I've been shooting concerts occasionally for a school paper for the last few years (see http://www.physics.ubc.ca/~gmarsden/gallery for a few older examples). I've generally been fairly happy with them, but have found I have a real problem with focus. In particular, I have a lot a sharp microphones with fuzzy faces in behind. I use HP5 at 1600, two older EOS cameras (Elan and 10S), 50/1.8, 85/1.8, and 20/2.8. I find that I can't see well enough through the view finder to focus manually, or even adjust the autofocus. Clearly a larger f-stop would help, but I find I mostly need f/2 - 2.8 to get enough light onto the film at hand-help shutter speeds. Any suggestions on what I can do to improved my focus? Maybe I should practice more with adjusting the autofocus? Or should I spend my time developing a steadier hand so that I can shoot at lower shutter speeds and get a larger dof? Thanks.
