Mamiya APO-Sekor Z 210mm f/4.5 Lens for RZ67 System Review

The Mamiya APO-Sekor Z 210mm f/4.5 is a medium telephoto lens designed for the Mamiya RZ67 medium format system. With its 210mm focal length on the 6x7 format, it delivers a field of view roughly equivalent to a 105mm lens on 35mm film, making it a go-to choice for portrait work, product photography, and selective landscape compositions where compression and subject isolation are priorities. The APO designation indicates apochromatic correction for chromatic aberration, a meaningful advantage when working with the large film area and high resolution demands of medium format.

As a used lens from KEH, this copy is graded as bargain condition, which typically means visible cosmetic wear but functional optics. The 77mm filter thread is a common size, simplifying filter use across other gear. For RZ67 shooters looking to expand beyond standard lenses without breaking the bank, this offers the reach and optical quality expected from Mamiya's professional Z-series glass, provided you're comfortable with the cosmetic condition and the manual focus workflow inherent to the system.
