Take a look at my Facebook fan page.
I used the MkII for a cabaret last night, all at ISO 6400 and 1/50 sec at 2.8
Fortunately they weren't moving too fast but the only other lens I had was the 135L which was calling me, whimpering even from behind the DJ box, I would of got it but it would of only taken me to 1/100 and Id still get a bit of shake so saw no point.
If they were moving faster I would of.
I put all the images on Facebook through Noiseware btw, so lost a little sharpness in the process.
