Originally posted by tuco I've have tried several "camera backpacks". The latest one was a Lowepro Trekker AW. I'm an avid hiker and none I've tried so far work well. They seemed designed more for protection than hiking. The Trekker I had seemed made for a very large person. It was good for hauling gear from your car a short distance. But it had no provisions for water bottles on the side, food and clothing.
I just use a regular - comfortable - hiker's day pack and stow the gear in it. I use an extra long neck strap on the camera so I can carry the camera at my side like a bag instead of in front on my chest.
Probably what I'll do... 90% of my photography is done while I'm out hiking and backpacking, because that's what I do with 90% of my free time. I've decided to break down and get a Pelican case to use while canyoneering and climbing, but have not found a good solution for backpacking/hiking yet.
Deuter does make dedicated side pockets that lash to both my daypack and hiking backpack... I might sew or cannabalize another camera bag for some padding to add into those for lenses. My other thought is to take apart the hip belt and thread in a couple lens cases, and use a hip pouch for film, filters, etc, but that would leave everything out in the rain. There are large packs designed for backpacking with LF gear, but they're really cost prohibitive... One of these days I'll put together a good solution.
