What you may not know is that 645 cameras are the smallest of all medium format cameras, shooting a negative about 2.5 times the size of 35mm negatives and allowing for 15 exposures per roll of film. You may already know that analog medium format photography utilizes 120 film, which is physically larger than 35mm and, as such, produces bigger negatives. Read why photographer Chris Buxton chooses to shoot film here, and more of the basics on shooting with 35mm or 120 film here. I’ve taken it on road trips to find that it fits nicely in a backpack, carried it around my neck on long walks through my Chicago neighborhood, and have shot it entirely manual all the while, using the sunny 16 rule as my best friend… Stepping up from shooting digital and 35mm on a Canon A1 that I most often use fully programmed, using this camera had a learning curve in more ways than one. The Mamiya 645 Pro became my first medium format camera a few months ago when I found a great deal on Facebook marketplace that included the 80mm/f2.8 and 150mm/f4 Mamiya/Sekor lenses.
