I'm pretty partial to Crumpler gear bags. I've been using the 7 Million Dollar home for a few years and I love it. The velcro dividers inside are awesome for when you wanna switch up your setup. I carry a Nikon DSLR, Nikkormat FT2, Diana, 28mm, 50mm, 135mm, 18-105mm, 28-80mm, 70-200mm, 300mm and a few C mount lenses, a bipod, and other miscellaneous gear normally and it all fits.
