How many exotic non-Pentax lenses do you own ?

Nuij · 05-20-2017, 11:47 AM

A cyclop 85mm/1.5 and a Porst Color Reflex MC Auto 55mm 1.2. Both kind of collecting dust.

Cabessius · 05-20-2017, 12:03 PM

Seven different Helios 44, a 50mm Industar, a 135mm Fujita, two 28mm Sigma (Mini Wide I and II), a 200mm Topman, a 300mm Chinon, a Vivitar 70-210 and a Sigma 60-200.

None. Not a one.

**boriscleto** · 05-20-2017, 12:17 PM

Exotic? None. Commonplace? Many.

The most exotic lens I own is a Rokunar (Komine) 90mm F2.5 Macro with a KA mount...

Why not ?

I've plenty of non-Pentax lenses, but don't really know what counts as exotic. Perhaps the Carl Zeiss Biotar 58/ 2 17-blade preset. Originally Exakta mount, but CLA'ed and converted to K-mount by DCshooter. The Carl Zeiss Jena Pancolar 50/1.8 8-blade Lanthanum coated (radioactive). Or maybe the Carl Zeiss Jena Tessar 85/2.8 M42 mount? I'll let others determine what is "exotic" vs not common-place or just meh.

Perhaps my 1947 Kodak Anastigmat 50mm/3.5 that I've converted to K mount? 70 years old and still the best 50mm that I own.

Note to self: don't post on Pentax Forums on a Saturday evening (local time) after various glasses of wine when others will require supporting evidence. I hope these slightly inebriated uploads will be actually visible:

And here it is on a defunct K100D:

OP, define "exotic".

Dartmoor Dave, how did you manage this conversion? Also, it goes without saying, but does the fact that the lens carries its own shutter mechanism with it turn that defunct DSLR into a functioning one (e.g. in bulb mode), or is the Pentax body merely modelling?

By a quirk of fate the flange length of the 1940s vintage Kodak 35 models is close enough to K Mount that you can convert the lens and still get infinity focus. I simply disassembled a Kodak 35RF that was beyond repair and superglued a K mount to the lens. The easiest way to shoot with it is to set the lens's built-in shutter to T to lock it open and use the DSLR's shutter to take the photo. But when I want to get fancy I set the DSLR to a long exposure and use the lens's own leaf shutter to take the photo.
