Hello, I am soon to be jetting off to a few large cities around the world and have some trouble selecting gear. I have a 5D Mark III, 5Dc, 500D and a wealth of film cameras. Lenses I'd consider taking include: EF 17-40mm f4L Zeiss Distagon T 24 2.8 EF 35mm f1.4L EF 50mm f1.4 EF 85mm f1.8 I was thinking, based on what lenses I find the most enjoyable to shoot with, 17-40/35/85. But then I am concerned whether this will not cover all desired focal lengths for walkabout (not interested in telephoto for this trip). Should I include the 50? It is small and lightweight. If I do, should I ditch the 35, considering 35 falls into the 17-40 range? My concern with the latter is that I will lose a fast wide. I am not to keen taking the 24, as I usually only use it for precision shots (architecture, design references, etc.), and don't want to risk the glass (despite it being built like a tank). What do you guys think?
