Industar-69 Lens (28mm f2.8)
I purchased this oddity off Amazon for less than $30 USD. The package arrived neatly packaged in a stamped box from the Ukrain. Much is written about hacking this lens for use on mirror-less digital cameras by filing down a post. I had none of that —I just unscrewed the post and it works fine now as a closeup lens and sees to infinity. I’ll follow up with a few comments with it mounted to an Oly OMD EM-5, but for now I had fun with it on my screw-mount Bessa-L.
The Industar-69 was originally mounted to a Chaika (“Seagull”) half frame (18-24mm) camera by way of a 39-SM thread. On the larger framed Bessa-L, images are vignetted. The Industar-69 is a Tessar lens variant, with 4 lenses in 3 groups. Wide open it is soft as polenta and reminds me of cheapo Russian cameras like the Smena 8.
Here’s some images. The indoor images were shot wide open at 2.8. The remaining images f5.6 to f16. I didn’t take any notes. I used Kodak 400 Portra film.
