Mamiya's standard portrait lens for the RZ67 system — a medium format classic for studio portraiture.
The Mamiya Sekor RZ 127mm f/3.5 W is a standard portrait lens for the Mamiya RZ67 medium format system. On the 6x7 format, 127mm provides approximately a 63mm equivalent perspective — slightly wider than the traditional portrait focal length, well-suited to environmental portraits and three-quarter compositions. The W designation indicates a wide-angle barrel design.
Optical performance is very good. Sharpness is excellent when stopped down, with a pleasant rendering characteristic of the Mamiya Sekor series. The large 6x7 negative combined with f/3.5 produces significant depth of field separation. Bokeh is smooth and flattering for portraits. The built-in leaf shutter enables flash synchronisation at all speeds — critical for studio work.
Mamiya RZ mount with integrated leaf shutter. Filter thread is 77mm. Weight is approximately 620 grams. Build quality is robust — the RZ system was designed for professional studio use. The leaf shutter mechanism adds weight but provides invaluable flash sync capability. Manual focus with the RZ67's bellows-style focusing system on the camera body.
Available on the used market at reasonable prices for medium format glass. Check leaf shutter operation across all speeds and clean optics. The RZ67 system is heavy and studio-oriented but produces outstanding images. Essential lens for RZ67 portrait photographers. The 180mm f/4.5 offers a longer perspective for headshot-style portraiture.
