The HD Pentax-D FA* 70–200mm f/2.8 ED DC AW lens is a professional telephoto zoom lens for the Pentax K-mount.
Announced jointly with the HD PENTAX-D FA 150-450mm F4.5-5.6ED DC AW in February 2015,[1] it is one a pair of full-frame lenses to reboot Pentax' involvement in that format, the last previously introduced full-frame lens being the D FA 100mm weather-sealed macro lens in 2009.
On Pentax APS-C cameras, the D FA* 70–200mm has an equivalent focal length range of 107–307mm.
It is the first Pentax lens to feature Super ED glass for improved chromatic aberration suppression and Aero Bright II nano-coating to minimize flare.
The D FA* 70–200mm lens is also one of the first two Pentax lenses to feature an improved implementation of the Quick-Shift Focus System (full-time manual focus), with QFS/A and QFS/M positions on the autofocus switch.
