smc PENTAX DA* 55mm f/1.4

• 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.
• The PENTAX-original SP (Super Protect) coating repels dust, water and grease to keep your lens clean and your image quality at its peak.
• The SDM focus system incorporated in this lens results in a smoother, quieter autofocusing operation using a built-in supersonic motor.
• The focal length is equivalent to 84.5mm in the 35mm format.
• Developed specifically for PENTAX digital SLR cameras.
