Personally collected and refined over a 5 year period from fellow professionals in the UK and Europe. Beautiful organic image rendering with unique vintage Zeiss character. 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. Suitable for all EF mount full frame 35mm/large format and Vista Vision cameras (Arri Alexa LF, Sony Venice/FX9/FX6/FX3/A7SIII, RED V-Raptor) All have been used with a range of adapters (including various Metabones Speedboosters) Includes custom cut foam peli style hard case Incredibly similar to Zeiss Super Speeds (same glass, coating, general design). The Contax Zeiss have the advantage of being smaller bodied and more light-weight, making them a great choice when looking to decrease the overall weight of your camera set up, for travel, run and gun or for use with Gimbals.
