Concert photography is all about the faces of the performers, and the emotion that is moment by moment manifested on stage, so I was wondering what the best lense would be to get consistently great CU's. Right now I'm using the standard non-IS 70-300mm telephoto for CU's; and for general concert photos, the 50mm f/1.4 (which I just bought!) as well as the Canon 10-22 (which I just bought as well-can't wait for them to arrive!) So, I'm worried that the quality of CU's will seriously pale in comparison to the MS's and WS's I get . Also, I'm mostly going to be shooting smaller, low-lit venues (like at bars, etc.-I live in a college town). Thanks, any advice is appreciated!
