Good day group!


A few days ago while being bounced around in a fast moving whale tour boat on choppy water,  I dropped my D5 and 500mm f/5.6 PF lens (attached).

It hit the floor of the boat quite hard.


I took some photos afterwards and they seemed ok on the rear monitor and they look ok at home on the computer.


however,... the bayonet on the D5 is slightly bent, it will not take any other lens other than the 500mm that fell with the camera.


And that 500mm lens?  Yep, the bayonet is visibly damaged, one of the "raised edges" is warped and cracked. It will no longer attach to my other nikon cameras.


Youtube has plenty of DIY bayonet replacement videos.  Simple enough.

I can find a bayonet for the D5 on EBAY, but I am not having luck finding a bayonet for the lens. 


Can someone tell me if any other model lens bayonet can be used on the 500mm f/5.6 PF lens?

I might have better luck finding a replacement if I knew what was compatible.

Even though you say that photos produced with your camera and lens after being damaged are OK, there still might be internal damage to both the camera and lens that could show up later.


Given the value of both your camera and lens, I think I would contact Nikon and see about sending them both in for service. If you are a Nikon NPS member that may help expedite repairs.

I agree with Ron. A lens that has hit hard enough to warp the bayonet needs to go on the optical bench, not only get a new mount. The same goes for the body as the mirror and the AF sub-mirror often go slightly out of alignment when the forces are that severe.
