FWIW, I received the bag yesterday (Think Tank Retrospective 30). The bag is well built/sturdy canvas-type feel, is loaded with pockets/dividers, and has very nice zippering with nice adjustable straps/carry handles. Looks like a man-bag and not a camera bag. Only 2 'complaints' are that when carrying over the shoulder, the cover flap is pretty long and must be folded over itself to gain full access to interior, but because it is so big, it does serve well as a shelf when changing lenses - very handy even though it slows the lens-change process down slightly. The other minor flaw is the side pockets are 2 small/tight to carry gatorade bottles- they barely fit a slim water bottle. But, there is a handle loop where you can hang a carabiner to a lexan bottle, so no biggie but just one more thing flopping around, and one more item to remember to bring. Better for the environment I guess, (and my gut,) as now I'll bring Crystal Light, instead of buying gatorade
