Well, I'm searching for a hiking style backpack / camera bag that will hold all my gear (150-500mm / 17-50mm / camera, etc) AND my tripod. I'm not too worried about fast access. But a small amount of room to grow would be nice. My collection won't grow fast, but it WILL grow . Bonus if it can be considered a carry-on bag at airports. Barring that, I'm looking for a method of transporting a tripod without having to hold it, or have it constantly swinging into your side for hours on end. One that's compatible with backpacks. Any ideas or suggestions?
