Hello Friends,
Back-Story
What preceded this condition that follows is that my D810 with a 24-70mm f/2.8 lens mounted on it (while packed away in a padded bicycle saddle bag) slipped off of my bike and hit the ground with a bit of a thud; not violent enough to stop me in my tracks and check my camera's condition. It was not until I attempted to use this camera the following day that I realized I had an issue.
Consequently I am curious if anyone has ever experienced the circular metal lens mounting plate on a D810 (or similar model) essentially "popping away slightly" from the black camera body's housing? When I say "popping away slightly" I mean to say the with a lens mounted on the camera body it appears that the very small gap between the lens base and the camera body exposing a sliver of the mounting plate's metal ring at this location appeared to be slightly askew. What accompanied this "look" was that my lens would not lock-onto the camera body. The lens would fit onto the circular lens mounting plate and fully turn to a stopping point as was customary...but not lock. After attempting to mount multiple lens to this camera body with the same result (lenses would not lock onto the body) I eliminated my lenses as a root cause. What I tried next, with a lens mounted on the camera body, was to apply some inward pressure by carefully pressing the lens barrel (while mounted, but not locked in) into the camera body...I suddenly heard a very subtle "pop" and the askew look of the metal gap between the lens base and the camera body appeared true; meaning a consistent gap-space around the full circumference of the lens base was evident and my lenses would now lock-in.
Soooo, my concerns are;
Did I damage something on the camera body to allow this to happen?
Is the D810's camera body's build such that it is engineered to take a lick such as I described and keep on ticking and I should not be concerned about it?
Should I send the camera body to Nikon for their trouble-shooting in the event something may be broken internally and is likely to result in other down-stream issues?
Any input from the Nikon knowledgebase would be greatly appreciated.
Regards
