(commentary)
Ordered 7/11/2014, shipped 4/14/2015.
What product took so long to appear? A US$50 Nikon TR-N100 tripod mount for the 70-300mm CX lens. During that entire time, this part was out of stock at pretty much every US dealer I talked to.
Nikon has a long history of producing accessories slowly and not keeping them in stock. Makes you wonder why they’re even in that business. If accessories are such a headache to keep stocked correctly, license that stuff out to a third party who knows how to get it right, simple as that.
Moral of the story: order the minute an accessory becomes available if you want it. Don’t dally.
