During my travels, I have used a lot of different cameras and usually carry 2 cameras. If I am going on a trip where I know I want to get really good photos I will take my Canon DSLR and 4 lenses. I use a Black Rapid strap for my DSLR which holds the camera to the side rather than the front. I also carry a compact camera. Carrying a DSLR all day and lenses can get heavy, so I will decide what is best to use that day and leave the rest in the hotel. If I am going out for the day in a vehicle I will carry everything. If I’m going to be out walking all day I will usually only carry 1 or 2 lenses and a compact camera. For travel photography, I find a wide angle lens is excellent for getting interesting photos. At night if I’m going out I will only carry my compact that fits in my pocket. Here's a photo I took with my wide angle lens.
