Thanks Paul, I'm looking forward to experimenting with the 20-35, it seems a good supplement to the 24-105 and its a group A lens on the 5D3 It will probably need extension for close shots.
Thanks David and Goldscout, I've been using G series for backpacking for years and the G1X IQ is so good I don't feel I'm sacrificing if it grabs the image instead of the 5D. On our Greek trip last year they really complemented one another. From Goldscout's great gallery it looks like I'll be using the 70-200 quite a bit for street and the G1X can provide the backup wide range.
Thanks Rockant, I've thought about a vest. My light field jacket has large cargo pockets which I'll press into service if necessary. Always good to have contingency plans.
