This is a great lens both for stills and video, and is in beautiful condition. I had it modified for video use by a professional. The aperture has been de-clicked and it's now smooth and well-dampened. I also had installed a Leitax Canon EF mount. The mount feels like the lens was built with it. It also has focus gears. Of course, everything is reversible, and I have the parts to restore the aperture to its original condition. It comes with the Contax slip on lens cap as well as the Canon rear cap. The cinemod cost me about $150. The lens sells for between $750 and $1000 US, I'm asking for $800, and I think this is reasonable. Thanks.
