Mamiya M645, a medium-format single-lens reflex (SLR) camera that left its mark on photography.
Mamiya M645: A Versatile Medium-Format SLR
Introduction:
- The Mamiya M645, introduced in 1975, was the first in a series of 4.5×6 cm SLRs made by Mamiya.
- Unlike its larger 6×7 cm siblings, the M645 doesn't have bellows but relies on helical focusing in its lenses.
- This camera was designed for serious photographers who wanted the flexibility of medium-format film without the bulk of a 6×7 system.
Build and Ergonomics:
- The M645 has a robust build, with a metal chassis and a leatherette-covered exterior.
- It feels substantial in hand, striking a balance between sturdiness and portability.
- The ergonomic grip allows comfortable handling during extended shooting sessions.
Film Format and Inserts:
- The M645 captures 15 frames on a standard 120 roll film, producing 4.5×6 cm negatives.
- Instead of a magazine back, it uses pre-loadable film inserts. While this simplifies loading, mid-roll changes are not possible.
- The lack of a magazine also means that the M645 is lighter and more compact than some other medium-format cameras.
Electronic Focal Plane Shutter:
- The heart of the M645 is its electronically controlled cloth focal plane shutter.
- Shutter speeds range from 8 seconds to 1/500 second in one-stop increments.
- Mirror lockup is available for vibration-free exposures, especially when using longer lenses or slow shutter speeds.
- Multi-exposure functionality allows creative layering of images.
Interchangeable Viewfinders and Screens:
- The M645 is a true system camera. You can swap out viewfinders and screens to tailor your shooting experience.
- Available viewfinders include waist-level finders, prism finders with built-in light meters, and magnifying finders for critical focusing.
- The bright focusing screens aid precise composition.
Lens System:
- Mamiya offered a range of high-quality lenses for the M645, including wide-angle, standard, and telephoto options.
- The lenses feature helical focusing, which allows smooth adjustments without extending the lens barrel.
- Popular lenses include the 80mm f/2.8 (a versatile standard lens) and the 150mm f/3.5 (great for portraits).
Flash and Accessories:
- Dedicated flash sync terminals allow external flash units to sync at 1/60 second.
- The M645 supports various accessories, such as motor drives, cable releases, and lens hoods.
- While it lacks the modularity of some other systems, it covers the essentials for serious photography.
Legacy and Influence:
- The Mamiya M645 paved the way for subsequent models like the M645 Super, Pro, Pro TL, and 645E.
- Its reliability, image quality, and ease of use endeared it to photographers worldwide.
- Even today, vintage M645s find their way into the hands of film enthusiasts who appreciate the medium-format experience.
In summary, the Mamiya M645 is a classic workhorse—a bridge between compact 35mm cameras and larger 6×7 systems. Whether you're shooting landscapes, portraits, or street scenes, the M645 delivers medium-format magic.
