Bc, Welcome!
I don't think that you can use both systems, I have the Op/Tec sling strap and have connectors on all of my cameras, that way I don't need a strap for each camera, as I can use the same strap for whichever camera I'm carrying at the time. More to your question though, Op/Tec makes a wrist strap that attaches with the came quick connectors that sells for about $7 U.S. I use one when I'm just shooting around the house.
Good advice. OP/TECH is the only carry system I'd use, especially since it's all interconnectable. I like being able to do the quick disconnect and have a bare camera.
