Digital Home Thoughts: Comparison Review: Casio EX-S770 vs. Casio EX-Z75

What About Performance and Image Quality?
In use they are functionally identical. During my hands-on tests, I found the startup times to be the same, the shot to shot time to be about the same, and battery life was nearly identical. Given the fact that they appear to have the same image sensor and nearly the same optics, this should come as no surprise.

The various “best shot” modes were easy to access, although I found myself wishing for a “blog” mode which would automatically create copies of the pictures in smaller sizes for use online. In actual use, I tended to rely on the auto mode for white balance and flash, which worked fine in better than 9 out of 10 situations.

I shot a series of identical subjects to see if I could find any difference between the images the two cameras produce, and there really wasn't any. Here are various sample shots from both cameras for comparison (the Z75 images are smaller due to fact that I used the "normal" quality level):
