Ok so after many years I have decided to embrace my inner geek. I am headed to the Star Trek convention in London this October and need some help deciding what lens to use. I bought the VIP ticket so I'll have front row seating in the main hall. I'll be in a full Star Fleet uniform so I don't see myself caring around allot of gear. So my question to you is with a 5D MkII what one lens do you think would be most useful to carry, I realize one lens can't cover the vast lightning changes or the all the different distances but work with me here???? Cost really is not an issue.
I'll be the first to admit I am a beginner with expensive gear but I'm working on getting better.
Thanx for any input/thoughts/opinions, have a good one.
