The Mamiya 7 and Mamiya 6 are both medium format rangefinder cameras with excellent reputations, but they use different negative shapes. The Mamiya 7 shoots 6×7 frames and has interchangeable lenses on a fixed body, while the Mamiya 6 shoots square 6×6 frames and uses a folding lens design. Choose the 7 for the rectangular format and the 6 for square compositions and a very compact folded body.
What Each Camera Is For
The Mamiya 6 is a compact folding rangefinder. Its lens collapses into the body, which makes it small enough for a coat pocket or a small bag. It suits street, travel and portrait work with a square frame.
The Mamiya 7 is a later camera in the same spirit, with a non-folding body and a larger 6×7 frame. It is also a favorite for landscape and travel photographers who want big negatives without carrying an SLR.
Key Differences
| Trait | Mamiya 6 | Mamiya 7 |
|---|---|---|
| Frame | 6×6 square | 6×7 rectangular |
| Body design | Folding lens | Fixed body |
| Pocketability | Better when folded | Larger |
| Frames per 120 roll | More | Fewer |
| Cropping | Often cropped in print | Closer to common print ratios |
Practical Considerations
- Composition: Square is a distinctive style, while 6×7 fits common print sizes with little cropping.
- Portability: The Mamiya 6 packs smaller, though the extra size of the 7 is still modest for medium format.
- Lens choice: Check the lens range of each system, since options are limited and not interchangeable between the two.
- Condition: Folding mechanisms and older electronics need careful checking on used bodies.
How to Choose
- Think about whether you enjoy square framing or prefer a rectangle.
- Decide if a pocketable folded body matters for your daily carry.
- Look at current used listings and compare what lenses are included.
- Check the focus patch, shutter, light seals and film advance.
- Ask for sample images, and request a return window where possible.
Handling Notes
Both cameras use a rangefinder system, which means quiet shooting and no mirror shake. A shutter speed near 1/60 can still be workable handheld for careful shooters, and 1/125 or faster is a safer first guess. On the Mamiya 6, remember to unlock and extend the lens before shooting. On either camera, confirm the battery requirement before a trip, since older models rely on batteries for the shutter.
FAQ
Do the two share lenses?
No. Their lenses are designed for each system, so you cannot move lenses between them.
Which one holds more detail?
The Mamiya 7 has a larger negative area, which can help in large prints. Both produce excellent detail with good technique.
The Short Version
Choose the Mamiya 6 for a square frame and a compact folding design. Choose the Mamiya 7 for a larger 6×7 negative and a more conventional print shape. Verify specs on trusted sources before you buy.
