I've decided I need a new camera bag. Although I've never been one to complain, carring around my body, 2 lenses and tripod in a messenger bag is killing me. By the end of the day my neck and back are all cramped up and sore, and I feel more worn out than after a hockey game... It's pathetic. So I need something different. I was considering a backpack, like the Burton Zoom, but have heard it's not convienent if you are constantly removing your equipment from the bag, which I am. I've seen the modular belt systems, but am not sure if i'm comfortable enough with my sexuality to handle that.... Ideas? Recommendations? I know there was someone on here with the Burton.. How is it? Ease of use? Comfort? thanks!
