With the Nikon D3, D3S, D4 and D4S, when I lay a single-point AF sensor over a subject's eye, I get the eye in focus for a huge percentage of the shots. However, the camera had trouble locking on to the key part of a subject's face when face detection was not on. The 51-point phase-detection focus system can be set to single-point focus 9-, 21- or 51-point dynamic focus group area or 3D tracking. The D810 had no problem tracking moving subjects and locking on, and the wealth of autofocus options gives the photographer the chance to tackle any scene. In fact, it's on a par with the D4S - which isn't surprising, considering the D810 uses the same AF system. The Nikon D810's autofocus is much faster and more accurate than the D800's.

The detail on the fly making a landing to the left of the bloom is astounding, the legs are clearly visible and the proboscis tongue can be seen extending toward the flower. The level of detail the D810 captures is breathtaking, as is evident in this quick handheld shot of flowers at a park, and in a cropped section from that shot. The extra f-stop of lowered light sensitivity really makes the camera more usable in bright sun (without the need for a light-restricting neutral density filter). As part of the redesign of the camera's internals, the D810 now can shoot down to ISO 64. In bright conditions, it would be hard to find a DSLR that produces better images than the D810. Our lab also shot photos of test patterns with the very sharp 58mm lens and used the imatest evaluation software to judge factors such as color accuracy and noise at different ISOs. ![]() Samples in this review are original JPEGs, and I confirmed that they are faithful to how images appear in RAW. I tested the D810 by capturing images in both 14-bit uncompressed RAW files and JPEG at the highest resolution to compare the results. Even the venerable 24-70mm, a mainstay of so many photographers, had a slight softness to its images when compared to the supersharp 58mm or even the 50mm. The D810 demands good glass because the sensor reveals so much detail that it magnifies the strengths or weaknesses of a lens. I tested the Nikon D810 with a number of Nikkor lenses, including the 35mm f/1.8, the 35mm f/1.4G, the 24-70 f/2.8G zoom and the 58mm f/1.4G. To that end, I evaluated many of the test images for this review at 100 percent size in order to see what's going on at a pixel level. ![]() That means that noise is a concern with cameras like the D800 and D810, especially in low light. ![]() The D810 promises to eliminate this pattern without requiring the filter, thus resulting in sharper images.Īs megapixel count increases on a sensor, the amount of noise (graininess) tends to increase as well, since the individual pixels on the sensor need to get smaller and closer together. It's meant to remove moiré - a pattern of wavy lines that appears in photos of fine lines or shapes that are too high-detail for the sensor. ![]() The D810 is one of the few DSLRs to come without an OLPF. Nikon claims the new sensor in the D810 further boosts image quality, though it's not clear if Nikon has done anything new, aside from removing the optical low pass filter (OLPF). I spent a lot of time shooting with the D800, and its images are among some of the most incredible I've seen from any DSLR I've tested. ![]()
