I do not cease to rejoice at the purchase, a very good deal!

As some pentaxists wrote - for birding (photo hunting) you want more, it is treated by buying a converter - relatives are a little expensive, Tamron, Kenko are our salvation. Now I understand that the 1,4x converter is the most for it - it will be 420mm and the picture is still more interesting (despite the drop in aperture ratio) than the Tokina 400mm f5.6 fix is ​​allowed.
If you can find at least 40-50 Definitely recommend - you won't regret it!
The question of the budget as they say)
Regarding the crop factor on this lens, the DA series is designed for APS-C (crop) cameras, but on the Pentax K-1 crop lenses are corrected for full-frame.

Pros

1) Good aperture for such a focal length, 2) Excellent color reproduction and contrast, 3) Gorgeous bokeh for a telephoto lens, 4) Good resistance to light and backlight, 5) Quality of assembly and materials used, 6) Dust-, moisture protection, 7) Quick-Shift Focus mechanism, which gives good efficiency when shooting, 8) Silent motor. 9) Weight, like Jupiter-21m 200mm f4 :)

Cons

1) PRICE! (salvation - secondary market, rarely but it happens), 2) The lens hood is a bit too big (but of course the manufacturer knows better), 3) Autofocus is not fast enough, especially noticeable when shooting dynamic scenes.
