Nikon has announced that the shutter fault in its D750 that it acknowledged in July last year, may be found in cameras from a much wider manufacturing period. Initially it was thought that the issue, in which the shutter occasionally shades part of the image, occurred in cameras produced between October and November 2014. The company has now discovered the same problem in models made from December 2014 to June 2015.

Nikon has promised a free service for all models affected, and an online serial number checker is available for customers to determine whether theirs is one of the models that needs attention.

European customers can check their serial number on the Nikon Europe website, and those in the USA should go to the Nikon USA website. Other region service pages can be found on the Nikon Global website.

Service advisory:

To users of the Nikon D750 digital SLR camera - possible image shading from shutter (update 29/02/2016)

Thank you for choosing Nikon for your photographic needs.

In July of 2015, we announced that the shutter in some Nikon D750 digital SLR cameras manufactured in October and November of 2014 does not function normally, sometimes resulting in shading of a portion of images. Since that time, our examination of the issue has clarified the fact that the same issue may occur with D750 cameras manufactured from December, 2014 through June, 2015.
Therefore, any D750 manufactured from October, 2014 through June, 2015 is eligible for inspection and repair of its shutter.

We sincerely apologize for any inconvenience this issue may have caused.
