Review from Welling Photography...
I used it all day at a wedding, and it performed flawlessly. On one side, I had a full frame camera with a 70-200, on the other side another full frame, with battery grip, 24-70, and flash on the top. The straps distributed the weight evenly across my upper back, and I never once felt either camera weighing me down like I usually do with a normal rapid strap. My back didn't ache at the end of the night, and I didn't have to worry about the strap sliding around when I raised or lowered each side.
The craftsmanship is really where this strap shines. I had several people, including my second shooter, comment on how clean the lines were, and how it looked like it cost a small fortune. The lobster claws on the bottom held both cameras securely; I never once worried about them coming off. The brass rings slid smoothly along the leather, allowing me to raise and lower the cameras with ease. The S curve on top made the straps conform more naturally to the curve of my shoulders, from front to back.
I love everything about this strap; the craftsmanship is second to none. The quality and care put into these is evident from the moment you try it on, to the last moment before you take it off for the night. Beautiful work.
