80mm f/2.8 leaf shutter normal lens for Mamiya 645 autofocus systems

The Schneider-Kreuznach-designed optic in this lens is paired with a built-in leaf shutter, which means full flash sync at every speed the shutter supports, a significant practical advantage for any medium format shooter working with strobes. On the Mamiya 645DF, that sync capability translates directly into usable ambient-killing setups that focal plane bodies can't match without additional equipment. The 80mm focal length sits at roughly the normal perspective for the 645 format, making it a natural primary focal length for the system.

Autofocus on a leaf shutter medium format lens was a genuine engineering commitment when this was designed, and the Schneider glass backing it up brings optical credibility that the Mamiya system earned its reputation on. The 72mm filter thread accommodates a full range of circular polarizers and ND glass. For medium format shooters building a working kit around the 645DF platform, this lens covers the most-reached-for focal length with the added sync flexibility that makes location work with artificial light practical.

Who It's For

Commercial and portrait photographers shooting with Mamiya 645DF bodies will find the leaf shutter's full flash sync capability essential for strobe-lit location work and studio setups where precise exposure control matters. Wedding photographers working in mixed or outdoor light can balance ambient and fill flash in ways a focal plane shutter body cannot. Photographers moving into medium format who want a single normal-perspective autofocus lens to anchor a kit will find 80mm on 645 format covers that role directly. The Schneider-Kreuznach optical design brings additional confidence for anyone prioritizing image quality at f/2.8.

FAQ

What's the advantage of a leaf shutter on a medium format lens?
Full flash sync at every shutter speed - the 645DF syncs flash across the entire range without needing a focal plane body's sync speed limitation. That makes strobes practical for ambient-killing on location without radio triggers or fill-flash workarounds.
Is this lens autofocus?
Yes. Autofocus on a leaf shutter medium format lens required deliberate engineering, and the Schneider optics backing it justify the system's reputation.
What focal length is 80mm in the 645 format?
It's the normal focal length for Mamiya 645, roughly equivalent to 50mm on full-frame in terms of field of view and subject perspective.
What filter size does this lens accept?
72mm. That opens up a full range of circular polarizers and ND glass without specialty step rings.
Who designed the optics?
Schneider-Kreuznach. The glass carries the optical credibility the Mamiya 645 system built its reputation on.
What Mamiya body does this work with?
The Mamiya 645DF autofocus system. Confirm your body accepts 645 mount autofocus lenses before purchase.
