Mamiya Sekor Z 250mm f/4.5 Lens for RZ67 System Review

The Mamiya Sekor Z 250mm f/4.5 is a medium telephoto prime designed for the Mamiya RZ67 medium format system. At 250mm, it offers a field of view roughly equivalent to a 140mm lens on 35mm, making it well suited for portraiture, product work, and distant subjects where a longer reach is needed without moving into ultra-telephoto territory. The f/4.5 maximum aperture is typical for lenses of this focal length in the RZ67 lineup, balancing size and optical performance with practical portability for studio and field work.

This particular listing is a used copy graded as "Bargain" by KEH, indicating visible wear or cosmetic blemishes that do not affect optical performance. At this price point, it represents an accessible entry into the RZ67 telephoto range for shooters already invested in the system. The RZ67 platform remains popular among film photographers and rental houses for its modular design and exceptional image quality, and lenses like the 250mm continue to find steady use in both commercial and fine art contexts.
