I use this here shoulder strap/sling. It's awesome because it doesn't screw into the tripod mount so you can keep the mounting plate on the camera if you're doing a lot of tripod shots on the move as i do, it has fast release clips, and it's super comfy. I use an s-biner to fix the camera to my belt loop when i'm hiking or urbexxing (breaking into houses) so the camera doesn't swing around. I think it would fit the bill nicely
