This is a sale of a Fuji SF ( soft focus ) 180mm /f 5.6 lens mounted in a Copal shutter and on a Linhof board. There is a red dot focus disc mounted in the lens. The disks are used to control the amount of diffusion. No disk - maximum diffusion, yellow disk - moderate diffusion, red disk - more subtle diffusion.
The shutter works fine. The lens itself is totally beautiful with normal sign of use. No issues.
