The Mamiya M645 is the first series of 4.5×6 SLRs made by Mamiya. The finder and screens are interchangeable, but there is no magazine back, only preloadable film inserts.

All the M645 models share the same accessories (finders, screens, lenses, grips and inserts). The lenses and inserts can also be attached on the later Mamiya 645 models.

The original M645 appeared in 1975. It has knob advance and shutter speeds from 8s to 1/500. It supports a mirror lockup and double exposure lever. Flash sync is 1/60 sec.

"To make things simple, I am going to break this down into three different categories as to why I think this camera is so dang cool. (I’m limiting myself to 3)

1. It’s Multi-frame Option

If you’re anything like me and you HATE frame chop with double exposing 35mm film, then picking up one of these cameras and a roll of medium format film will fix that issue with a click  of a switch...

2. It’s Interchangeable Tops

A big thing that stands out to me about this camera is the level of customization that is available.  For the longest time, I thought there wasn’t such thing as a medium format camera without a waist level view finder...

3. How much it costs to snag one

Medium format photography can get a little pricey if you know what I mean.  Not only does the film cost more per shot but the cameras were made for those professionals out there, which therefore means the cameras were expensive as heck.  Since we now live in the day and age where those professionals of the past are shooting with 5D mark iii’s and D4’s... read more here.  "
