The logo (designed by the #Japan Fine Arts School in #Tokyo) represents two #lenses, a #biconcave and a #biconvex set at 90 degrees, with the #Initials S and M. Common folklore wrongly claims it that this represents #Seiichi #Mamiya (in #Japanese his name would be written Mamiya Seiichi). Rather, it represents the two partners of the company #Sugawara #Mamiya
