This is the first lens in the designed for both PENTAX film and medium format 645 camera lens. This lens features new optics optimized with 55mm focal length and maximum aperture of f/2.8 for high-quality digital photography to assure exceptional image-description performance, and also provides an image circle covering the image area of existing 645-format film SLR cameras. Flare and ghost images are minimized by Aero-Bright and SP coatings. With seven special seals, the lens’ is made to be Dustproof and Weather sealed (AW) which effectively prevents the intrusion of dust and water to the lens interior. Super Direct-drive Motor (SDM) provides fast yet silent autofocus while Quick-Shift Focus system allows instant switching to manual-focus operation. It is compatible with APS-C and Full Frame Sensor DSLR Cameras.
Product Features in Detail
Incorporating high-performance, hybrid aspherical optical element in its optics, this new standard lens offers exceptional image-resolving power with outstanding brightness levels even at the edges, while compensating various aberrations to a minimum. All lens characteristics are optimized for digital photography: for instance, flare and ghost images are minimized by applying exclusive lens coatings to optical elements and employing anti-reflection materials for the interior of the lens barrel. As the result, this lens can bring out the full potential of the PENTAX 645D/645Z medium-format digital SLR camera.
Versatile standard lens
When mounted on the PENTAX 645D or 645Z camera body, this standard lens offers a focal length of 43.5mm (in the 35mm format), which produces an angle of view close to that of the human eye. As the result, it can be used for many different kinds of subjects and applications, including landscapes and portraits.
Dependable dustproof, weather-resistant construction
Using seven special seals, the lens’ dustproof, weather-resistant construction effectively prevents the intrusion of dust and water to the lens interior. By coupling this lens with the PENTAX 645D or 645Z camera body, the user is assured of a durable, reliable digital SLR camera system that performs superbly in outdoor settings, even in rain or mist or at locations prone to water splashes or spray.
PENTAX plans to use the “AW” (All Weather) designation in the product name of all dustproof, weather-resistant medium-format interchangeable lenses to be marketed in the future.
Aero Bright coating to dramatically improve image description in backlight
The lens is treated with PENTAX-original Aero Bright coating, which delivers brilliant, high-quality images by preventing annoying flare and ghost images more effectively than ever before. Born as the fruit of PENTAX’s advanced nanotechnology, this exclusive coating effectively reduces lens reflectance and greatly increases light transmittance by forming a silica aerogel layer with uniform pores on the surface of optical element.
Rounded diaphragm to produce a beautiful bokeh
This is the first PENTAX medium-format interchangeable lens to features a completely rounded diaphragm. It creates a natural, beautiful “bokeh” (out-of-focus rendition), while minimizing the streaking effect of point light sources.
Smooth, quiet SDM autofocus mechanism
The SDM (Supersonic Direct-drive Motor) autofocus mechanism operates smoothly and quietly using the supersonic motor installed inside the lens barrel.
SP coating to block dust and dirt
The front surface of the lens is treated with PENTAX-original SP (Special Protect) coating, which applies an exclusive fluorine compound to the lens surface through a vapour deposition process. This SP coating not only effectively repels dust, water and grease, but also makes it easy to wipe off fingerprints and cosmetics.
