>>3996574They don't make it anymore, they don't make the camera it was for anymore either. Maybe you're just wacky enough to want to use the lens on a different body, maybe you just really like the way the Carl Zeiss Contax 21mm looked when you shot it in the 90s and want to use it with your new full frame mirrorless. You're gonna pay for a shitty adapter that forces an autofocus lens to be manual focus or you're gonna pay for a full-on conversion. Regardless, you're gonna pay.
