Many times as a tourist I like a camera (sometimes two) hanging off sling straps, and often want access to another couple of lenses, cell phone, wallet, etc. What I don't want is to be schlepping around a larger bag along with two bodies on sling straps - too bulky and too much to juggle. I've decided that the answer is a hip-bag just large enough to hold two or three lenses, or possibly two lenses and a Pen body, cell phone, wallet. The two that I'm considering are: Domke F-5XB $79 Interior: 9.5 x 6 x 4 Think Tank Hubba Hiney $49 Interior: 10.5 x 6.5 x 4 Any thoughts comparing these two bags for hip-use would be great. Thanks.
