I am interested in Olympus Pen F/FT film camera system (APS-C on 35mm film).
My largest concern is availability of wide angle lenses. I would like to have something like 28mm in 35mm equivalent, and the only (and the widest) available native option is 20mm/3.5 (28mm equivalent), which does not survive very well until this day due to haze/de-lamination on majority of ebay samples, despite it's relatively high cost.
I ether will have to disassemble and re-glue the lens - which is a challenge on it's own or adopt 3rd party or more modern Olympus lens.
Any suggestions on which path is most feasible to get 20mm or shorter lenses on Olympus PEN F/FT film camera? I would prefer to avoid full-frame 35mm lenses with huge flange focal distance, as it will be extremely bulky.
