this is aimed primarily at owners of 5D2/3, which backpack do you use? ive tried to search but cant find the answers i needs so apologies, When I go hill walking for the day I usually take my 5D2 with rs7 strap and either 17-40mm or 24-105mm fitted, till now ive been using a crumpler shoulder bag, but the longer I carry it for the more it bugs me, so anyhow I now want a backpack, not too big but enough to hold the Camera and lens usually with hood reversed, and a few accessories, maybe a monopod and a drinks container, snack bars and wallet/mobile, maybe something similar to the tamrac 5547 adventure 7, so do any of you recommend something along these lines,
any advice greatly received, thanks
