It was painful for me to have to carry my Sony Alpha 77 II with its original strap. As soon as I leaned, he was hitting everything he was around me. Especially since I added grip and it's heavy. I looked at the pros and saw that several had Black Rapid straps. I hastened to look at this on Amazon. And I do not regret my purchase. It's really great practice and you can walk for hours with. I still have some difficulties to adjust well because despite everything, the NPC rotates around its axis during walking and tend not remain sticking to me, that's why I did not put 5 stars. Or it must keep hold of it, not always practical. Delivery by Amazon still as nickel. I recommend this product.
