Service advisory



On August 19, 2014, Nikon acknowledged a problem reported by some users, of bright spots appearing in long-exposure photographs as well as "in some images captured at an Image area setting of 1.2x (30x20)." Existing owners of D810 cameras were asked to visit a website to determine whether their camera could be affected, on the basis of serial numbers. Repairs would be made by Nikon free of charge. If bright spots still appear in images after servicing, Nikon recommends enabling Long exposure NR. Products already serviced have a black dot inside the tripod socket.

Nikon D810A



An astrophotography variant with a special infrared filter capable of deep red / near infrared and with special software tweaks like long exposure modes up to 15 minutes, virtual horizon indicator and a special Astro Noise Reduction software was announced February 10, 2015. The D810A's IR filter is optimized for H-alpha (Hα) red tones, resulting in four times greater sensitivity to the 656 nm wavelength than the D810. In comparison, Canon's astrophotography DSLR's 20Da and 60Da Hα sensitivity was 2.5 times and 3 times (respectively) more than the standard 20D / 60D. The D810A additionally has 1.39 stops advantage due to the larger image sensor format â€" resulting in better than 2 stops sensitivity advantage giving over four times faster exposure times compared to the Canon 20Da/60Da.

Although the D810A can be used for normal photography, due to the deep red / near infrared sensitivity the white balance may fail in case of fluorescent light or difficult cases with very strong infrared light â€" requiring an external infrared filter.
