Jim, Just before the end of the year, I was moving from one shooting location to another. I didn't tighten the knob well enough on the tripod clamp and my D4 and 200-400 VR both crashed to the ground. It might have well been concrete with the frozen road. The two broke apart with significant damage to the mounts on both.
I packaged them up and sent them by Fed-Ex so they'd have them on January 2nd. With NPS, they looked them over and billed my credit card for around $1150, but both have been on Parts Hold since.
After seeing the Parts Hold for quite a few days, I went ahead and purchased a new D800 to use with my 70-200 VR2.
Just curious, after the repairs, did both units work back to pre-drop condition?
