I bought this to use on my Sony A7, and it was great. However I found that my photography is now more relaxed than it used to be. As much walking and looking as taking pictures and having the camera hanging from my hand wasn't always what i wanted. I bought the rope neck strap version, and everything is perfect now. I can have the camera more safely hanging on my chest, (inside a jacket if the weather is not so good), which i find more comfortable. If I want my camera 'more to hand' I have a trick i guess most people know of making a double loop in the neck strap and putting my through the loops... it then becomes a wrist strap. Both options in one strap... I am happy, thanks PD. So pick you preference and buy accordingly, or buy both like me and try them out, both are recommended. P.S. the wrist strap has been passed to a friend, who is also happy.
