※Please treat this item as junk. This is a K/L 75mm F3.5 L, a semi-wide angle prime lens for the Mamiya RB67. [Appearance] It is clean with no noticeable scratches or stains. Please check the images. [Operation] No problems. The lens shutter, aperture, etc. are all working smoothly. The floating mechanism also moves smoothly. [Optics] There is slight clouding on the periphery of the lens and fine, granular balsam separation throughout. When I actually used it, it didn't seem to cause any particular problems. It seemed to produce good color even with positive film. ※Due to the issues mentioned, please consider this item as "junk." Please purchase with the understanding that it is being sold as such.
