Fujifilm X-T4 vs Nikon D800
The Fujifilm X-T4 and the Nikon D800 are two digital cameras that were announced, respectively, in February 2020 and February 2012. The X-T4 is a mirrorless interchangeable lens camera, while the D800 is a DSLR. The cameras are based on an APS-C (X-T4) and a full frame (D800) sensor. The Fujifilm has a resolution of 26 megapixels, whereas the Nikon 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 Fujifilm X-T4 and the Nikon D800? 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 Fujifilm X-T4 and the Nikon D800. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter.
The X-T4 can be obtained in two different colors (black, silver), while the D800 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 D800 is considerably larger (43 percent) than the Fujifilm X-T4. Moreover, the D800 is substantially heavier (65 percent) than the X-T4. 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. 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-T4) and the Nikon Lens Catalog (D800). Mirrorless cameras, such as the Fujifilm X-T4, 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-T4 gets 500 shots out of its NP-W235 battery, while the D800 can take 900 images on a single charge of its EN-EL15 power pack. The power pack in the X-T4 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 obviously take relative prices into account. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The X-T4 was launched at a markedly lower price (by 43 percent) than the D800, 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 tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Fujifilm X-T4 features an APS-C sensor and the Nikon D800 a full frame sensor. The sensor area in the D800 is 135 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 36.2MP, the D800 offers a higher resolution than the X-T4 (26MP), but the D800 nevertheless has larger individual pixels (pixel pitch of 4.88μm versus 3.76μm for the X-T4) due to its larger sensor. However, the X-T4 is a much more recent model (by 8 years) than the D800, 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 X-T4 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Nikon D800 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D800 for good quality output (200 dots per inch) amounts to 36.8 x 24.6 inches or 93.5 x 62.4 cm, for very good quality (250 dpi) 29.4 x 19.6 inches or 74.8 x 49.9 cm, and for excellent quality (300 dpi) 24.5 x 16.4 inches or 62.3 x 41.6 cm. The corresponding values for the Fujifilm X-T4 are 31.2 x 20.8 inches or 79.2 x 52.8 cm for good quality, 25 x 16.6 inches or 63.4 x 42.3 cm for very good quality, and 20.8 x 13.9 inches or 52.8 x 35.2 cm for excellent quality prints.
The X-T4 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Fujifilm X-T4 has a native sensitivity range from ISO 160 to ISO 12800, which can be extended to ISO 80-51200. The corresponding ISO settings for the Nikon D800 are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 50-25600.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 X-T4 provides a higher video resolution than the D800. It can shoot video footage at 4K/60p, while the Nikon is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the X-T4 has an electronic viewfinder (3690k dots), while the D800 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 X-T4 has a higher magnification than the one of the D800 (0.75x vs 0.70x), 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-T4, the Nikon D800, and comparable cameras.
|9.||Nikon Z6 II||3690||Y||3.2||2100||tilting||Y||1/8000s||14.0||n||Y|
One feature that differentiates the X-T4 and the D800 is in-body image stabilization (IBIS). The X-T4 reduces the risk of handshake-induced blur with all attached lenses, while the D800 offers no blur reduction with lenses that themselves do not provide optical image stabilization.The X-T4 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 D800 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-T4 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-T4 and the Nikon D800 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-T4 writes its imaging data to SDXC cards, while the D800 uses Compact Flash or SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails. The X-T4 supports UHS-II cards (on both slots), while the D800 can use UHS-I cards.
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-T4 and Nikon D800 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the X-T4 offers wifi support, while the D800 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.
The X-T4 is a recent model that features in the current product line-up of Fujifilm. In contrast, the D800 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the D800 was succeeded by the Nikon D810. 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 how do things add up? Is the Fujifilm X-T4 better than the Nikon D800 or vice versa? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Fujifilm X-T4:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.

- More heavily discounted: Has been around for much longer (launched in February 2012).
If the count of individual advantages (bullet points above) is taken as a guide, the X-T4 is the clear winner of the match-up (21 : 9 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 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.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the X-T4 and the D800 in practical situations. 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 expert reviews 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 ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
