I purchased Nikon 200-500 F5.6 lens from B&H in December 2022, warranty card is blank.
Lens is in perfect operating condition, like new, in the box.
Selling for $950 or a best offer. + the actual shipping costs within US.
I also have Sigma EX teleconverters 1.4x and 2.0x available.
Surprisingly, lens is FULLY operational with these - metering / snappy autofocus.
The only limitation, the F-stop displayed in the camera is the F-stop of the lens itself, not adjusted for the X teleconverter.
This is just a display issue, as metering works correctly.
Both teleconverters work really well for Video on Z7/Z8.
For photo - 1.4x sharpness is good at closer distances, 2x same but a bit softer as usual.
