- 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.
- 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.
- Adding the PENTAX Aero Bright coating on internal lens elements offers ultra high refraction index for improved light transmission with minimal ghosting and flaring
- The tightly sealed, weather-resistant and dust-resistant construction enhances durability for use in both rainy and dusty conditions, making the DA Star 55mm F1.4 SDM lens a perfect companion for the weather-resistant PENTAX DSLR bodies.
- The PENTAX-original Quick-Shift Focus System allows instant switching from autofocus to manual focus operation.
Boasting such features as super-low-dispersion optical elements, extra-low-dispersion (ED) optical elements, and Pentax original lens coatings, the Pentax DA* 55mm f/1.4 lens delivers crisp high-contrast images even at the edges. The lens is outfitted with a water- and dust-resistant seal for reliable operation in inclement conditions, along with a Pentax Quick-Shift Focus system that allows you to instantly switch between auto and manual focus. The objective lens surface, meanwhile, is treated with Pentax original (Super Protect) SP coating, a special fluorine compound that's applied through a vapor-deposition process to create a surface that effectively repels dust, water, and grease. The combination of special lens coatings, ideal curvature, and superior positioning of optical elements optimizes a host of digital imaging characteristics while effectively minimizing flare and ghosting. Other features include an Aero Bright coating for maximum light transmission, rounded diaphragm blades that create a more circular aperture, a fast f/1.4 aperture for outstanding depth-of-field control, and a 1.48-foot minimum focusing distance. An ideal lens for portraits, still life, or low-light photography, this Pentax 55mm lens carries a one-year warranty.
