack of alkaline AAs and use them. The S3 uses 4 AAs, the A710 uses 2.
One more benefit of Canon over Sony is that the Canon cameras use secure digital memory cards which are much cheaper than the Memory Stick memory cards that Sony uses.
I guess in the end you'll have to decide if it's worth the extra $100 or so for the convenience of being able to use AAs, the increased custom options, and a much larger optical zoom (digital zoom is a virtually worthless feature - if you'd like to know why I can explain, just let me know). If you plan on taking a lot of pictures, printing out 8x10s, and really getting into photography, the S3 would be a better starter choice than the Sony. If you're content with a more casual and portable digital camera, the Sony should definitely satisfy you and save you some money.
The A710 at Amazon for $255 shipped was really a no brainer for me as it basically has the convenience of the compact size, AA batteries, and also has a quality 6x zoom, image stabilization, and some higher end exposure and aperature controls.
