@astro_jcm I'm interested to see if you find one! I'm currently using a Lowepro Flipside Trek BP 350 AW, which is a dedicated camera backpack, but it was affordable and it's pretty comfortable. Walked 15km with it yesterday and it did a good job. A single versatile bag would be great though, at the minute I have to have two hiking backpacks, one camera and one regular. That can make planning a trip difficult if I want my camera with me one some walks but not others.
