I picked up a lens at an estate sale and I wondered if anyone had any experience with this line or this lens:

Komuranon-S
6 Elements in 4 Groups
f75/5.6

The lens appears unused/mint, the inner box was sealed and the and there is an old price sticker for $89.99 on the box. I bought that and an (apparently) unused El-Nikkor 50mm f4 very cheap.

Is it an enlarging lens?

Komura made aftermarket lenses for Bronica S and EC series cameras and Nikon in the 1960s. They probably OEM'ed some other brands over the years. They also made some LF lenses. I think today they make high-end video lenses.

Seems the LF 75mm was a F/6.3. But that list doesn't cover all the Komuras. I got a 210mm F/6.3 and it's not on the list either.

Is it an enlarging lens?


Definitely an enlarging lens.
