Nikon D810 Key facts
It has the same 36.3-megapixel resolution as the D800’s sensor, but it’s an all-new device. Coupled with the EXPEED 4 image processor, it enables a standard sensitivity range of ISO64-12800, and ISO32-51200 in expanded mode. The optical low-pass filter has been removed.
The D810’s upmarket Multi-CAM 3500 autofocus module is an improvement on the D610 and Df. It boosts the total number of AF points to 51, with 15 crosstype points. Better still, it’s the revamped edition of the module, as fitted to the D4s, so boasts faster autofocus performance.
It’s a high-resolution camera, so the maximum burst rate isn’t exactly quick. Even so, it hits five frames per second thanks to the increased readout speed from the new sensor, and the faster throughput of its EXPEED 4 processor.
Unchanged from the D800 is the 3D Colour Matrix III 91000-pixel metering module. It’s also the same as that used in the D4s, and employs a higher resolution than the 2016-pixel module used in the D610 and Df. A bonus over the D800 is the new ‘highlight-weighted’ metering mode.
Tough and rugged, the D810’s entire body shell is made from magnesium alloy, and built to take the knocks of a professional working life. Weather seals guard against the ingress of damaging dust and moisture, to the same level as those featured in the D610 and Df bodies.

The high megapixel count results in sizeable image files. A single 14-bit RAW file can be as large as 75MB, while a TIFF file can be nearly 110MB. The latter will see you filling an 8GB memory card with as few as 71 shots. You can shoot in ‘small RAW’ mode, with a reduced pixel count.
