HD PENTAX-D FA★70-200mmF2.8ED DC AW

  • 35mm Full Frame
  • APS-C
  • Zoom
  • D FA★

Thanks to its large-aperture design, it provides a large maximum aperture of F2.8 at all focal lengths from 70mm to 200mm

Coupled with other PENTAX-original lens-coating technologies — such as the newly developed 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, even under demanding lighting conditions such as in backlight. In addition to four Anomalous Dispersion Glass elements and two ED (Extra-low Dispersion) Glass elements, its optics includes a pair of new Super ED glass elements to effectively compensate chromatic aberration over the entire zoom range and deliver crisp, high-resolution images with edge-to-edge sharpness.

Features / Specifications

High-performance Star (★)-series lens with large F2.8 maximum aperture
This telephoto zoom lens has been developed as a new model of the high-performance Star (★) series, which assures exceptional image rendition with edge-to-edge sharpness by effectively compensating various aberrations to a minimum. It provides a zoom ratio of approximately 2.9 times to cover a telephoto range from 107mm to 307mm in the 35mm format. Since it provides a large maximum aperture of F2.8 over the entire zoom range, it is ideal for portraiture with beautifully defocused foreground/background and sports photography demanding high shutter speeds to freeze the action.
State-of-the-art optical technology
This zoom lens is treated with the newly developed Aero Bright Coating II — a lens-coating nanotechnology that employs a super-low refractive film fabrication process to assure light reflectance lower than that of the conventional Aero Bright Coating.*
* A state-of-the-art, PENTAX-original lens coating technology developed from nanotechnology. It applies a silica aerogel coating layer with uniform porous structure over a regular multi-coating layer to reduce surface reflections across a wide wavelength range and produce crisp, high-quality images.
Dustproof, weather-resistant construction
Developed as an AW (All Weather) model, this zoom lens features a dependable dustproof, weather-resistant construction with 13 special seals to prevent the intrusion of water and dust particles into the lens interior.
Newly installed three-position switch for Quick-Shift Focus System
In order to improve its operability, a three-position switch is newly installed on this lens, allowing instant switching among QFS/A, QFS/M and MF modes. QFS/A is an autofocus-priority mode, which allows the user to switch to manual-focusing operation only when autofocus operation is completed. QFS/M is a manual-focus-priority mode, which enables the user to switch to manual focusing at any time — even when the AF system is in operation. MF mode allows the user to instantly switch to manual focusing with a simple twist of the focus ring on the lens. With a choice of three distinctive modes, the user is assured of speedier, more accurate focusing operation for a given subject or application.
Other features
・Smooth, quiet AF operation using a lens-installed AF driving motor
・Round-shaped diaphragm to produce a natural, beautiful bokeh (defocus) effect, while minimizing the streaking effect of point light sources
・Focus range limiter to minimize AF operation time by fixing the focus range to one of three sub-ranges
・SP (Super Protect) coating to keep the front surface free of dust and stains
・Detachable tripod mounting with a newly designed anti-falling mechanism

Since it is impossible to avoid light diffraction phenomenon on the actual lens, wave optical MTF is more realistic.
However, geometric MTF is appropriate if you want to compare only the effects of geometric aberration correction on MTF.
