Mamiya-6 V: A Folding Medium Format Rangefinder, Two Formats

The Mamiya-6 V is a folding-bellows medium format rangefinder built around a fixed 75mm f/3.5 Setagaya Koki Sekor lens, and its collapsible design means it packs down to something close to a pocketable footprint for a 6x6 shooter. That's not a small thing when you're used to carrying a boat anchor to get medium format negatives.

What sets this body apart is the dual format switch: shoot 6x6 square or 6x4.5, on the same 120 or 220 roll film, without swapping backs or bodies. That flexibility matters if you're the type who composes square for some subjects and wants the extra frame count and rectangular crop of 6x4.5 for others. The 75mm f/3.5 lens gives a standard field of view on the format, wide enough at f/3.5 for handheld work in decent light, and the rangefinder mechanism keeps focusing fast and quiet compared to a SLR's mirror slap.

There's no motor drive, no autofocus, no meter to lean on for some copies of this camera, just glass, film, and a folding mechanism that's genuinely clever engineering for its era. It's a camera built for people who want the negative size without the bulk, and who don't mind working a little slower to get there.

Who It's For

Travel photographers and documentary shooters who want medium format negatives without hauling a full SLR system will appreciate the folding bellows design, since the body collapses down for packing between shoots. Street photographers benefit from the rangefinder focusing system, which is quieter and faster to use at close range than a SLR's mirror mechanism. Anyone shooting portraits or landscapes who wants to switch between 6x6 square compositions and 6x4.5 rectangular crops on the same roll of 120 or 220 film gets that flexibility built into the body itself, without needing interchangeable backs. The fixed 75mm f/3.5 Sekor lens suits photographers who prefer working within one focal length than switching glass.

FAQ

What film formats does the Mamiya-6 V shoot?
The camera shoots both 6x6 square and 6x4.5 rectangular on the same 120 or 220 roll, toggled by an internal switch without changing backs or reloading.
Can you change the lens on the Mamiya-6 V?
No - the 75mm f/3.5 Setagaya Koki Sekor is fixed to the body. The focal length doesn't change.
Does the Mamiya-6 V have autofocus?
No. It's a rangefinder with manual focus via the coupled rangefinder patch; focusing is fast and mechanical.
How compact is the Mamiya-6 V when folded?
The folding bellows design collapses it to a pocket-sized footprint compared to other medium format cameras, though it still carries the weight that comes with medium format glass.
Is there a built-in light meter?
Some copies have no meter; check the specific unit. The camera is designed to work without one if needed.
What's the maximum aperture of the lens?
The Setagaya Koki Sekor opens to f/3.5, wide enough for handheld work in decent light without depending on fast film.
