I've been fighting the need for this, but I find it necessary to transition from a traditional shoulder bag to a backpack of some kind that is split somewhat evenly between gear and non-photography items. I see a few options where gear stows in bottom section, and top flap opens to a compartment. That seems fine for me. Hoping I can get some good recommendations on a high value bag. Needs: Comfy strap; capacity to hold body w/lens + 2 more lenses; at least a few extra pockets for accessories; preference to wear it over one shoulder, like the cool kids did when I was in school (and Reagan was president). Don't Needs: Pro-level pack; serious outdoors pack (this will be used in the wilds of suburbia). Any help will be appreciated. I've already watched about 30 minutes of YouTube bag review videos. Hard to tell good from bad, as no one seems critical of anything. Thanks.
