Mamiya RZ67's standard portrait lens at f/2.8

The 110mm focal length sits at roughly normal on 6x7 medium format, which means it renders perspective the way your eye does without any of the distortion that comes from going wider or longer. At f/2.8, it gives you meaningful light-gathering capability for a medium format lens of this size, letting you work in lower light or separate a subject from the background with the kind of fall-off that only large-format glass can produce.

The 77mm filter thread is worth noting practically: it accepts standard polarizers and graduated NDs without proprietary adapter headaches. Built for the RZ67 system, this lens works with the camera's rotating back, so you can switch between portrait and landscape orientation without repositioning your tripod head, a genuine workflow advantage on location. The RZ67 system was designed around studio-grade mechanical precision, and lenses like this 110mm W reflect that lineage.

For medium format shooters who want a single all-purpose lens that covers portraiture, product work, and environmental shooting, the 110mm f/2.8 W is the obvious anchor of any RZ67 kit. It's the lens you leave on the camera.

Who It's For

Portrait photographers shooting on the RZ67 will find the 110mm focal length ideal for head-and-shoulders to three-quarter compositions without the perspective compression of a longer lens. Studio product shooters benefit from the f/2.8 maximum aperture when precise depth control matters more than depth of field. Travel and documentary photographers who want a single medium format lens for varied work can rely on this focal length to cover most situations. Film shooters building out a RZ67 system will recognize this as the natural starting point.

FAQ

What focal length is the 110mm on a full-frame equivalent?
It's roughly a 50mm equivalent on 35mm film, which is normal perspective, but you're working with the large negatives and tonality of medium format.
Can I use standard 77mm filters on this lens?
Yes - the 77mm thread accepts any standard polarizer, ND filter, or graduated filter without adapters.
How does the f/2.8 aperture perform compared to other medium format portrait lenses?
f/2.8 is fast for medium format and gives you genuine subject separation and shallow depth of field, though it's not as extreme as you'd get on 35mm glass at equivalent speeds.
Does this lens work with the RZ67's rotating back?
It's built for the RZ67 system, so yes - you can flip between portrait and landscape orientation without moving your tripod or head.
Is the 110mm truly a one-lens solution for RZ67 work?
For portraiture, environmental shooting, and general-purpose work, yes - it delivers normal perspective without distortion and enough light-gathering for studio or daylight work.
What's the optical construction of the Sekor Z 110mm?
Mamiya didn't publish a full lens formula for this model, but the Z designation indicates it's optimized for the RZ67's mechanical and optical standards.
