Mamiya M645 Pro: the modular medium format workhorse that built careers.
The M645 Pro shoots 6x4.5cm frames on 120 or 220 film, giving you negatives that dwarf 35mm without the bulk of a full 6x7 system. The vertical-travel focal plane shutter runs from 8 seconds to 1/1000s plus Bulb, covering everything from long exposures in low light to freezing action in the field. TTL center-weighted metering reads through the lens, and depth-of-field preview lets you confirm exactly what hits the plane of focus before you trip the shutter.
What separates the M645 Pro from simpler medium format bodies is its modular architecture. Film backs swap mid-roll, so you can move between ISO 400 color negative and black-and-white without finishing a roll. Viewfinders and focusing screens are interchangeable, letting you configure the camera around a specific shooting style than working around the body's defaults. The Mamiya 645 lens system built up a deep catalog over decades, and every one of those lenses mounts directly here.
For the price of entry into medium format, few systems offer this much flexibility in a body this well-established. The M645 Pro earned its reputation in studios and on location, and the lenses that pair with it still hold their optical character.
Who It's For
Portrait photographers get the 6x4.5cm negative's smooth tonal gradation across skin, with interchangeable backs letting them switch between color and black-and-white film during a single session. Studio photographers benefit from the modular viewfinder system and depth-of-field preview for precise compositional control under controlled light. Landscape shooters working at slower shutter speeds lean on the 8-second mechanical range and Bulb mode for long exposures at dusk or in low ambient light. Film photographers coming up from 35mm who want meaningfully larger negatives without the weight commitment of a 6x7 system will find the 645 format a practical starting point.

FAQ
- What film formats does the M645 Pro shoot?
- 120 and 220 film in 6x4.5cm frames. A single 120 roll gives you 16 frames; 220 doubles that to 32.
- Can you swap film backs mid-roll?
- Yes. The interchangeable backs let you load different film stocks without finishing the current roll, which is critical for mixed color and black-and-white work.
- How does the metering system work?
- TTL center-weighted metering reads light through the lens, and you can confirm depth of field before shooting with the preview lever.
- What shutter speeds are available?
- 8 seconds to 1/1000s plus Bulb for long exposures. The vertical-travel focal plane shutter handles everything from studio strobes to tungsten-lit interiors.
- Are viewfinders and focusing screens interchangeable?
- Yes. You can swap viewfinders and focusing screens to adapt the camera to your shooting style, whether you need a waist-level finder or a prism viewfinder.
- What lenses mount to the M645 Pro?
- Any lens in the Mamiya 645 mount system. The catalog spans standard primes, zooms, and specialty glass built up over decades.
