We were on the flooor, probably about 15 rows from the "T" (30 rows from the main part of the stage.
I have an XT and switched back and forth between a Canon 85mm 1.8 and Sigma 18-125 3.5/5.6. The pics I posted are cropped in for closeup of Miley. I was able to get the Canon shots at ISO 400, but bumped the Sigma shots at 125mm to ISO 800.
I was pretty pleased with them.
Without embarrasing myself - pretty good concert too.
