Originally posted by FengyBoy I think the AF is fast enough, I can't notice it's any slower than 50-135mm. There's no "noticeable wobble" when it's extended. But I'm not sure if it can cope with your holding fashion, since I've never tried that.
Thanks for the input. Do you have the 50-135? (Didn't see it listed in your sig) It just feels really slow when compared to my DA*300 which is quick and snappy. It's a toss up between the DA*60-250, DA*200, or Sigma 70-200 (although I really want to stay with the Pentax lenses).
