My review is simple.
I will never shoot another wedding without it again. Period. My upper back and neck thank me so much for using this. There are some minor cons but without question for me, the pros completely outweigh them.
Pros:
-Excellent distribution of weight across your shoulders
-Very easy access to two different bodies
-Cost, far cheaper that some alternatives
-Holds snug to your chest and feels very secure
Cons:
-You have to use OP/Tech's neck strap when you convert back to a single camera setup
-When shooting a shot above your head, you can not reach as high as your arm will reach, only takes about 10 seconds to disconnect but for some shots the opportunity is gone.
-When squatting down, the lens on the body not being used can touch the ground. I got around this by just putting the camera in my lap as I squat down. When I stand up it moves to my side with no issues
Here a few pictures from a wedding I shot in June that my cousin took of me with the dual strap in action. Here are a few pics from the actual wedding itself.
