Super-High-Resolution, Medium-Format Digital SLR Photography

Incorporating two high-performance aspherical optical elements in its optics, this ultra-wide-angle lens provides exceptional images with outstanding brightness levels even at the edges while compensating various aberrations to a minimum. Exclusive lens coatings are applied to optical elements, while anti-reflection materials are applied to the interior of the lens barrel. The results help maximize the potential of the PENTAX 645D medium-format digital SLR camera.

Aero Bright Coating Improves Image Description In Backlight

This lens is treated with PENTAX-original Aero Bright Coating to deliver higher quality images.

Dependable Dustproof, Weather-Resistant Construction

As the newest model of the dependable All Weather (AW) series, the lens features a highly dependable dustproof, weather-resistant construction with 11 special seals to effectively prevent the intrusion of dust and water into the lens interior. Used with the PENTAX 645D camera body, the lens offers a durable, reliable digital imaging that performs superbly in demanding outdoor settings including rain, mist, or locations prone to water splashing or spray.

Mountable Circular Polarizing Filter

The lens features a built-in, pull-out-type filter holder in its barrel. By placing the C-PL (circular polarizing) filter (40.5mm in diameter and included as an exclusive accessory) on this holder, the user can easily rotate the filter to obtain the desired polarizing effect.

Smooth, Quiet SDM Autofocus Operation

Featuring an advanced SDM (Supersonic Direct-drive Motor) autofocus mechanism employing a supersonic motor installed inside the lens barrel, the lens assures smooth, quiet autofocus operation.*

* Manual-focus operation only when the lens is mounted on the PENTAX 645N or PENTAX 645N II camera body.
