I have need for a new camera bag. I've got a 17" laptop, which complicates things a bit. I have a Canon R7, a couple of lenses, various laptop pieces, etc. I want a backpack, or a bag I would be able to carry on to an airplane, should I ever choose to fly again. I mostly travel by car, but I would like something that is compact enough I could carry it when needed. Thoughts? Thank you! Mike.
