Although phone cameras are good enough for most occasions, I still carry my trusty Canon 5d II DSLR with 17-40mm zoom pretty much permanently attached when we go somewhere scenic. The combination is somewhat heavy and bulky. It is too inconvenient to pull it out of the backpack so I carry it in a camera bag cross body style. It makes me look like the proverbial tourist. It is big but provides lots of padded protection. But most importantly the camera is easily accessible and put away for me to take lots of shots.
