Hi all, I'm a forum newbie here.
I'll be heading to Iceland in February to hopefully photograph the Northern Lights. I currently have only the lens that came with my 60D (EF-S 18-200mm f/3.5-5.6 IS Zoom). Do I need to buy a wide angle zoom lens to get the best pictures? If so, which lens would you recommend? Are the Canon lenses better or should I consider another brand?
