Last summer, Nikon issued a service advisory for the D750 as a result of a shutter malfunction that it said only some units manufactured between October and November 2014. Now, Nikon is updating that service advisory for cameras manufactured through June 2015, which was just before it issued the original service advisory.
In the updated service advisory, Nikon apologizes for the problem and provides instructions and a tool to check your serial number to see if it is an affected camera. If so, you can send your D750 into Nikon for free inspection and repair to correct the issue even if the warranty has expired.
Nikon has been raked over the coals for problems with its professional DSLRs that end up requiring repair or replacement. Obviously, this does not help Nikon’s image and the company really needs to come out of the gate strong with the new D500 and D5 with no weird malfunctions.
Note: This is likely a gray market item and may not qualify for US warranty service. ebay seller PhotoVideo4Less has a positive feedback rating of 99.9% at the time of this post.
