HD PENTAX-DA16-50mmF2.8ED PLM AW - ZoomlensA new-generation Star-series lens, assuring high-contrast, high-resolution imaging even at image edges, and delivering clear, crisp images with minimal aberrations
This large-aperture standard zoom lens is the latest model of the new-generation Star (★) series, which is designed to provide the best possible image quality and accommodate the super-high-performance cameras of the future. Its newly designed optics assures greatly improved contrast and sharpness compared to previous models, while compensating various aberrations to a minimum and delivering sharp, clear images not only in the middle of the image field but at 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 effectively minimizes chromatic aberration over the entire zoom range.
HD PENTAX-DA★ 16-50mm F2.8ED PLM AW
A large-aperture standard zoom lens for use with K-mount APS-C-format digital SLR cameras, featuring the cutting-edge design of the new-generation Star series
This standard zoom lens has been developed as the latest model of the new-generation Star (★) series, designed to provide improved image quality and high-speed, high-precision autofocus operation to accommodate the super-high-performance digital cameras of the future.
By incorporating the latest optical design technologies, the optics has been completely redesigned to assure high-resolution, high-contrast images even at open aperture. Compared with the existing smc PENTAX-DA★ 16-50mm F2.8ED AL[IF]SDM launched in July of 2007, this lens delivers greatly improved imaging performance.
It also incorporates a PLM (Pulse Motor) for the first time in a large-aperture lens to assure high-speed, low-noise autofocus operation. It is even fine-tuned for greater operability in manual-focus operation.
This new zoom lens allows users to fully enjoy the process of photography according to their own preferences.
Standard lens for APS-C sensor cameras
This new standard zoom lens for cameras usung APS-C sensor, like PENTAX K-3 Mark III, compensates various aberrations to a minimum and delivers sharp, clear images, not only in the middle of the image field but at the edges.
Incorporating one ED (Extra-low Dispersion) glass optical element, one anomalous glass optical element and two ED (Extra-low Dispersion) aspherical glass optical elements, it effectively reduces chromatic aberration to a minimum over the entire zoom range.
Coupled with high-grade, multi-layer HD Coating*, which reduces the average reflectance in the visible ray spectrum to less than 50% that of conventional multi-layer coatings, it effectively minimizes flare and ghost images even in demanding lighting conditions such as backlighting.
This standard zoom lens delivers exceptionally high resolving power and outstanding contrast even at open aperture, while capturing beautiful images with a smooth transition of the bokeh (defocus) effect and a true-to-life depth of field.
Since its maximum aperture is fixed at F2.8 over the entire focal-length range from 16 to 50 millimeters (equivalent to 24.5mm to 76.5mm in 35mm format), this large-aperture zoom lens makes it an ideal regular-use lens for the PENTAX K-3 Mark III.
* HD stands for High Definition.
High-speed AF system
This zoom lens incorporates a newly designed optical system which features a lighter, more compact focus-lens group. By driving this focus-lens group with an advanced PLM (Pulse Motor), it assures smooth, high-speed autofocus operation with minimized operational noise.
Thanks to the redesigned focus mechanism, it provides the minimum focusing distance of just 0.3 meters, and the maximum magnification of 0.24 times, making this a handy, regular-use lens for capturing all types of subjects — from everyday snapshots to close-ups and landscapes.
Electromagnetic diaphragm mechanism
This zoom lens features an electromagnetic diaphragm control mechanism* to assure high-precision exposure control when used in combination with compatible digital SLR cameras.
It also lets the user capture video clips using automatic exposure control, even when there are considerable differences in brightness during the video shooting.
When mounted on a PENTAX K-3 Mark III, PENTAX KP or PENTAX K-70 camera body, the PLM (Pulse Motor) assures smooth focus tracking operation and flawless exposure control, while considerably reducing annoying noise generated by focus and diaphragm control operations during video shooting.
Its assures smooth, worry-free video shooting in locations prone to considerable brightness changes — such as a stage with rapidly changing lighting conditions, or a forest with filtering sunrays — or with active, fast-moving subjects such as athletes or animals.
* The lens features the KAF4 mount, and is compatible with electromagnetic diaphragm control. Electromagnetic diaphragm control is available in combination with PENTAX K-3 Mark III, PENTAX K-3 II, PENTAX K-3, PENTAX KP, PENTAX K-70, PENTAX K-50, PENTAX K-S2, PENTAX K-S1, PENTAX K-1 Mark II** or PENTAX K-1 ** camera bodies.
**When mounted on a PENTAX K-1 Mark II or PENTAX K-1 camera body, images can be captured only in Crop mode, because the camera’s image circle is exclusively designed for the APS-C format.
Dustproof, weather-resistant construction
Developed as an AW (All Weather) model, this zoom lens features a dustproof, weather-resistant construction to prevent the intrusion of water and dust particles into the lens interior. By pairing it with a PENTAX dustproof, weather-resistant digital SLR camera body, the user can create a highly durable, reliable digital imaging system that performs superbly even in the most demanding shooting conditions — in rain or mist, or at locations prone to splashing water.
- Nine-blade circular diaphragm to produce a natural, beautiful bokeh (defocus) effect (from open aperture to F5.6 in the wide-angle range; from open aperture to F8 in the telephoto range), while minimizing the streaking of point light sources
- 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
- SP (Super Protect) 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.
