I have been working out of a Kinesis belt system for several years. It works very well in the field, but not so well as hiking gear. It is also harder to pack up when you want to hit a restaurant. I am thinking about the Photobackpacker system - I already have their modified pack, so I would add their lens cases and a camera case. For folks with this system, how do you use it in the field, i.e., for changing lenses. I often work in places where I would prefer to not set anything on the ground. How easy is it to get things in and out while holding the bag in your hands?
