Fisheye for 8x10? What is the widest ever?

FWIW fisheye lenses are extensively used underwater where the lack of straight lines and unfamiliar subject matter often 'mask' the fact that the view is distorted. Their ability to include a great FoV in limited and low visibility is a boon in many areas. It has always been tempting to try a modified MF fisheye underwater but the custom build costs are pretty prohibitive.

There are (rare) underwater housings for the Pentax 67 and 35mm fisheye. Expensive, but less than a custom build!

(- and e.g. Gates housings for the 38mm Biogon SWC)

Re: Fisheyes; to add both a philistine and sacrilegious git angle: Anyone ever looked into fisheye adapters (auxiliary lenses) to add to any ordinary 8x10 lens? Resolution at 8x10" surely can't be the most critical parameter.... I have in the past used a cheap Olympus C-180 teleconverter on a 450mm Fujinon-C (=720mm) with quite impressive results (on 5x7" at least).....

So just acquired a 35mm f/4.5 FISH-EYE TAKUMAR 6x7 for my Pentax 67II. Asking price was just too much of a bargain to pass up on. Was a bit worried about the less than detailed description of its condition, but it arrived yesterday and cosmetically is in Mint- condition. Shot a test 120 roll today and mechanically works just fine. In the near future will somehow mount it on my Sinar and make a full image test shot. Best guess is that it will over cover the 4x5 format, but definitely will give me a circular fish eye image on my 8x10, all be it on the smallish scale. Will post details once I figure out how to mount the lens on my 8x10.

Cool. Will look forward to actual results. Don't disappoint us.

+1. I have put off adapting/testing mine due to having other things to do. I don't think it'll "cover" 4x5. I am personally hoping the circular image happens in a 4x4 inch area. The photos I have seen from the Mamiya 37mm does so. I can't imagine the two lenses would be much different?
