Regardless if it's .2MP more, the quality is still extremely poor. "Don’t be fooled by the promise of 10.2 megapixels. The images look more like they were taken with a 3.0 megapixel camera. " - from
http://www.product-reviews.net/review/20081124/samsung-bl103/ (always read some reviews before you buy a camera).
The samsung has digital image stabilization; anyone that knows a few things about cameras knows that this type of IS isn't very good. While it's better than nothing, OIS (optical image stabilization) is much better.
Also, I never said the samsung didn't have face detection. FD is usually a gimmick anyway. My TZ5 has it and I never use it, using any other focus mode works just as well.
I do agree that for more "average" consumers, the samsung is a better deal. In the long run I'd prefer and recommend a camera that will last a while though. One of my friends bought a samsung (S860), that has digital image stabilization but pretty much every picture without the flash comes out blurry (with my TZ5 I can take pictures without flash fine, since it has OIS). She's also having issues with the lens motor (won't retract the lens anymore, and has to push it back in), and I know she takes care of her camera, and it's almost ALWAYS in a case.
Having a better lens in a smaller camera is noticable. Read up on it, I've read plenty.
The post above me explains a lot too. I agree with it all
And simply put, if the samsung was a better deal, higher quality camera companies like canon would be out of business.
The SD790 is on spoofee's more recent deals, if you want a larger screen for the same price I'd go with that since this deal is dead now.
