The camera delivers impressive image quality with improvements in noise performance, as well as an extended ISO range. Video quality has been improved, and not only does the camera offer additional colour settings for photography (including a new clarity setting), the D810 also offers advanced video colour settings for those that want to get the highest quality and dynamic range from video. With a tried and tested body design inherited from the D800/E, the camera delivers high image quality at an improved shooting speed.

When it comes to image quality, the Nikon D810 is surely a beast.

We have received a few reports from some users of the Nikon D810 digital SLR camera indicating that noise (bright spots) are sometimes noticeable in long exposures, and in some images captured at an Image area setting of 1.2× (30×20).

After looking into the matter, we have determined that some noise (bright spots) may on occasion be noticeable when shooting long exposures, and in images captured at an Image area setting of 1.2× (30×20).

Video from the D810 remains among the best you’ll get from a DSLR, and all the options that made the D800 so popular in this area remain intact. Nikon added a stereo microphone to make nicer scratch tracks for your moving pictures or for those situations where you don’t feel the need to use an external audio recording device.

I have a D800e, the sensor and IQ of stills on the D810 are pretty much the same. The normal dynamic range and shadow recovery of still images is extraordinary. For studio photographers who do not need to shoot 11 frames per second or have extra aggressive weatherproofing designed to withstand being in a war zone or hurricane, there is no other full frame that will deliver better pictures. The 810 has the superior autofocus of the D4s. It also has a much quieter shutter than the D800 which was a big complaint. Nikon is playing catch up on the video front and the D4s, D750 and D810 are large leaps forward for still shooters who need pro quality video. The D800 was used for the TV series "Wilfred" along with being the B camera in later seasons of "Dexter." Obviously some pros like what Nikon is bringing to the table with this series of cameras.

It is silly to make a blanket statement that Nikon is making crap cameras that none wants. Not true. Their main focus has been towards pro still shooters. The D4s far outperforms Canon, Sony, Panasonic and Olympus for both low light capture and low light autofocus. It is a pity that they do not beef up their video features to that of Canon or Panny so we would have better video features in the King of Low light performance.

I was still shooting on a GH2 that I hacked for better video. I am the first person to insist that M43 cameras can take pro-quality stills and are not amateur toys. I am so blown away by the IQ of the D800 series that I now gladly lug around a much larger and heavier kit when still shooting to get the dynamic range, shadow recovery and detail of my Nikon.

The moire issue for stills is over exaggerated. Probably why Nikon felt confident enough to do away with the anti alias filter altogether in the D810. With such fine resolution I have not seen moire in stills. With the lower resolution of video I can see why that may be more of a problem. Also though I did not expect the same high ISO performance as the D4s, these high megapixel cameras do really well at higher ISOs. Noise might pop in sooner but by the nature of the 36 megapixel sensor the noise has a very fine grain and has a pleasing quality not dissimilar to the gran of fast analogue film. The fine grain noise in a raw photo is easily tamed in Lightroom.

Also Nikon glass rocks. Nothing beats my 14-24 f/2.8 Zoom, the 85 1.4 which has clinical sharpness with the creamiest bokeh and the 200mm f4 micro a legendary macro lens. The available glass had much to do with my personal decision to buy Nikon.

If you mostly need video functions and only do some still, the D810 might not be your best choice. If you need a small lightweight kit M43 is probably the way to go. For people who do studio still, gallery sized prints, landscape or other areas where this camera is an industry leader. Nikon knows who is buying their cameras and really focusing on their needs and priorities. Canon models in equivalent classes seem to be better generalists for a broader market which makes them a perfect product for other consumers.
