Used extensively for commercial work, short films, fashion and music video shoots. Leitax EF mounts, SIMMOD 80mm OD step up ring, SIMMOD caps and focus gears from FollowFocusGears.com. Declicked apertures. Recently inspected and serviced by an experienced lens technician in London. The optics are clean, clear and scratch free. No fungus, haze or separation. The bodies are in good condition. Helicoids are smooth. There is some dust inside the lenses, which is normal for the age of the lenses.
