Fujifilm X-T20 vs Nikon D4S
The Fujifilm X-T20 and the Nikon D4S are two digital cameras that were revealed to the public, respectively, in January 2017 and February 2014. The X-T20 is a mirrorless interchangeable lens camera, while the D4S is a DSLR. The cameras are based on an APS-C (X-T20) and a full frame (D4S) sensor. The Fujifilm has a resolution of 24 megapixels, whereas the Nikon provides 16.2 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 Fujifilm X-T20 and the Nikon D4S? 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 Fujifilm X-T20 and the Nikon D4S 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.
The X-T20 can be obtained in two different colors (black, silver), while the D4S 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 D4S is considerably larger (156 percent) than the Fujifilm X-T20. Moreover, the D4S is substantially heavier (252 percent) than the X-T20. It is noteworthy in this context that the D4S is splash and dust-proof, while the X-T20 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-T20) and the Nikon Lens Catalog (D4S). Mirrorless cameras, such as the Fujifilm X-T20, 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-T20 gets 350 shots out of its NP-W126S battery, while the D4S can take 3020 images on a single charge of its EN-EL18a power pack. As can be seen in the images above, the D4S has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. The power pack in the X-T20 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 manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The X-T20 was launched at a markedly lower price (by 86 percent) than the D4S, 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.
Of the two cameras under consideration, the Fujifilm X-T20 features an APS-C sensor and the Nikon D4S a full frame sensor. The sensor area in the D4S is 134 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.
Despite having a smaller sensor, the Fujifilm X-T20 offers a higher resolution of 24 megapixels, compared with 16.2 MP of the Nikon D4S. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.92μm versus 7.29μm for the D4S). However, it should be noted that the X-T20 is much more recent (by 2 years and 10 months) than the D4S, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the X-T20 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Fujifilm X-T20 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X-T20 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Nikon D4S are 24.6 x 16.4 inches or 62.6 x 41.7 cm for good quality, 19.7 x 13.1 inches or 50.1 x 33.3 cm for very good quality, and 16.4 x 10.9 inches or 41.7 x 27.8 cm for excellent quality prints.
The X-T20 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Fujifilm X-T20 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 D4S are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-409600.
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 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. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the X-T20 provides a higher video resolution than the D4S. It can shoot video footage at 4K/30p, while the Nikon is limited to 1080/60p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the X-T20 has an electronic viewfinder (2360k dots), while the D4S 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 D4S has a higher magnification than the one of the X-T20 (0.70x vs 0.62x), 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 Fujifilm X-T20, the Nikon D4S, and comparable cameras.
One difference between the cameras concerns the presence of an on-board flash. The X-T20 has one, while the D4S does not. While the built-in flash of the X-T20 is not very powerful, it can at times be useful as a fill-in light.
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-T20 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-T20 and the Nikon D4S 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-T20 writes its imaging data to SDXC cards, while the D4S uses Compact Flash or XQD cards. The D4S features dual card slots, which can be very useful in case a memory card fails. In contrast, the X-T20 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 Fujifilm X-T20 and Nikon D4S and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

| NFC |
It is notable that the X-T20 offers wifi support, while the D4S does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Studio photographers will appreciate that the Nikon D4S (unlike the X-T20) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the X-T20 and the D4S have been discontinued, but can regularly be found used on eBay. The D4S was replaced by the Nikon D5, while the X-T20 was followed by the Fujifilm X-T100. 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 is the bottom line? Is there a clear favorite between the Fujifilm X-T20 and the Nikon D4S? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

If the number of relative strengths (bullet points above) is taken as a guide, the D4S comes out slightly ahead of the X-T20 (18 : 17 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.

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 X-T20 or the D4S. 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 (amateurphotographer [AP], cameralabs [CL], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
