Premium Member Daniel J. Fox Posted November 3, 2025 Premium Member Posted November 3, 2025 Optex rehoused Canon FD 20-35mm T3.5 cinema zoom lens Mitchell BNCR mount A very rare compact cinema zoom lens, dating from the 1980s, used to expand Canon K35 lens sets. The optics are bright, clear and clean and the mechanics, while of the time are excellent and smooth. Recently serviced by Duclos lenses in the US. The lens was dis-assembled completely, all components cleaned. Sprayed and baked worn parts. The zoom, focus and iris all re-lubed. Cleaned and aligned accessible optics. Re-collimated. The lens rehousing has 77mm front filter threads. I added a Simmod knurled 77mm to 80mm front step-up ring and custom push on lens cap. Can be adapted for use on any mirrorless mount camera or Canon EF. Comes complete with front and rear caps. Optics presently cover a S35 sensor. It might be possible to increase the coverage by removing the rear cowl. Price: £4000 Ships from the UK at cost (buyer pays all shipping and necessary insurance).
