Hi Pete,

I said hello to you on Friday night. I'm glad to read your comments as it's nice to know it wasn't just me that struggled to get good pictures at the show. I was using 1600/2.8 and, once I realised it was too dark for that, I didn't really know what to do.
I tried using flash but compensated back a long way; however, the vast majority of photos were little more than smudges. I got home and felt I'd failed miserably at an event that had huge potential.
I think the 5DM2 will make life easier judging by the high ISO samples here:
