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.
