Mamiya / Phase One 645 medium format camera system


  • Mamiya pioneered the 645SLR system camera in 1975
  • The 645 format is the smallest, lightest, and cheapest roll-film design. Negatives are a little squatter than the standard 35mm frame (24x36mm) and therefore full-frame printing on standard paper sizes such as 8×10 need not require a cropping decision.
  • in 2006, Mamiya were selling their photography business to IT company Cosmos
  • in 2009, Phase One bought a controlling interest in Mamiya and also in Leaf, a company which makes digital backs for medium format cameras, and developed a strategic alliance with lens manufacturer, Schneider-Kreuznach.
  • in 2015, Phase One replaced their DF+ camera system and introduced their new heavier XF camera system featuring:
    • Honeybee Autofocus Platform (HAP-1)
