I scrolled through this thread specifically looking for a mention of Think Tank, glad at least one anon knows what's up. I've got five of their bags and a belt pouch setup, they're hands down the best camera bag company out there and the only one that's actually designed by real working photographers who know what the fuck they're doing.
Oddly my second favorite bag company is Vanquest, a tactical gear company rather than one that even specializes in camera bags, but somehow they understand what works better than any of the big camera bag makers. >>3856675
I own one from around '09 and hate it. Bought it for a travel gig and quickly discovered how horribly designed it was, for some ungodly reason they put the strap mounts way near the back side of the bag so when you put a full load in it it hangs crooked and is super uncomfortable as you walk around, and I have no fucking clue what they were thinking when they decided not to put a back pocket on the thing, I guess they've somehow never been in a situation where they needed to stash paperwork or notebooks or anything in their camera bags.
