Hi, new here, from The Netherlands. Question: I will be visiting New York with my family. Lots of walking the streets and sight seeing from rooftops. Should I stick with my Zeiss 35/2.8 and Sony 28/2.0 (on my A7R2)? Small and practical, and sufficient, I think. Or, should I add the 55/1.8, or perhaps even the new 70-300mm? I think I will buy at least one of those once anyway, but not now already if not necessary. Thanks for your thoughts.
