Schneider Kreuznach Componon 300mm 5.6 Lens

Description

This lens is in good condition. It has a few spots and blemishes.  The iris aperture is smooth. Email with any questions. I have a 240mm also.
The Componon is a high-quality enlarging lens line. These models have been largely superseded by the Componon-S units, though a few Componon lenses are still manufactured today. Optical designs are 6 elements in 4 groups, and they are optimized for >10× enlargements.
