Hello all, I have had my 60D now for 6 months and I love it. My wife and I are going to Disneyland with our daughter and I'm hoping to get some really nice photos. I will be mostly shooting in manual and AV,and I was looking for any advice on ISO. I still have trouble at times adjusting the right light setting. I'm going to take my 18-200mm and 28-105mm lenses. I'm also thinking of taking the nifty-fifty. Any suggestions would be greatly appreciated.
