Amazing  collectable condition lenses for photography or video usage.

I can offer soft adapted to either, Canon/Sony.Fuji.

I can supply a custom case,  but that will make the shipping prohibitive. Best to get a case in your home country.

I am available for Zoom meeting so you can inspect the lens. This also avoids scammers.
