I'm going to a private dance/concert where some of my friends in a jazz combo will be playing. I'll probably be able to get quite close to the band. At most I want to bring two lenses. It will be quite dark in the venue. I have a GH2. Here are my "fast lens" choices, in order of max aperture: Panasonic 25mm f/1.4 Panasonic 20mm f/1.7 Olympus 45mm f/1.8 Panasonic 12-35mm f/2.8 I'll want some close-ups as well as some full ensemble shots (if possible). Which two would you bring?
