  4. Product Overview

A large-aperture standard zoom lens assuring high-contrast, high-resolution imaging, even at image edges, and with minimal aberrations

HD PENTAX-DA16-50mmF2.8ED PLM AW

A new-generation Star-series lens, perfected
in pursuit of the ultimate in image quality

HD PENTAX-DA16-50mmF2.8ED PLM AW

The newly designed optics assures great improvement in contrast and resolving power, while compensating various aberrations to a minimum and delivering sharp, clear images across the image field.

Exceptional resolving power assured by uncompromising optical design

Superb resolving power and delivers super-clear, high-contrast images from the middle of the image field to the edges. By incorporating one ED (Extra-low Dispersion) glass optical element, one anomalous dispersion glass optical element and two ED (Extra-low Dispersion) aspherical glass optical elements, it reduces chromatic aberration to a minimum over the entire zoom range.


HD Coating

A coating with a high level of hardness and durability, reducing reflectance to less than 50% of conventional multi-layer coating, delivering multi-layer coating for a new age, which is highly effective in suppressing ghost images and flares. The advanced lens construction is also effective in suppressing flares for superb imaging that reproduces subjects with clarity and contrast.

Despite its large open aperture of F2.8, the HD PENTAX-DA16-50mmF2.8ED PLM AW (left)
assures high resolution even at the edges of the image field.



Minimized chromatic aberration (at 45mm F2.8)

Even at the open aperture of F2.8, this lens effectively minimizes various aberrations.

Improved bokeh effect thanks to an increased maximum magnification (at 50mm F2.8)

Because the maximum magnification has been increased to 0.24 times from the previous model’s 0.21 times,
this lens produces the bokeh effect over a broader area, while softening the effect in overlapping areas.



Superb anti-backlight performance (at 16mm F8)

Thanks to PENTAX-original HD (High Definition) Coating, this lens minimizes the generation of ghost images,
even against harsh backlight.



High-performance PLM for quiet, high-speed autofocus operation

The focus-lens elements are directly driven by a PLM (Pulse Motor), providing much-improved focusing speed (approx. 2.2 times faster in the wide-angle range, or approx. 1.5 times faster in the telephoto range, compared to the smc PENTAX-DA16-50mm F2.8ED AL[IF] SDM),* while effectively minimizing noise for quieter operation. Manual-focus operation of the power-assisted focus mechanism has also been upgraded to optimize the precision and response of detecting the focus ring. As the result, the focus-lens elements shift more efficiently and flawlessly in synchronization with focus-ring operation.

* When using AF.S mode for viewfinder shooting of still images, at a distance of 0.3 meters to infinity.

By dividing the optical element group into two, the weight of the focus element group is reduced to 1/3 making it possible to use PLM motor.

Dustproof, weather-resistant AW (All Weather) construction

This lens features All Weather (AW) construction to prevent the intrusion of dust and water into the lens interior. Pair it with a PENTAX dustproof, weather resistant digital SLR camera body for creative shooting in rain or mist, or other locations prone to splashing water.

Super Protect (SP) Coating

SP coating is a PENTAX-original special coating that provides superior performance in repelling water and oils. It is used on the front surface of the first high-performance lens for effective protection of the lens surface. This coating not only prevents adhesion of dust, water drops, oils, and other substances, but it also makes it easy to wipe off objects that adhere to the lens.

Comparison of dirt adhesion (oil-based ink)

A lens surface treated with SP Coating has a very smooth surface without the adhesion of the oil-based ink.

Comparison of wipe-off (oil-based ink)

A lens surface treated with SP Coating can be wiped clean more easily and completely, even after the ink has dried.

Quick-Shift Focus System

After focusing using the autofocus, the focus ring can be turned to allow immediate focus adjustment using the manual focus. This feature enables smooth operability by eliminating the need for an AF/MF switching operation. This is useful during closeup photography, for instance, when you want to shoot while making fine adjustments to the focus.

the HD PENTAX-DA16-50mmF2.8ED PLM AW
