And Merry Christmas to you too. I'm not familiar with the cam itself, but in a nutshell, I'd imagine for gigs you would need fast (1.4-2.8f) glass, 35mm, 50mm and 85mm, or 24-70mm 2.8f. Have a look at Canon L series. For Iceland I'd add 24mm 2.8f prime - great for landscape shots, or stick with 24-70mm and add 70-200mm 2.8f for wildlife and things afar.
