Yea, i read reviews about the Sigma 70-200 vs canon 70-200. Between the two, the image quality is nearly equal. But the only advantage canon seems to have is faster AF tracking and IS right now.Ray, you should look at the Tamron or Sigma 70-200 F2.8's, or talk Danny into selling you his F4L
yea, it doesn't work shooting ISO 200 in a room that's barely even lit. LOLDamn dude, turn the ISO down, hehe
