Mamiya 90mm f/3.8 Sekor: the RB67's workhorse normal lens.
The 90mm focal length puts you in familiar territory for medium format portrait and documentary work, and the f/3.8 maximum aperture gives you enough light-gathering to shoot in mixed or low-contrast light without forcing you to a tripod every time. On an RB67 body, this is the lens you reach for when you want a natural angle of view without the compression of a longer telephoto or the exaggeration of a wide.
Mamiya's Sekor lineup was built to match the RB67's reputation as a studio and location workhorse. The optics are designed for the demands of medium format film, where resolving power and rendering across the frame matter at print sizes that expose every weakness. Portrait photographers will find the 90mm focal length keeps working distances comfortable and facial proportions natural. Documentary and street photographers working with the RB67 get a lens that reads as neither wide nor tight, letting the subject fill the frame without the geometry of a wider lens distorting the scene.
For the medium format film photographer already invested in the RB67 system, this is the lens that earns regular rotation. It covers the everyday range that a 50mm does for 35mm shooters, and it does it with the negative size that makes medium format worth the effort in the first place.
Who It's For
Portrait photographers working in studio or on location with the RB67 will find the 90mm focal length keeps the lens-to-subject distance natural without pulling in distracting background. Documentary and editorial shooters who want a neutral angle of view on medium format, without wide-angle distortion, get exactly that at f/3.8. Film photographers building out an RB67 kit who need a single do-most lens will find the 90mm covers the widest range of assignments. Anyone coming to medium format from 35mm who wants a familiar perspective translated to a larger negative should start here.

FAQ
- What focal length is the 90mm Sekor on an RB67?
- 90mm is the normal lens for the RB67 system, giving you a natural angle of view that sits between wide and telephoto. It's the focal length most RB67 shooters reach for first.
- Is the f/3.8 aperture fast enough for hand-holding in low light?
- f/3.8 gives you enough light to shoot hand-held in mixed or low-contrast conditions without forcing a tripod every time. It's not blazing fast, but it's workable for location and documentary work.
- How does this lens render compared to other RB67 Sekor lenses?
- The Sekor lineup was built to the same optical standards as the RB67 body itself, designed for medium format resolving power and consistent rendering across the frame. The 90mm handles portrait and documentary work with natural proportions and working distances.
- Will this lens work on other Mamiya medium format bodies?
- No, this is a Mamiya RB67 mount lens. It will not fit other Mamiya systems like the 645 or 645 Pro. Check your mount type before buying.
- What kind of work is the 90mm best suited for?
- Portrait, documentary, and everyday shooting where you need a lens that reads as neutral in terms of perspective. It's comfortable for people work and keeps subjects naturally proportioned in the frame.
- Is this a true normal lens for medium format?
- Yes. On the RB67, 90mm functions as the system's standard, everyday lens the same way a 50mm works on 35mm cameras.
