Description

Pentax 24-70mm F2.8 ED SDM WR HD Lens

A high-performance, interchangeable standard zoom lens for use with PENTAX K-mount digital SLR cameras, providing exceptional imaging power and a large F2.8 maximum aperture

When mounted on a 35mm-format full-frame digital SLR camera body (currently under development), 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.

  • Exceptional Imaging Power

    Exceptional imaging power

    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. By assuring sufficient light levels even at the edges of the image field and compensating various aberrations to a minimum, it provides a high MTF (Modulation Transfer Function) and delivers well-illustrated, fine-detailed images that are rich in contrast and resolution across the entire image field. When mounted on a current PENTAX K-series camera body, it uses only the central area of the image circle so that it delivers high-resolution images with uniform image description over the entire image field.

  • Water Resistant Construction

    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.

  • Built-in SDM (Supersonic Direct-drive Motor)

    Thanks to the incorporation of a new-generation SDM (Supersonic Direct-drive Motor), this zoom lens assures quiet, high-speed autofocus operation, allowing the photographer to react swiftly to all types of subjects.

  • 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. *2:HD stands for High Definition.

  • 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.
