I currently have the E-PM2 with the new Panasonic 14-42 II kit lens. I'm planning on bringing that as well as a 7-14 f4 I'm buying for a New York trip... i'm going for 10 days. Should I buy a prime or 2 or another zoom for this trip? I don't want to bring tons of lenses for this trip... I guess I need at least one other bright lens. i could get a 12-35 (bring that to the trip instead of the 14-42) and a prime. Or just the one prime? My budget is about $ 2700.... I am not necessarily looking to spend all of that on lenses though..
