Anyone have any experience with Komura lenses

[xkaes]

There are the Komura lenses that I can find -- supposedly -- for 4x5 cameras. There may be others.

75mm f/6.3, filter size 72mm
152mm f/2.8, filter size 77mm
300mm f/5.0, filter size 67mm
400mm f/6.3, filter size 67mm
500mm f/7.0, filter size 77mm

I have two really huge Komura 4x5 lenses, in Seiko Shutters. The 75mm and the 90mm. I also have the Uber BEEG 90mm Lens Hood. Looks impressive, looking forward to testing it as I have time. Look good on Plaubel Peco Profia 4x5s.

I have had the 210 f/6.3 "Commercial" for decades. Copal 1. Lots of coverage for 4x5, plenty sharp for me. Coating my be single; I'm not sure. Purchased used c. 1980.

Good news/bad news about the 75mm:

Good - it has quite a long flange focal length, around 100mm, so you might not need a recessed lens board even if you do with other 75s.

Bad - it's very tight on coverage (image circle 158mm) for 4x5.

Both according to the old spec pages you can find on the web.

Komura made some stand-out lenses for 35mm cameras, too, like the Komura Sankyo Kohki 85mm f/1.4 and a 100mm f1.8. In my exploration into their lenses, I ran across them. These two were early pre-set which cam in various mounts. And here's something I never heard before:

"In the 1970s, the company developed the Komura Unidapter System that allowed their 35mm interchangeable lenses to mount to "practically all Japanese-made and a number of European-made reflexes - as well as 16mm cine cameras with C mount" Komura Unidapter adapters known to exist include Canon FL, Exakta, M42 (Pentax/Practica), Miranda Sensorex, Nikon F, Minolta, Ricoh Singlex, Petri, and Topcon D-1."

The 152mm f2.8 Komura




has gone the same market way as the 150mm f2.8 Xenotar, 135mm f3.5 Xenotar, 135mm f3.5 Planar... 6" f2.5 Aero Ektar.... remarkable $ (four figures U$D) for what once were un-desierable large aperture lenses that "just" image circle enough for 4x5.. Much about the current fashion thing amoung those new to sheet film carrying on their digital/roll film ways, values, habits...

Komura was know for their version of Kodak Commercial Ektar that appeared with other brands doing similar after Kodak got out of the LF lens business..

There was a time not too long ago when Komura, Yamasaki Optical and other lesser known view camera lens folks where considered greatly lesser to the "big four". That has changed lots in recent times..

IMO, Komura like other lens brands will have plus/minus trade-offs.. There is no idea magical_miracle lens, just the lens that has some chance or ability to meet the needs of specific image goals...
