Perceval Posted September 10, 2023 Share #1  Posted September 10, 2023 Advertisement (gone after registration) I have a screw thread 28mm f3.5 lens that looks exactly like Kobalux/Pasoptik/Avenon/Bower branded lenses of the same specification but it has no maker's name (and no serial number). It feels substantial and performs excellently, with extremely good resolution. Single-coated, it has a little lest contract that moderns lenses. My guess is that it is part of a pre-production test run ?

frame-it Posted September 10, 2023 Share #3 Â Posted September 10, 2023 Maybe a test model for the V2 version. "Originally made in 1981 in chrome with distinctive round focusing tab, a six-blade diaphragm and minimal focus to 1 meter. The second generation, or "M-series", was sold in black with a silver rim. It has a crescent-shaped focusing tab, an eight-blade diaphragm, grip tabs on the aperture ring and minimal focus to 0.75 meter." Quote Link to post Share on other sites More sharing options...
PMCK Posted September 11, 2023 Share #4  Posted September 11, 2023 Thanks, frame-it. Six-blade diaphragm, 1 metre closest focus, matt silver/chrome finish but depth-of-field scale is on polished chrome. Unusual to have a capital F in the max aperture description.
