Does anyone use this lens for sports? I'm a budget photographer (until I can afford an L) and I tried using the 55-250 to shoot some pickup lacrosse today. at 1/1000 on Tv mode the aperture wasn't large enough (could only get to f/5) even though there was not a cloud in the sky (though I was shooting in pesky mid day light). I tried shooting on auto ISO which helped a little but I lost a lot of color and detail. When I amped up the exposure of the 100 ISO shots in ACR afterwards I got a lot of noise at 100% (the shots below might look fine b/c they aren't at 100%). 1/800 and below didn't freeze the action so I felt like I was stuck in a corner here... Are there any work around's for using this lens with sports for 100% sharpness?
Here are some of the best ones I took:
