Pentax HD Pentax-D FA 50mm f/1.4 50mm
A deliberate optical design produces a distinctive rainbow flare effect at f/1.4 against strong backlight, while stopping down to f/4 eliminates all flare for crisp images. Its nostalgic, all-black exterior and full compatibility with vintage K-mount film and digital SLR bodies set it apart from modern lenses. This lens is best for portrait photographers seeking a unique, vintage rendering with an f/1.4 aperture and soft, natural bokeh from its eight-blade diaphragm.
