It appears you can just never have enough camera backpacks and bags. I have two different sized backpacks, but there are times when I want something smaller and more portable. I think I'm looking for either a shoulder bag or perhaps something that goes around my waist. Here's the problem I'm trying to solve. When I'm outdoors, I often walk/hike holding my D2X usually with the 17-55 attached. There are many of these occasions where I'd like to bring with me a few of my other lenses (70-200VR w/TC 1.4, 105 macro VR or Sigma 10-20). In these circumstances, I really don't need anything else with me other than just two additional lenses and I'm fine with hand carrying the camera itself with one lens attached. In this case, my camera backpacks are a complete overkill and I may already have to be carrying another backpack with water bottles and snacks in it (imagine a family hike). So ... I'm looking for some kind of bag that could either hang from a strap over my shoulder or around my waist that could hold two of the above lenses. Any suggestions? For reference, I already have two LowePro camera backpacks of different sizes (both of which are too large for this type of job).
