I purchase this bag after try a few other for my rebel xt . the problem be , I like to carry my small video camera with I and could not find a bag to hold both without it feel very cramped with concern that the camera would bang together . in this bag I be able to carry my rebel xt with 28-135mm lens attach , my Canon video camera where the second camera body would go , a 24mm lens , 60mm macro lens , 85mm lens and 70-300mm do lens . I also have room for battery , image card , battery charger , wallet , cell phone and other misc in the pocket . I be afraid this would be really uncomfortable to carry when fill but so far it feel fine . I think I finally find the bag I be look for .
