152mm f/3.5 & 2.8 KOMURA experiences wanted

[Greg]

Am interested in members who have or have used either a f/3.5 or a f/2.8 152mm KOMURA. My old KOMURA brochure lists both lenses as covering the 4x5 format. Since no coverage stats in mm's are stated, I assume their coverage must be on the tight side. Would be used wide open for a 4x5 dry plate project in fall of 2020 that I have yet to commit to.

These lenses are very similar to the 150/2.8 and 135/3.5 Xenotar lenses, and 135/3.5 Planar. Both Komura lenses fully cover 4x5 without much movement. They do not increase image circle as you stop down, but edge sharpness does increase. I found that I could just cover a half-plate (4.25" x 5.5") with 152/2.8 Komura, so maybe 175mm of coverage.
