@Ultrafrozen : yes you can crop a bit more without exposing the details (or lack thereof ..) As far as I know Sigma's lenses tend to give slightly softer results, and that seems to be the case for me as well, but I'n no pro by any means
The other big plus was being able to get more pics in a row before the buffer was filled (6 as opposed to 3 with the Pentax), even if the fps is almsot the same (2.7 vs 3)
Thanks for all your comments but there are a lot of people taking these kinds of pics here so it's not that usual to get pics published, though I have had some pics in one magazine, covering some of the veteran events we have over here.
Can you guys recommend any US magazines, esp if they have websites, would be interesting to see what's happening over there, esp in terms of racing, and also what kind of pics they like. I have heard from one photog on another forum that many mags don't like panning shots b/c they feel the blurry bg will give people a headache ...
