This bag is perfect for smaller cameras. Mirrorless APS-C bodies and point and shoots. You may be able to get away with smaller full frame bodies too but no battery grips and super telephoto lenses. If you have those you're probably not looking at small bags anyway. I can fit my A6400 with 3 lenses (1 attached) and room more maybe another small lens in the main compartment. Main comes with a folding divider that attaches with velcro but there's only a couple differing configurations you could do. The two slim compartments are ideal for cables, cards and extra batteries and chargers. The inner one against yourself is very slim while the outer one is more versatile. Even has a detachable key fob ring for your keys. The non-removable strap has a detaching buckle to take the bag off quick and is attached to two points on each side so that it naturally compresses the bag when you wear it which keeps it from being bulky which I like. The orientation of the strap allows it to be worn over the shoulder or as a belt style fanny pack. The strap is wide nylon but no padding. Adjustments are smooth and easy though. There is also a grab handle that is slightly off balance but not to the point of tilting and risking stuff falling out. This is primarily a camera bag but could function as an EDC, depending on your needs.
