I suffer from backaches and cannot currently carry heavy materials. My camera weighs slightly more than 1kg, though. I have no problem carrying it on my shoulder, but it's not something I enjoy doing for obvious reasons (theft, damage, etc).
I am currently looking for a camera bag that doesn't hurt my back and doesn't call much attention. I am also thinking of buying a non-camera bag and adapting it with an insert.
Any suggestions? I've seen a ton of casual-looking bags that interest me, but I'm not sure if they are proper for my back. I had my eyes set on a vntage canvas casual camera bag, but I'm not sure it's what I'll need. Still, I'd appreciate some advice, since I understand nothing about this subject.
