Pentax HD DFA 50mm F1.4 SDM AW Lens



The PENTAX HD DFA★ 50mm F1.4 SDM AW Lens, part of the company's Star Series of lenses, is a standard length prime lens with a bright maximum aperture that enables accurate low-light shooting as well as providing a wide range of depth of field control. While designed for full-frame Pentax K-mount cameras, the lens can be used on APS-C format cameras where it provides a 76.5mm focal length.


Image rendition at open aperture
Even at open aperture, the lens optimizes the subject’s beauty and elegance with sharply focused eye areas and fresh, lively skin tones. The natural bokeh effect is another distinguishing feature of this lens.


Bokeh effect
Since the lens de-emphasizes the edges of the light source, it creates a natural, true-to-life bokeh effect. It also prevents vignetting from affecting the defocused peripheral areas of the image field, allowing you to emphasize the bokeh effect in the resulting image.


Minimum focusing distance of 40cm
Thanks to a minimum focusing distance of just 40 centimeters, the lens has the versatility for use in a wide range of subjects and scenes, including the photography of flowers and table settings.


Aero Bright Coating II / HD Coating

The lens is treated with PENTAX-developed Aero Bright Coating II — a lens-coating nanotechnology employing a super-low refractive film fabrication process.

By coupling this advanced lens coating with the high-grade, multi-layer HD Coating, which reduces average reflectance in the visible ray spectrum to less than 50% of conventional multi-layer coatings, the lens effectively reduces flare and ghost images to a minimum, even in demanding lighting conditions such as backlighting.









Dustproof, weather-resistant All Weather (AW) construction
Developed as an All Weather (AW) model, the lens features a dependable dustproof, weather-resistant structure with eight special seals to prevent the intrusion of water and dust into the lens interior.

When paired with a PENTAX dustproof, weather-resistant digital SLR camera body, it forms a durable, reliable digital imaging system that performs superbly in demanding shooting settings — even in rain or mist, or at locations prone to water splashes or spray. It also responds to the exacting demands of professional photographers: its focus ring is ideally shaped to assure firm hold and error-free focusing operation even with a wet or gloved hand; it provides dependable operation at a temperature from -10°C to 40°C; and it features the high-rigidity lens barrel structure required for field photography.


New-generation SDM
In order to shift the heavy, rear focus-lens group more smoothly and efficiently during focusing operation, the lens features a newly developed ring-type ultrasonic wave motor SDM, which generates as much as 7.5 times the torque of the compact SDM installed in existing DA★-series lenses. Thanks to this enormous driving power, the lens assures high-speed, high-precision autofocus operation. Because of minimal backlash of the focus ring, it also provides responsive manual-focus operation.


Simple, sturdy yet attractive design
The lens barrel has been designed for a superior appearance. It features a panel line accentuated with the leveled construction of parts, and a uniformly designed body line all the way to the exclusive flower-shaped lens hood. Including the gold line symbolic of the Star-series lens and the familiar deep-green ring — a trademark of PENTAX interchangeable lenses — the lens is in keeping with a design concept standardized for both color scheme and parts positioning. This design concept will be applied to future Star-series lenses, as a reminder of the consistency and dependability of the PENTAX Star series.
