pentax 150-450mm

Seems a new Pentax super telephoto lens is coming. I like the 450mm idea very much, little longer than 400mm, which is also very good. The interesting thing in it that it is noted as a full frame lens.

Obviously this kind of lens is very useful for applications like bird, wildlife, action, sports photography in good light. The interesting question is how sharp the new Pentax 150-450mm at 450mm f/5.6 ?

The lens has a quick focus system, which means it is possible to switch between manual and autofocusing just by turning the focus ring. The lens extends during focusing.

The lens has four dedicated af buttons (every 90 degrees on the barrell), and preset modes are available, but according to our understanding just with the Pentax K-3 camera from recent lineup. The buttons can be used to preset values for focusing or stop continuous focusing at a required point. The lens has a focus limiter as well. The lens is sealed against dust and moisture.

The lens is also got several coatings against dust and finderprints, minimize flare and ghosts. The lens has a zoom lock as well, and circular aperture blades.

The price of the new Pentax 150-450mm lens is 2500 USD. Seems it is not a cheap price, hopefully the lens will be that good. The Tamron 150-600mm runs for 1070 USD, unfortunately not yet for Pentax as fas as I know.
