When attempting to replace a bayonet mount on my AF-P 70-300mm Nikkor lens, I inadvertently lost one of the 8 signal pins (CPU contact).Is there any source where I can just get a signal pin (or a set if I have to)?

Any help would be greatly appreciated.

Your only hope is someone selling salvaged used parts (or salvaging them from another lens yourself). Other than a few external cosmetic parts, such as rubber grips and battery doors, Nikon does not sell parts to anyone - even camera repair shops with great reputations. At least not in the U.S. and Canada.

  • \$\begingroup\$ @PeterM Thanks for the link. I was under the impression the deadline had already passed for third party repair shops that were once Nikon authorized repair centers. \$\endgroup\$
