The HD PENTAX-D FA 150-450mm F4.5-5.6 ED DC AW telephoto zoom lens was announced at the CP+ tradeshow in February, 2015 in connection with the announcement of a Pentax 24x36mm full-frame DSLR to be introduced late in 2015. Together with the HD Pentax-D FA* 70-200mm F2.8 zoom lens these are the first Pentax lenses to cover the 24x36mm full-frame format since the D FA 100mm F2.8 WR lens, which was introduced back in 2009.
While this lens is designed for the 24x36mm full-frame format it can also be used on cameras with the APS-C sensor format. This lens has four autofocus buttons on the lens barrel. These buttons together with the enhanced Quick-shift system provide for a lens that is fast in use and pegs it as a lens designed for sports and wild life. These AF buttons can be used with the K-3 (after a firmware update) and newer cameras. The lens sports rounded diaphragm blades for smooth Bokeh.
It is a variable aperture zoom which helps keep weight and size down.
The key features of this lens are:
* All-weather protection (AW)
* HD coating
* SP coating of the front element
* One super-low dispersion element and three ED elements
* AF buttons on lens barrel
* Enhanced Quick-shift function via a three-way switch on the barrel
* Focus limiter
* Tripod mount
The lens hood has the for Pentax traditional removable piece that allows for easy adjustment of an attached polarizing filter.
The lens has a built-in DC type autofocus motor and no provision for screw drive autofocus. Autofocus is thus not possible with the K100D/K110D and *istD series cameras. Autofocus is not available with film cameras.
