Mamiya Sekor Z 180mm f/4.5 W Lens for RZ67 System {77}

Mamiya Sekor Z 180mm f/4.5 W: medium-format telephoto built for the RZ67.

The 180mm focal length on the 6x7 format delivers the kind of subject-to-background compression that portrait and editorial photographers specifically seek out. At f/4.5, you get enough separation to isolate a subject against a thrown background without the focus-plane anxiety that comes with faster glass on a large-format system. The 77mm filter thread is a practical bonus, it matches common filter sets and keeps your workflow consistent across lenses.

The Sekor Z designation places this lens firmly in the RZ67 system, meaning it's designed around the demands of medium-format studio and location work. For photographers already invested in the RZ67 platform, this lens slots into a focal length range that shorter system lenses don't cover and longer ones overshoot for most portrait and figure work. The optical formula rewards careful technique: slow down, use a tripod, and the 6x7 negative will show you what medium format actually means.

Who It's For

Portrait photographers shooting on film who want subject compression without extreme lens speed will find the 180mm f/4.5 sits in a practical working range on 6x7 format. Fashion and editorial shooters who need a reliable telephoto for head-and-shoulders framing at modest working distances can use it without fighting the lens. Still-life and product photographers building out a dedicated RZ67 kit benefit from the 77mm filter thread, which aligns with polarizers and graduated ND filters already in their bag.
