I have the 5B which is a great camera bag.It will hold both of my Contax G2's, and my 4 lenses,but that is a tight fit. I usually have one camera on my shoulder and the other inside.I really like the flap and zipper. In most cases when shooting , I leave the zipper open and just lift the velcro flap with my free hand to get a lens or film. When It needs to be secured in a crowd , I zip the inside zipper. This makes a very water proof bag that I have used in downpours without getting cameras wet. I also use canvas waterproofing spray (kiwi ) on all my domke bags, up to 5 coats. I put it on before I ever use the bag. I had this bag sitting in 4 in of water in the bottom of a dingy and the cameras never got wet. I also use the Domke mailman pad on all my camera bags, I keeps the strap from slipping off even if you bend over to pick something up off the ground. It also distributes the weight better when I carrry a bag all day.
