>>3722172inside is an xt10 mirrorless with a pentax 35-70 w/ adapter, a tascam pcm recorder with space above it for an extra lens (which would also secure the camera laterally) that i don't own yet. pockets for books or laptops, extra batteries, rolls of film, and some uhh... botanical inspiration. one of the pockets is currently empty but big enough for a 35mm film body if you need to carry both, which would push the weight a bit but still doable. overall i find a sling is more immediately accessible than a backpack which is crucial for unexpected scenes. not to mention it looks a little more "grown-up" if you care about that sort of thing.
