For sale is a vintage 135mm Carl Zeiss Sonar lens.

It is in a used but good state, and fully functioning. As this is an old lens, it is normal to have scratches and on the lens body, some dust between the lens elements, and maybe some cleaning marks on the front element. If any not specified, it does not present obvious scratched, fungus and/or mist.

It comes as presented in the pictures, with orignial leather case, and (probably) aftermarket lens mount front element cap. The aperture and stop down aperture button are oil free and work as designed.

This lens has a weird aperture control design, that closes down the aperture as you change the focus. At first i thought that it is deffective, but it is designed to work this way.

Before sale i always inspect the item for any defects, and try out their function as best as i can. If you need more photos or information do not hesitate to contact me. 

This is a private sale, so i will not offer any warranty
