50mm · f/1.7
The Minolta MD 50mm f/1.7 is an affordable, compact manual-focus lens with mostly metal construction but a plastic aperture ring. Optically, it offers good center sharpness stopped down to f/5.6–f/8 (Lumenicity), but wide open at f/1.7 it is soft and exhibits coma (Lumenicity). Bokeh is circular at f/1.7 but becomes hexagonal due to six non-rounded blades. It suits budget-conscious photographers seeking a lightweight normal lens for portraits or street photography, especially when stopped down (Freddy T. Robles).
