I'll let you decide that yourself. Here's a comparison I did several
months ago between the Arsat and the F-Distagon. Both are 30mm fisheye
lenses for medium format.

Thanks for telling me about that Soligor.

Jim,
How is the Arsat lens? I've heard that it's very sharp and contrasty.
As far as using a fisheye on medium format, I have an old Soligor
fisheye converter lens with a .15 conversion factor. This is the high
dollar one with its own diaphragm that's adjustable. I have several
adapters for it including bay 1 & bay 3 adapters for use on rollei twin
lenses, or my Yashica mat 124G. I first mount the lens on the viewing
lens, focus, and then transfer the lens to the taking lens and shoot.
With the conversion factor of .15, the 75mm camera lens becomes an
11.25.. lens! This is a circular image fisheye. I've used it on a 90mm
Summicron to get a nearly full frame 13.5mm. A 100mm gives 15mm.
These are fun lenses if you can find them. They were made under several
manufacturer's names, but were all high quality construction with
adjustable apertures and a lens size/f-stop conversion scale so you
could figure effective aperture settings for pretty much any lens that
you mounted the conversion lens on to.
