Description
- The smc PENTAX DA Star 55mm F1.4 SDM is a prime standard lens that is ideal for portrait, still-life, or low light photography.
- Adding the PENTAX Aero Bright coating on internal lens elements offers ultra high refraction index for improved light transmission with minimal ghosting and flaring.

- Its fast F1.4 aperture offers outstanding depth of field control, and its rounded diaphragm blades create a more circular aperture for smooth, beautiful bokeh at large aperture settings.
