hey /p/ I'm thinking about purchasing a zenitar 2.8 16mm fisheye lens for my sony a100.

Does anyone have any experience with this lens/using it on a sony alpha?

I've wanted to experiment with fisheye for a while and this is the most affordable entrance I can find other than using one of those fisheye extension things you can just attatch to the lens. Are they any good or am I better going for the lens?
