Nikon have announced that users of the Z8 Mirrorless Camera may in rare instances experience difficulty with a lens that cannot be mounted on the camera because the lens cannot be rotated to the locked position.
Additionally, Nikon acknowledges that the metal camera strap eyelets in the camera may become loose or separate from the camera body. It has become clear that this issue may occur if a Z 8 camera strap eyelet is subjected to conditions such as a strong impact or continuous heavy stress.
*A free of charge repair for both the above issues are now available via H Lehmann for your Nikon Z8 - carriage fee will be applied if required.
