Panagor 0.15x fisheye B50 Mount

Has anybody heard of this before? Or dare I say used one?

If yes, how does it stack up against the other filter screw on

fisheye adapters (i.e. ProOptic/Adorama)?

Thanks,

Stu :)

PS. Yes I know that fisheye adapters are crass and genrally spitted

apon. But I miss my 14mm and 20mm lenses in 35mm format. A 38mm

Biogon is out of my budget and I hear that putting and using an Arsat

30mm f3.5 on a Hasselblad is not fun.

I think the reason you'll find fisheye adaptors not commonly used with MF is that you lose the quality you gain by switching to MF in the first place. Sort of like putting a Uhaul trailer on a race car.

I assume the 14mm and 20mm lenses you mention are rectilinear- as is the Biogon? In other words, not much of a comparison to a fisheye or fisheye adaptor.
