Many of the Domkes can handle the F3/MD4 with no problem. Domke F2 can fit 2 bodies/motors with 4-5 lenses, flash and a lot of film; the F6 is a bit smaller - maybe 1 F3/MD4 plus FE or FM body and 3-4 smaller lenses. They don't have much padding except on the bottom, but the canvas is heavy and they tend to mold to the shape of your hip over time. I've never cared for the metal clasps on the flap, but they are very secure when latched and make it difficult for someone to easily reach into your bag on a crowded sidewalk.
