Best for
A classic fast standard prime for Pentax K-mount. At 50mm on full-frame (K-1/K-1 II) it's the definition of a 'normal' lens - natural perspective, great subject isolation at f/1.4. On APS-C bodies it becomes a 75mm equivalent - ideal for portraits. Beloved for its rendering and bokeh character.
