I am considering getting this lens and was wondering if anyone is using it to shoot indoor sports. If so, are you pleases with the results and will it focus fast enough for Basketball. I have read a lot of post comparing the Tamron to the Canon and Sigma and at this time can not justify the Canon but am looking to get either the Tamron or Sigma in the next day or so. My main reason for getting this lens is not just sports but some other needs but if I could use it for indoor sports that would be great.
Thanks
