have you looked at the owners reviews and in depth review yet ?

The HD PENTAX-D FA* 70-200mm F2.8 ED DC AW telephoto zoom lens was announced at the CP+ tradeshow in February, 2015 preceding the announcement of the K-1 Pentax 24x36mm full-frame DSLR. Together with the HD Pentax 150-450mm extreme telephoto zoom lens these are the first Pentax lenses to cover the 24x36 mm 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. With a respectable maximum aperture of F2.8 and rounded diaphragm blades for smooth Bokeh this zoom can be used as a portrait lens in addition to its more traditional use for sports, wild life and distant landscapes.

This lens is pro-grade as indicated by its star designation and also by its feature list:
* All-weather protection (AW)
* HD coating
* SP coating of the front element
* Aerobright II nano-coating of the inner elements
* Four super-low dispersion elements, two ED elements and two super ED elements with properties like flourite elements
* 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.

In August of 2020 a limited quantity siler version was announced.

HD Pentax-D FA* 70-200mm F2.8 ED DC AW
In order to cater to professional photographers, a manufacturer must meet several requirements. In addition to a full frame body, a 70-200mm F2.8 telephoto lens is very high on the list. It is thus not very surprising that Pentax released its own version of that lens just prior to the launch of the Pentax K-1 itself.

I usually leave switches in their default position. Unless I know the AF distance and really need faster focusing, then I move the focus limiter, but 99% of the time I don't need to do that, because AF is fast enough.

Indeed I would suggest reading the in-depth review.

Long story short : green labels are the default position.
