Nikon D3X vs D810
The Nikon D3X and the Nikon D810 are two professional cameras that were officially introduced, respectively, in December 2008 and June 2014. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with a full frame sensor. The D3X has a resolution of 24.4 megapixels, whereas the D810 provides 36.2 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D3X and the Nikon D810? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
An illustration of the physical size and weight of the Nikon D3X and the Nikon D810 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth dimensions are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D810 is notably smaller (29 percent) than the Nikon D3X. Moreover, the D810 is markedly lighter (22 percent) than the D3X. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.
The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Nikon Lens Catalog.
Concerning battery life, the D3X gets 4400 shots out of its EN-EL4a battery, while the D810 can take 1200 images on a single charge of its EN-EL15 power pack. As can be seen in the images above, the D3X has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. In order to provide similar functionality for the D810, Nikon provides the MB-D12 vertical grip as an optional accessory (see here on eBay).

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The D810 was launched at a markedly lower price (by 59 percent) than the D3X, which puts it into a different market segment. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units in a sensor of the same technological generation. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies and lenses.
Both cameras under consideration feature a full frame sensor and have a format factor (sometimes also referred to as "crop factor") of 1.0. Within the spectrum of camera sensors, this places the review cameras among the large-sensor cameras that aim for top notch image quality. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Technology-wise, the D810 uses a more advanced image processing engine (EXPEED 4) than the D3X (EXPEED), with benefits for noise reduction, color accuracy, and processing speed.
While the two cameras under review share the same sensor size, the D810 offers a higher resolution of 36.2 megapixels, compared with 24.4 MP of the D3X. This megapixels advantage translates into a 22 percent gain in linear resolution. On the other hand, these sensor specs imply that the D810 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.88μm versus 5.94μm for the D3X). However, it should be noted that the D810 is much more recent (by 5 years and 6 months) than the D3X, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size. Coming back to sensor resolution, it should be mentioned that the D810 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Nikon D810 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D810 for good quality output (200 dots per inch) amounts to 36.8 x 24.6 inch or 93.5 x 62.4 cm, for very good quality (250 dpi) 29.4 x 19.6 inch or 74.8 x 49.9 cm, and for excellent quality (300 dpi) 24.5 x 16.4 inch or 62.3 x 41.6 cm. The corresponding values for the Nikon D3X are 30.2 x 20.2 inch or 76.8 x 51.2 cm for good quality, 24.2 x 16.1 inch or 61.4 x 41 cm for very good quality, and 20.2 x 13.4 inch or 51.2 x 34.1 cm for excellent quality prints.
The Nikon D3X has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 50-6400. The corresponding ISO settings for the Nikon D810 are ISO 64 to ISO 12800, with the possibility to increase the ISO range to 32-51200.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under consideration, the D810 has a markedly higher DXO score than the D3X (overall score 9 points higher), which will translate into better image quality. The advantage is based on 1 bits higher color depth, 1.1 EV in additional dynamic range, and 0.5 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The D810 indeed provides for movie recording, while the D3X does not. The highest resolution format that the D810 can use is 1080/60p.
Beyond body and sensor, cameras can and do differ across a range of features. The D3X and the D810 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinders of both cameras offer the same field of view (100%), as well as the same magnification (0.70x). The following table reports on some other key feature differences and similarities of the Nikon D3X, the Nikon D810, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The D810 has one, while the D3X does not. While the built-in flash of the D810 is not very powerful, it can at times be useful as a fill-in light.
The Nikon D3X and the Nikon D810 both have an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
The D3X writes its imaging data to Compact Flash cards, while the D810 uses Compact Flash or SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Nikon D3X and Nikon D810 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D810 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the D3X does not offer wifi capability.
Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.
Both the D3X and the D810 have been discontinued, but can regularly be found used on eBay. The D810 was replaced by the Nikon D850, while the D3X does not have a direct successor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon website.
So what is the bottom line? Is there a clear favorite between the Nikon D3X and the Nikon D810? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Nikon D3X:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
- Longer lasting: Can take more shots (4400 versus 1200) on a single battery charge.
- More heavily discounted: Has been available for much longer (launched in December 2008).
Reasons to prefer the Nikon D810:
- More detail: Has more megapixels (36.2 vs 24.4MP), which boosts linear resolution by 22%.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Scores markedly higher (9 points) in the DXO overall evaluation.
- More dynamic range: Captures a broader range of light and dark details (1.1 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (0.5 stops ISO advantage).
- Better jpgs: Has a more modern image processing engine (EXPEED 4 vs EXPEED).
- Broader imaging potential: Can capture not only stills but also 1080/60p video.
- Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (1229k vs 922k dots).
- More compact: Is smaller (146x123mm vs 160x157mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 280g or 22 percent) and is thus easier to take along.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- More affordable: Was introduced into a lower priced category (59 percent cheaper at launch).
- More modern: Reflects 5 years and 6 months of technical progress since the D3X launch.
If the number of relative strengths (bullet points above) is taken as a guide, the D810 is the clear winner of the contest (16 : 4 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Nikon D3X and the Nikon D810 place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing whether the two cameras rank among the cream of the crop.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D3X or the D810. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.
The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
