There's something about the photos the SD700 takes that I don't like. I find hard to quantify what makes them not as good as the ones taken by the SD600, but they seem almost over-processed, a little less crisp, a little less sharp, kind of like images smoothed out in Photoshop. Since the Digic engine is the same as the SD600, I can only theorize I'm seeing the results of the image stabilization and/or the new lens. I didn't like the effect and switched back to the SD600. The SD700 does take slightly better indoor photos that are cleared and less prone to shake, but the difference isn't that great vs the SD600. The SD700 also has a new CCD (the device that actually captures the image) which may be the culprit.
