I'm finally off to NYC this week and am enormously looking forward to giving my new NEX-7 a workout whilst there. I currently have the Zeiss 24mm and the 16-50, and expect to do lots of walkaround shooting with the former, but would like suggestions of what other lens might be useful to me? I'm thinking e-mount lenses for convenience at this stage. The Tokina 116 with my D7000 has given me an enormous love for wide angle lenses and I'm pondering the 10-18 or the Touit 12mm, but already have two wideish lenses and have nothing long. I mostly want to do street photography but would also like to shoot architecture and I suppose other general photography that might benefit from a longer lens; then again I don't have an ultrawide either. I've been considering getting the Samrokibowyangernon 8mm f/2.8 fisheye and the 55-210 OSS zoom from B&H when I get there; however my other option is to put the money towards a 10-18mm or a Touit 12mm (if I feel rich enough on the day). Which sounds the better option? I'm part of a group doing at least two different things on each day, so because it's not like I live there and can go out on a specific camera mission everyday I have that awful n00b urge to take ALL of my lenses just in case I find myself at some wondrous scene that I don't have the right tools for!
