I don't know of any camera with 8X optical zoom, but how about 10X optical zoom and small.
Nikon has the S10 which is a replacement for the older S4.
Here is the press release on the S10:
The very last line in the specifications list shows the camera size in millimeters and inches.
Hi! I'm so thrilled to have found this site. I'm wondering if anyone can offer any advice. I'm looking for a camera with 5+ MP and at least 8 optical zoom. I'd like it to be as small as possible, which I know is hard to find! If anyone knows of a camera like this please let me know. We are about to have a baby and I want a nice digital camera, good zoom and compact. Thanks so much!
