RICOH/PENTAX PENTAX HD D FA 24-70MM F/2,8 ED SDM WR W/CASE

A fast, standard zoom featuring a sophisticated optical design, the HD Pentax-D FA 24-70mm f/2.8ED SDM WR Lens from Pentax is designed for use on full-frame K mount DSLRs, as well as APS-C cameras where it provides a 36-105mm equivalent focal length range. The constant f/2.8 maximum aperture offers consistent performance throughout the zoom range and pairs with a rounded nine-blade diaphragm to produce smooth shallow depth of field imagery. The lens' design incorporates a trio of extra-low dispersion elements, three aspherical elements, and one anomalous dispersion aspherical element to control a variety of aberrations and distortions in order to produce well-corrected images with notable sharpness and even illumination. An HD coating has also been applied to further benefit working in difficult lighting conditions by suppressing lens flare and ghosting for increased contrast and color neutrality.

Complementing the optical performance of the lens is a Supersonic Direct-drive Motor, which offers fast, quiet, and quick autofocus performance that is ideal for both stills and video shooting. A weather-resistant construction is also featured, for working in harsh environments, and a Quick-Shift Focus System and zoom lock lever offer intuitive handling and control.

HD PENTAX D FA 24-70mmF2.8ED SDM WR

Standard zoom lens designed to accommodate the image circle of large 35mm full-frame image sensors.

This large-aperture standard zoom lens covers a focal-length range from 24mm ultra-wide-angle to 70mm standard, and provides a maximum aperture of F2.8 over the entire zoom range. 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.

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 improve image description
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.

Quick-Shift Focus system
The lens comes equipped with the PENTAX-developed Quick-Shift Focus system, which allows the user to instantly switch to manual-focus operation after the subject is captured in focus by the camera's AF system.

Other features

• Rounded diaphragm to produce a smooth, beautiful bokeh (defocus) effect, while minimizing the streaking effect of point light sources.
• Zoom lock lever to prevent the accidental extension of the lens barrel when pointed downwards.
