Mamiya Sekor Z 110mm f/2.8 Lens for RZ67 System Review

The Mamiya Sekor Z 110mm f/2.8 is a medium telephoto lens designed for the Mamiya RZ67 system, a modular medium format camera beloved by portrait and studio photographers. With a 77mm filter thread and a fast f/2.8 maximum aperture, this lens delivers shallow depth of field and strong low-light performance on the RZ67's large 6x7cm frame. Its focal length translates to roughly 55mm in 35mm equivalent terms, making it a natural choice for portraiture, product work, and detail shots where compression and subject isolation matter.

Available primarily on the used market through outlets like KEH, condition grades range from bargain to excellent, with pricing around $626 for excellent-grade copies. The Sekor Z line is known for sharp optics and solid build quality, though the RZ67 system as a whole is heavy and mechanical, requiring commitment to the format. This lens suits photographers already invested in the RZ67 ecosystem or those entering medium format film work who prioritize image quality and manual control over portability.
