I had an A75, but the CCD eventually went bad. I had to bang it around
repeatedly in order to get it to "stabilize" the image, and then I could
take a few pictures. I loved that camera, though.
I replaced it with a newer model (A570) which has more mega-pixels, etc, but
I don't think it takes pictures as well as my old A75. One feature notably
lacking is the manual shutter speed control. On my A75, I could set it all
the way up to 30 seconds, which made for some fun night-time photos. The
new camera has only automatic settings. But more than that, the pictures
just look washed-out. It's like it's trying too hard to eliminate shadows,
and the end-result ends up looking very flat and grainy.
Maybe I'll try this out, though.
