XZ-1 does a school dance show
My daughter does dance classes and during the holiday her performing arts group spent a week rehearsing a few song and dance routines from 'Wicked' and 'Wizard of Oz' to do a little show on the Friday afternoon. Turning up at an event like that with a DSLR and bag of lenses struck me as excessive so I just took the XZ-1. Light in the school hall wasm't too bad; I used ISO 400, Av mode, lens wide open, and got shutter speeds of typically 1/50 sec. I had to time the shots for when the dancers were relatively static but I was impressed with how they cane out; all shot in RAW and NR done with Topaz DeNoise before finishing off with Photoshop Elements.
I reckon the XZ1 at ISO400 produced pictures of comparable quality, in terms of noise and detail, to my DSLR (Pentax K7) at ISO1600 - i.e. plenty good enough for the intended use.
