Originally posted by hcc I suggest that you post photographs with blur. I have a K-3 and DA18-135mm, and I have no problem to shoot actions in outdoor during day time.
First are you sure that it is blur or simply out of focus? This is not the same IMO. Was the focus indicator (green hexagon) on in the view finder at time of shot?
Second was shake reduction SR on when you shot? In the affirmative, did you wait to see the SR confirmation before shooting? The SR confirmation symbol is the 'hand' symbol in the view finder.

I posted photos above, and here are other links to compare
This is the sigma lens on the d200 at the extreme 250mm and widest aperture
This is pentax 135mm at widest, the image has been cropped
I have it on focus priority because I was getting to many blurry shots and I wanted to make sure it was not a focus issue, I hope that is correct way of doing that, but my camera won't shot unless not in focus (hopefully)
No. I don't tend to use shake reduction. I have it off on the lens of the 250 on the sigma. I did shot at a lower shutter speed with the pentax but I was sitting in the same chair both times and I have a pretty steady hand, I would think 1/360 would be sufficient, but maybe not?

Originally posted by FantasticMrFox No, for most sports 135 mm is perfectly fine. In fact, the 55-300's AF is considerably slower than that of the 18-135, making it a worse choice for sports.
Thanks for the suggestion, I posted two links to flicker images above, the pentax definitely looks 'hazy' or blurry to me and I am not sure then what I am doing wrong. I will make sure to use Af-c for action, would that be the cause?
