Here's a little issue I am dealing with. Anyone using a camera strap system, knows to keep checking the tightness of the keeper that resides in the tripod socket. The short of the story, I didn't and a D5 with 24-70 hit the gym floor. Camera is fine with no mount problems. The lens is in two pieces with the from element section separated from the rest of the lens.
I called my friend at Roberts and bought a nice used one. I then took photos of the injured lens and sent them to https://www.peachtreecamerarepair.com/ in Atlanta.I sent info 3 times and heard nothing back. I live in Nashville, 3 hours way.
I finally sent the lens to http://www.nikoncamerarepair.com/ in the Chicago area. I had heard that they used to be a Nikon repair station, but they do more than that now. It's a 24-70 2.8 and I will sell it somewhere upon return.
Those Black Rapid connectors are TIGHT now and forever more.
