I tried this with video cam adaptors without much luck. The wide adaptors
to produce a fisheye look are the old Spiratone type and crop up on ebay
occasionally - I think Cambridge camera still sell them under their own
Cambo brand, if you've got the nerves of steel apparently needed to deal
with them. Rear thread is usually Series 7.
The video/digicam types simply produce a wider view on a standard lens,
usually with some slight barrel distortion, and simply vignette on a wide
angle without creating a nice fisheye effect. They are, after all, designed
to convert a standard 50ish lens to a 35ish wide, just as the supplementary
lenses were for the old Yashica Electro GT's and they do that well. Alas,
just too well corrected. (at least, all the ones I tried).
The 15mm Heliar is a stunner, as is the 21mm Skopar you won't regret
those. I looked at the 12mm yesterday for the first time - eeeeek! Saving,
saving........
