    a fisheye is a lense, basically a wide angle,

    That's the amount of zoom. 1x is the human eye I believe. The smaller the x the more extreme the fisheye.

    It's usually easier to go by millimeters. If you shoot digital you'll want as low of number as possible, something like 8-12mm. If you shoot film you can get away with a little more zoom, 16mm or lower should do just fine.

    I think 8mm gives you the full 360 degrees. But it also makes it into a more circular image as if the corners were vignetting.

    Does Canon make any fisheye conversion lenses for their powershot A-series digital cameras?

    I think you mean 180 degrees.

    i use a 15mm sigma fish eye on my nikon at the mo and its great. it's great for close up sports photography. it gives a 180 degree view. i've seen a number of 360 fish eye shots before usually of skyscrapers and architecture.
