Like all Pentax lenses, this lens is treated with smc coating for maximum light transmission, sharp definition, and high contrast images. In addition, SP (Super Protective) coating made of a special fluoride compound has been applied to the front surface of the lens through the use of a unique evaporation process. As a result, the lens offers excellent water- and oil-repellent performance and makes for easier cleaning should the lens be accidentally smeared with fingerprints or cosmetics.
Note! Not compatible with "full-frame" (35mm size) cameras
Key Features Designed for Digital SLRs The image circle in DA-series lenses is designed to perfectly match the 23.5mm x 15.7mm size of the CCD used in Pentax digital SLRs to optimize camera performance. This design also contributes to a drastic reduction in size, weight and production cost, compared to 35mm-format counterparts with similar specifications. DA*-Series DA*-series lenses feature tightly sealed, weather-resistant and dust-resistant construction that enhance durability for use in rain or dusty conditions. SP Coating SP (Super Protective) coating made of a special fluoride compound has been applied to the front surface of the lens to offer excellent water- and oil-repellent performance. Quick-Shift Focus Quick-Shift Focus System allows to instantly switch the focus mode from AF to manual with a slight twist of the focus ring. High Optical Quality Incorporates Extra-low Dispersion (ED) glass lens elements to compensate for chromatic aberration.
