I'm going to be going on a 4 night trip to New York in a few weeks and will primarily be in the manhattan area. I won't have a car and will be going around sightseeing on foot so I'd like to avoid carrying TOO MUCH weight. I also don't want to be changing lenses all the time since I'll be traveling with my gf and really don't want to stop every 10 minutes to swap lenses. I know the easiest would probably be to pack the 18-200VR with 35mm f2 for lowlight, but there's a part of me that really wants to bring my 24-70 since it's a relatively new purchase for me and I would really like the opportunity to use it. If i take the 24-70 and leave the 18-200 at home, will I miss the 70-200 range? Do I need the 10-20mm for some fun UWA shots? What about flash? Do museums in NY allow the use of flash? Any advice would be great. My kit is as described in my sig below. What would you bring if you were me?
