I have the Domke J803 which is the ballistic version, used to have the canvas one but not both at once so I can't compare. I think they're the same design and size but not sure. The J803 is a surprising bag! I have a narrow 3-compartment Domke insert in the main compartment, and recently put in TWO Canon 5D bodies, Nikkor 20mm f/4 w/EOS adapter, 35mm f/2 and 85mm f/1.8 EF lenses, AND a 420EX and a Vivitar 2800 flashes. Plus then there were the 2 front pockets with compact charger, 2 spare BP511A batteries, a few CF cards, lens cleaning cloth, small blower bulb, and a couple other items I don't recall. The bag was definitely pregnant looking but the clasp reached the ring (barely).
