This bag accommodates my H4D body and lenses better than any other bag I've tried. The depth and rectangular shape do the trick. The materials, two handles, and carry-on dimensions are its best features. This is a bag that opens best when it is placed on the ground; access is very good. However, when it is hung from a tripod hook (as I often do when on wet sand, snow, or very wet ground, it is much more difficult to open and access items in the lower recesses of the bag because the zipper has to be opened along the bottom. Three hands/arms are an advantage in this situation.
