Canon 400D vs Nikon D850
The Canon EOS 400D (called Canon XTi in some regions) and the Nikon D850 are two digital cameras that were revealed to the public, respectively, in August 2006 and July 2017. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (400D) and a full frame (D850) sensor. The Canon has a resolution of 10.1 megapixels, whereas the Nikon provides 45.4 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 Canon EOS 400D and the Nikon D850? 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.
The side-by-side display below illustrates the physical size and weight of the Canon 400D and the Nikon D850. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. 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 D850 is considerably larger (70 percent) than the Canon 400D. Moreover, the D850 is substantially heavier (81 percent) than the 400D. It is noteworthy in this context that the D850 is splash and dust-proof, while the 400D does not feature any corresponding weather-sealing.
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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (400D) and the Nikon Lens Catalog (D850).

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 400D was launched at a markedly lower price (by 76 percent) than the D850, 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. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels in a sensor of the same technological generation. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon 400D features an APS-C sensor and the Nikon D850 a full frame sensor. The sensor area in the D850 is 161 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 45.4MP, the D850 offers a higher resolution than the 400D (10.1MP), but the D850 has smaller individual pixels (pixel pitch of 4.35μm versus 5.71μm for the 400D). Yet, the D850 is a much more recent model (by 10 years and 11 months) than the 400D, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the D850 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Nikon D850 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D850 for good quality output (200 dots per inch) amounts to 41.3 x 27.5 inches or 104.9 x 69.9 cm, for very good quality (250 dpi) 33 x 22 inches or 83.9 x 55.9 cm, and for excellent quality (300 dpi) 27.5 x 18.3 inches or 69.9 x 46.6 cm. The corresponding values for the Canon 400D are 19.4 x 13 inches or 49.4 x 32.9 cm for good quality, 15.6 x 10.4 inches or 39.5 x 26.3 cm for very good quality, and 13 x 8.6 inches or 32.9 x 21.9 cm for excellent quality prints.
The Canon EOS 400D has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Nikon D850 are ISO 64 to ISO 25600, with the possibility to increase the ISO range to 32-102400.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under consideration, the D850 offers substantially better image quality than the 400D (overall score 38 points higher). The advantage is based on 4.3 bits higher color depth, 3.8 EV in additional dynamic range, and 2 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.
|Nikon D850||Full Frame||45.4||8256||5504||4K/30p||26.4||14.8||2660||100|
|Canon 5DS||Full Frame||50.3||8688||5792||1080/30p||24.7||12.4||2381||87|
|Canon 5DS R||Full Frame||50.3||8688||5792||1080/30p||24.6||12.4||2308||86|
|Nikon D5||Full Frame||20.7||5588||3712||4K/30p||25.1||12.3||2343||88|
|Nikon D810||Full Frame||36.2||7360||4912||1080/60p||25.7||14.8||2853||97|
|Nikon D610||Full Frame||24.2||6016||4016||1080/30p||25.1||14.4||2925||94|
Many modern cameras are not only capable of taking still images, but also of capturing video footage. The D850 indeed provides for movie recording, while the 400D does not. The highest resolution format that the D850 can use is 4K/30p.
Apart from body and sensor, cameras can and do differ across a range of features. The 400D and the D850 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 viewfinder in the D850 offers a wider field of view (100%) than the one in the 400D (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the D850 has a higher magnification (0.75x vs 0.49x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Canon 400D, the Nikon D850, and comparable cameras.
|Canon 5DS R||optical||Y||3.2||1040||fixed||n||1/8000s||5.0||n||n|
One difference between the cameras concerns the presence of an on-board flash. The 400D has one, while the D850 does not. While the built-in flash of the 400D is not very powerful, it can at times be useful as a fill-in light.
The Nikon D850 has 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 400D writes its imaging data to Compact Flash cards, while the D850 uses SDHC or XQD cards. The D850 features dual card slots, which can be very useful in case a memory card fails. In contrast, the 400D only has one slot.
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 Canon EOS 400D and Nikon D850 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.
| WiFi |
|Canon 5DS R||Y||mono||mono||Y||-||mini||3.0||-||-||-|
It is notable that the D850 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 400D does not provide wifi capability.
Studio photographers will appreciate that the Nikon D850 (unlike the 400D) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The D850 is a recent model that features in the current product line-up of Nikon. In contrast, the 400D has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the 400D was succeeded by the Canon 450D. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Nikon websites.
So what is the bottom line? Is there a clear favorite between the Canon 400D and the Nikon D850? Which camera is better? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Canon EOS 400D:

If the count of individual advantages (bullet points above) is taken as a guide, the D850 is the clear winner of the contest (26 : 6 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 Canon 400D and the Nikon D850 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the 400D or the D850 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
