My wife and I are going to visit our daughter in the UK in April, and the three of us are going to spend some time in Reading (where she lives) and London, and then go over to Amsterdam and Prague for a few days each. I am planning to bring my 7D and nifty 50. I want to save carry on room so I don't plan to bring my camera backpack or other lenses. My daughter will probably bring her Sony a58 and one smaller lens.
Is it relatively safe in those cities (theft-wise) to walk around with the camera around my neck, maybe partially tucked into my overcoat? Any tips or experiences (good or bad) would be appreciated.
