The smc PENTAX-DA* 200mm F2.8 ED[IF] SDM is a uni-focal telephoto lens with a focal length equivalent to 307mm in the 35mm format. With a maximum aperture of F2.8, it is ideal for indoor sports events and stage performances requiring fast shutter speeds to freeze action, and for portraits against a smooth, beautiful out-of-focus background. Featuring advanced technologies such as special optical glass elements and PENTAX-original lens coatings, it is designed to assure exceptional optical performance and deliver clear, high-contrast images, even at image-field edges. It also features ED (extra-low dispersion) optical elements in its second and fifth lens.
SDM mechanism, assuring extra-smooth, super-quiet autofocus operation using a supersonic motor installed in the lens (Conventional autofocus operation using a camera-installed motor is also possible.)
Dust-resistant, weather-resistant construction with a set of seals to prevent intrusion of dust and water into the lens
Inner Focus mechanism for effective compensation of various aberrations at all focusing distances
SP (Super Protect) coating applied to the front surface of the optics to block dust and dirt
Quick-Shift Focus system for instant switching to manual-focus operation after the subject is captured in focus by the AF system
