Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm X-T100 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 physical size and weight of the Fujifilm X-T100 and the Nikon D850 are illustrated in the side-by-side display below. 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.
The X-T100 can be obtained in three different colors (black, silver, gold), while the D850 is only available in black.
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 (80 percent) than the Fujifilm X-T100. Moreover, the D850 is substantially heavier (124 percent) than the X-T100. It is noteworthy in this context that the D850 is splash and dust-proof, while the X-T100 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 Fujinon X Lens Catalog (X-T100) and the Nikon Lens Catalog (D850). Mirrorless cameras, such as the Fujifilm X-T100, have moreover the advantage that they have a relatively short flange to focal plane distance and can thus use many lenses from other systems via adapters.
Concerning battery life, the X-T100 gets 430 shots out of its NP-W126S battery, while the D850 can take 1840 images on a single charge of its EN-EL15a power pack. The power pack in the X-T100 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

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 X-T100 was launched at a markedly lower price (by 82 percent) than the D850, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 size of the imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Fujifilm X-T100 features an APS-C sensor and the Nikon D850 a full frame sensor. The sensor area in the D850 is 133 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 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 X-T100 (24MP), but the D850 nevertheless has larger individual pixels (pixel pitch of 4.35μm versus 3.92μm for the X-T100) due to its larger sensor. However, the X-T100 is a somewhat more recent model (by 9 months) than the D850, and its sensor might 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 Fujifilm X-T100 are 30 x 20 inches or 76.2 x 50.8 cm for good quality, 24 x 16 inches or 61 x 40.6 cm for very good quality, and 20 x 13.3 inches or 50.8 x 33.9 cm for excellent quality prints.
The X-T100 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Fujifilm X-T100 has a native sensitivity range from ISO 200 to ISO 12800, which can be extended to ISO 100-51200. 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 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"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the D850 provides a faster frame rate than the X-T100. It can shoot movie footage at 4K/30p, while the Fujifilm is limited to 4K/15p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the X-T100 has an electronic viewfinder (2360k dots), while the D850 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the D850 has a higher magnification than the one of the X-T100 (0.75x vs 0.62x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Fujifilm X-T100 and Nikon D850 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The X-T100 has one, while the D850 does not. While the built-in flash of the X-T100 is not very powerful, it can at times be useful as a fill-in light.The X-T100 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the D850 does not have a selfie-screen.
The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the X-T100 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The Fujifilm X-T100 and the Nikon D850 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 X-T100 writes its imaging data to SDXC 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 X-T100 only has one slot. The D850 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the X-T100 can use UHS-I cards (up to 104 MB/s).
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 Fujifilm X-T100 and Nikon D850 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D850 has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The X-T100 lacks such a headphone port.
Studio photographers will appreciate that the Nikon D850 (unlike the X-T100) 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 X-T100 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the X-T100 was succeeded by the Fujifilm X-T200. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Fujifilm and Nikon websites.
So what conclusions can be drawn? Is the Fujifilm X-T100 better than the Nikon D850 or vice versa? The listing below highlights the relative strengths of the two models.

- More heavily discounted: Has been on the market for longer (launched in July 2017).
If the number of relative strengths (bullet points above) is taken as a guide, the D850 is the clear winner of the contest (23 : 12 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 Fujifilm X-T100 and the Nikon D850 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR Camera listings 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 X-T100 or the D850 perform in practice. 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 review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
