Most Mamiya medium-format cameras are systems, not single objects — a body, a film back, a finder and a lens, each with its own value. We identify the system first, whether it is an RB67, an RZ67, a 645, a C-series twin-lens or a Mamiya 6 or 7, then assess every part you send.
Bodies, backs, finders and lenses, working or not. Written valuation. Free insured postage. Paid in 72 hours.
Mamiya built several distinct medium-format systems, and knowing which one you have is the first step to a sensible valuation. Some shoot a 6×4.5cm frame, others a larger 6×7cm negative; some are studio SLRs with rotating backs, others are twin-lens reflex cameras or compact rangefinders. You do not need to identify yours precisely before contacting us — that is our job — but the table below shows how the main families differ.
| System | Type | Format & notes |
|---|---|---|
| Mamiya 645 | Medium-format SLR | 6×4.5 on 120; the most compact and economical of the range |
| Mamiya RB67 | Medium-format SLR | 6×7 with a rotating back; fully mechanical, no battery needed |
| Mamiya RZ67 | Medium-format SLR | 6×7 with a rotating back; electronic shutter control |
| C-series (C220, C330…) | Twin-lens reflex | 6×6; unusual in taking interchangeable lens pairs |
| Mamiya 6 | Rangefinder | 6×6 on 120; collapsible mount, interchangeable lenses |
| Mamiya 7 | Rangefinder | 6×7 on 120; interchangeable lenses |
We do not describe any particular model as automatically rare or valuable — that depends on the specific example and how complete it is. What we can say is that identifying the system, the parts and the condition precisely is the only honest basis for a figure.
The RB67, RZ67 and 645 are modular, which is a real advantage when you sell: each component is assessed on its own, so an outfit with several backs and lenses is valued piece by piece rather than as a single lump. If you are missing a finder or a back, that is fine — we simply value what you send.
The core mechanism. On the RB67 it is fully mechanical; on the RZ67 it is electronic and tested for shutter and metering function.
Rotating backs and 120/220 inserts carry their own value. Dark slides, seals and film counters are checked; spare backs are worth sending.
Waist-level and prism finders, metered or plain. The screen and finder optics are assessed for clarity and any fungus or haze.
Each lens has its own leaf shutter on the SLR systems. Optical condition and shutter operation are assessed lens by lens.
Haze, fungus, cleaning marks and scratches in each lens all affect the result. We describe the glass precisely and assess every lens you send, spare lenses included.
Leaf shutters in the lenses can grow slow or sticky, and the RZ67 depends on working electronics. We test what we can and record what each shutter and body actually does.
Foam seals perish with age and film backs can leak or misfire. The state of seals, dark slides and film counters is noted for each back received.
Covering, finish and mechanical feel, plus which backs, finders, lenses, caps, cases and papers are present. Honest wear is simply described accurately.
Please note that photographs can help identify the system and condition, but a physical inspection may be needed before a final valuation or offer — shutter accuracy, light seals and electronic function are hard to judge from images alone. And please do not attempt invasive cleaning or repair before valuation; original condition can be useful to assess.
If your Mamiya is one part of a larger holding, the broader sell vintage cameras & lenses guide explains how we handle mixed outfits. For other medium-format systems, see sell Hasselblad cameras and, for twin-lens reflex cameras, sell Rolleiflex cameras.
Fair Vintage is an independent vintage and collectables buyer and is not affiliated with, authorised by or endorsed by any current holder of the Mamiya trademark. Names are used here only to describe the cameras and lenses we buy.
Tell us roughly what you have — "an RB67 with two backs and three lenses" is plenty. We email a free prepaid, tracked and insured label the same working day.
Wrap each body, back, finder and lens separately, include any dark slides and papers, and use a sturdy box. Your parcel is insured to £5,000 from the first courier scan.
We email a unique parcel code and your opening time. Your parcel is opened on camera and photographed before a specialist identifies each part.
Each body, back, finder and lens itemised — model, condition and figure, in pounds. Accept what you want to sell; the rest comes back free. Payment within 72 hours, or we add 3%.
If your question isn't here, call us on 01234 815116 or email support@fairvintage.co.uk. We respond within one working day.

Send a note of the bodies, backs, finders and lenses you have; if you are not sure of the model, a photo of the body and any name plates is usually enough for us to identify it.
Both are 6×7 modular medium-format cameras with a rotating back, but the RB67 is a fully mechanical camera that works without a battery, while the RZ67 adds electronic shutter control and needs power for its full range of speeds. From a valuation point of view the distinction matters because the RZ67's electronics are part of what we test. Tell us which you have, or photograph the body and back and we will identify it.
It helps, but missing parts do not stop us buying. The RB67, RZ67 and 645 are modular — a complete camera is a body, a film back or insert, a finder and a lens — and each part carries its own value, so send whatever you have, including spares. If your outfit is missing a finder or a back, we still value the parts you send; we simply note what is present rather than assuming a complete system.
Yes. The C-series twin-lens reflex cameras are unusual in taking interchangeable lens pairs, so any extra lenses are worth sending. The Mamiya 6 and Mamiya 7 are medium-format rangefinders with their own lenses, valued as a system with any additional lenses and finders. As always, the model, the lenses and the condition together decide the figure, and we identify each item before valuing it.
Yes, we assess non-working cameras on their merits. Sticky leaf shutters in the lenses, foam light seals that have perished, and electronic faults on the RZ67 are all common on stored cameras, and none automatically rules a Mamiya out. We describe the faults in writing and reflect them in the figure. Please do not attempt invasive cleaning or repair before valuation; original condition can be useful to assess.
