Bumping this thread because I'm interested in what everyone is using for Camera Bags.
I love the ThinkTank stuff, but I know there are some other big innovators in this category. Right now I use a ThinkTank Digital Holster 20 V2.0 for hiking... I use their attaching harness on my BlackDiamond backpack, even though it's designed for their own backpacks, you can make them work on nearly anything if you get creative. I would like to find a backpack that's better suited for the abuses of hiking in rocky terrain, but can also pack the necessities of survival as well.
As it is now, if I want to bring any other lenses hiking, besides my 17-55, I just stuff them in among my packed clothing layers that I'm not wearing.
And of course... here's my contribution to the Pr0n thread.
