50mm · f/1.7
The Minolta MD Rokkor-X 50mm f/1.7 is a budget-friendly vintage lens offering good center sharpness when stopped down to f/2.8 or f/4, but wide open at f/1.7 it is soft and exhibits coma (Lumenicity). Build quality is mixed: some versions have plastic focus and aperture rings (Lumenicity), while others are mostly metal. Bokeh is circular at f/1.7 but becomes hexagonal due to six non-rounded blades. It suits photographers seeking an affordable, lightweight manual lens for portraits or street photography, especially on mirrorless cameras with an adapter.
