Showcase Vivitar 24mm f/2 (Kiron-made in Nikon F mount)

Nov 13, 2012
The Netherlands
I'm getting more and more frustrated that Zeiss nor Voigtländer (Cosina) make a nice MF 28mm for Sony E-mount (full-frame), so I'm thinking of getting a Zeiss Loxia 2.4/25 when a good deal comes along. To find out if that focal length works for me, I took the only 24mm I have, an old Vivitar 2/24 in Nikon F mount, out for a spin. Its serial number starts with 22 so Kiron supposedly is the manufacturer. As so often with Kiron lenses, the diaphragm leaves are oily, allowing the aperture to close down to around f/8. Even at f/8 image quality isn't all that great, but it works surprisingly well in B&W.

These came out very nice in B&W!
I have a Kiron-made 28mm f/2 that succumbed to stuck oily blades. An issue with most Kiron/Kino lenses. I ambitiously tried to disassemble it after success with Kiron lenses previously, but this one confounded me with its odd construction. It now sits in a box somewhere. ;)

I have a Kiron-branded 24/2 lense that I got off of Ebay, it's an impressive piece of glass, unfortunately it turned out to have a crooked element or something similar, I didn't know enough about photography at the time to catch the problem in a timely manner. These lenses are hard to find, the various 28/2 versions were far more common, I have several of those.

Sometimes you can free the blades up a bit by dropping a little 99% pure alcohol on 'em, while moving the aperture back and forth.
