I've seen so many questions posted about photo backpacks that I am reluctant to bother people with another, but I can't find what I am looking for, and I am hoping someone can suggest something.
Backacks are very personal--different people want very different things. Here is my list:
-- It has to have good straps and a comfortable back. I hike up mountains with it. I'm not looking for anything like a sling pack, etc., that many people use in urban settings.
-- It has to hold a 5DIII, a few extra lenses (up to a 70-200), and the usual odds and ends.
-- It has to have a good, central tripod attachment system
-- It should be waterproof or have a removable rain cover. (I can be hours away from a car when the rain starts.)
-- It should have at least one external side pocket for a water bottle.
-- It should have a second, separate compartment for things you don't want mixed up with lenses, like peanut butter sandwiches, bug repellent, and the odd peach. This seems to be the hardest of these criteria to meet.
-- It should have a way to attach a rain jacket or extra shirt on the outside.
-- I don't need a computer pocket and would prefer to be without one if it makes the back less comfortable.
I currently own a no-longer-produced LowePro, a Primus AW, that meets every single one of these criteria except for the second. It was just fine when I carried a 50D, with mostly smaller lenses. It just doesn't quite make it for the larger equipment. Some time ago, a friend who also had switched to FF said to me that he thought my Primus was the best backpack he had ever seen, but he couldn't find anything similar. Then I looked for something similar but a bit larger, and I couldn't find one either. I wrote LowePro, and they steered me to things that seem to lack at least one of these features.
I also have a Tamrac Adventure 9, which I use around town. It is a bit more capacious, and it has all of the features save two: no good way to hold a tripod, and a back that is somewhat uncomfortable for long hikes because of a computer pocket in the back.
Any suggestions?
Thanks.
