A new-generation, high-performance Star-series lens delivering superb imaging power and exceptional resolving power
This large-aperture, single-focus standard lens is the newest model in the acclaimed PENTAX Star (★) series — the lineup boasting the best imaging performance of all PENTAX lenses for use with K-mount digital SLR cameras. The lens delivers the superb imaging power demanded of a new-generation, high-performance Star-series lens, assuring exceptional resolving power from the center to the edges of the image field, even when set to open aperture.
Thanks to PENTAX-original lens coating technologies — including the latest Aero Bright Coating II assuring exceptionally low reflectance, and the high-grade HD Coating — it produces extra-sharp, high-contrast images free of flare and ghost images. Its dustproof, weather-resistant body also makes it extremely dependable and durable for shooting in demanding outdoor conditions.
- New-generation, high-performance Star-series lens with large F1.4 maximum aperture
- This lens has been developed as a new-generation member of the high-performance Star series — a lineup designed to deliver extra-clear, high-contrast images with edge-to-edge sharpness by compensating various aberrations to a minimum. After conducting an extensive review of the Star-series standards, PENTAX has designed this lens to assure greatly improved resolving power, looking ahead to its use with more advanced, next-generation camera bodies. It provides exceptionally high imaging performance even at open aperture, in addition to a beautiful bokeh (defocus) effect and an outstanding image rendition at close ranges. Developed as the first model of the new-generation Star-series lenses, this large-aperture: standard lens boasts an extra-large F1.4 maximum aperture, useful with many different subjects in a range of applications, including portraiture with an effectively defocused background, and handheld shooting of indoor scenes.
- State-of-the-art optical technology
- 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 — this lens effectively reduces flare and ghost images to a minimum even in demanding lighting conditions such as backlighting. By incorporating three super-low dispersion glass elements and one aspherical element in its optics, it effectively compensates chromatic and spherical aberrations, and produces brilliant, high-contrast images with edge-to-edge sharpness. Since it minimizes distortion even at a focusing distance of approximately one meter, it produces crisp, distortion-free images over the entire focusing range, from the minimum focusing distance to infinity.
- Dustproof, weather-resistant construction
- Developed as an AW (All Weather) model, this 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 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.
- Newly developed ring-type ultrasonic wave motor SDM
- This lens features a newly developed ring-type SDM (Supersonic Direct-drive Motor), which generates as much as 7.5 times the torque of the conventional SDM installed in existing lenses. Thanks to this enormous driving power, the lens assures a smooth, high-speed shift of the heavy, multi-element rear lens group during focusing operation.
- Others
- 1. Nine-blade, round-shaped diaphragm to produce a natural, beautiful bokeh (defocus) effect up to F2.8 aperture: setting, while minimizing the streaking effect of point light sources
2. A minimum focusing distance of 40 centimeters, effective in capturing images with a defocus effect
3. Electromagnetic diaphragm-control mechanism,* for flawless, high-precision exposure control during movie recording
4. SP (Super Protect) coating to keep the front surface free of dust and spots
* This mechanism is available when the lens is mounted on a K-1 Mark II, K-1, K-3 II, KP, K-70, K-3, K-S2 or K-S1, K-50 camera body.
USAGE NOTE:
This lens features a KAF4 lens mount compatible with an electromagnetic diaphragm control system. Cameras compatible with this system are K-1 Mark II, K-1, K-3 II, KP, K-70, K-3, K-S2, K-S1 and K-50. For K-1, K-3 II, K-3, K-S2, K-S1 and K-50, the camera’s firmware must be upgraded to the latest version.
If this lens is mounted on a camera without proper firmware upgrade, its diaphragm control mechanism becomes inactive, making it impossible to obtain correct exposure.
