This is the CONTAX Vario-Sonnar T* 40-80/3.5 AEG. I am selling it as I am organizing my equipment. This lens has been around since the release of the first RTS. At the time, the standard zoom was generally 35-70, but I believe this is a rare lens that leans a bit more towards telephoto. I purchased it in beautiful condition at a used equipment fair several years ago. There are no noticeable scratches, but there are minor scratches and scuffs. It shows little signs of use. There is no mold or fogging in the lens, but there is some dust mixed in that does not affect shooting. Focus operation and linear zoom are smooth and have a good feel. The aperture operation has a click. The operation is good, and the photos in the 14th and 15th images are samples taken by connecting it to a full-frame mirrorless camera with a mount adapter. This lens is an AE specification, so when used with a CONTAX film camera, it will be in aperture priority mode. This lens does not support shutter priority or program modes. Accessories include lens caps (front and rear) and a protective filter. Since there is no option for the mount, I have listed it as EF mount, but it is a Yashica-Contax mount. Below is an excerpt of the specifications.
