Sure, that Dryzone 200 and Ultimate Photographers Bag has served you well in your multiple lensman gigs, but you know deep in your heart that the perfect bag is still out there. Maybe the Kata Revolver 8 PL is exactly what you're waiting for.
The winner of a 2012 Red Dot Design Award, it's billed as a "revolutionary backpack for professional photographers." And the "revolutionary" part isn't all hype -- instead, it features a revolver design for the lens compartments, allowing you to reach any of the lenses you have stored from the same access panel by simply rotating the barrel, so you can get exactly what you need without setting the bag down and opening the entire pack.
The Kata Revolver 8 PL can fit a full-sized DSLR with an extra battery grip and a standard lens attached, up to five lenses or accessories, a laptop up to 15 inches, and a tripod on the front straps, along with a bunch of personal gear. Basically, that's everything you'll need for most of your photography gigs, from setup to shooting to post-production. Features include soft-padded harness-straps, an adjustable strap on top, a Spine Guard structure and an insert for hooking it up to a trolley. If you work with a particularly hefty DSLR, you can also attach the camera strap to the mounts on the shoulder straps, transferring the weight to the backpack instead of wearing it around your neck. It also comes with a two-sided weatherproof cover -- one side for wet days and the other for when the sun is out in full force.
