SPEED, SHARPNESS, PERFORMANCE, VERSATILITY Built to meet the rigorous demands of professional photographers, the HD PENTAX-D FA 24-70mm F2.8 ED SDM WR is sure to become your go to lens! It’s designed to deliver speed, sharpness and performance, while producing a beautiful soft bokeh (defocus) effect on the background throughout the entire focal range. Providing a constant aperture of F2.8 over the entire zoom range, this fast versatile zoom lens greatly reduces the need for a tripod when photographing subjects in less-than-ideal lighting conditions. By incorporating three ED (Extra-low Dispersion) optical elements and four aspherical optical elements, it assures sufficient light levels even at the edges of the image field and compensates various aberrations to a minimum to deliver well-depicted, fine-detailed images, rich in contrast and resolution. The built-in SDM (Supersonic Direct-drive Motor) provides quiet, high-speed autofocus operation.

Exceptional image quality

Consisting of 17 elements in 12 groups, the newly designed optics feature three ED (Extra-low Dispersion) optical elements, one anomalous-dispersion-glass aspherical optical element and three aspherical optical elements to accommodate super-high-resolution image sensors.

Large-aperture zoom lens

The HD PENTAX-D FA 24-70mm F2.8 ED SDM WR covers a versatile focal length range from 24mm to 70mm on a 35mm format sensor and 37mm to 107mm when mounted on the current PENTAX K-series APS-C camera bodies. The large F2.8 constant aperture makes this lens ideal for wide variety photographic opportunities such as wedding, portraiture, sports, nature, landscape, studio, field and low-light photography.

Weather-resistant construction

This lens features a dependable weather-resistant construction with special seals to effectively prevent the intrusion of water into the lens interior. By pairing it with a weather-resistant PENTAX Digital SLR camera body, it assures a durable, dependable digital imaging system that performs superbly in demanding shooting settings — even in rain or mist, or in locations prone to water splashing or spray.

HD Coating to optimize image rendition

The lens is treated with high-grade, multi-layer HD Coating. Compared with conventional multi-layer coatings, this PENTAX-original coating assures higher light transmittance and less reflection to deliver bright, high-contrast images free of flare and ghost images, even under demanding lighting conditions such as backlight.
