For the last few years, I've used a Luma Labs sling setup with my L-bracket equipped 6D. However, this fall I'm getting a 70-200/2.8, and will need to support it by the tripod lug.
What have you guys found to be an efficient system for quickly swapping a sling between a body and a lens tripod mount? I don't need it to be an Arca plate, as I already have one for the body (and will be buying a plate for the lens). Op-Tech? Peak?
