And this an ebay STEAL! A ZENITAR f2.8 16 MM full frame fisheye which as far as I can tell is a complete counterfeit of the Nikon version. A little softer at 2.8/4.0/and 5.6 but $99 and not a grand!
The intresting thing is that ALL of nikkor 16mm fishes are 8 elements cemented in 5 groups
The russian 16mm is 11 elements in 7 groups.
I understand that you're a Nikon guy, but don't say that Robert Hooke stole the design of the microscope from the japanese and discovered cells with it.
Wow, I'm impressed! Last week I was looking at a pic album about old cameras and i noticed a few of them in your collection. Must be hard to get'em, especially in good condition!
I like the little japanese one!
And I thought i was the only one to still own a Zenit... (And I think my grandpa still has his Zorki)
