Originally posted by jeffshaddix Good catch on the 150, I was thinking 250 from earlier musings.
The 250 is needlessly powerful on a 55-300, it vignettes horribly and has too close subject distance.

As I don't care much about video, the screw-driven AF has never been an issue to me. It is not slower than SDM (nor DC, unless proven) and unlikely to break.
Not slower to focus when it finds focus, no. But the 55-300 hunts more frequently than any lens I've ever owned. And the whine is bird-alarmingly loud.

If so, I will definitely have one. Hopefully it has rounded blades too. The 18-135mm bokeh is amazing for a consumer zoom.
Originally posted by derekkite I wonder how they are managing to make the zoom weather resistant?
Pentax has several weather-resistant zooms; 18-55, 16-50, 18-135, 50-200, 55-135, 60-250.
