Mamiya-Sekor 50mm f4.5 for Mamiya RB67 hand grip with only the most minorThis Mamiya Sekor 50mm f4. 5 for Mamiya RB67 is in excellent cosmetic condition, with only minor paint and finish wear. There is a very light cleaning mark near the edge of the front element; the glass is otherwise clean and clear. Slightly stiff aperture and FLE rings, good diaphragm blades, accurate shutter speeds throughout range. Not perfect, but still an excellent (and fully functional) wide angle lens for the RB.
