Fujifilm X-T4 vs X20
The Fujifilm X-T4 and the Fujifilm X20 are two digital cameras that were announced, respectively, in February 2020 and January 2013. The X-T4 is a mirrorless interchangeable lens camera, while the X20 is a fixed lens compact. The cameras are based on an APS-C (X-T4) and a 2/3 (X20) sensor. The X-T4 has a resolution of 26 megapixels, whereas the X20 provides 12 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 Fujifilm X20? 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-T4 and the Fujifilm X20 are illustrated 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 measures are rounded to the nearest millimeter.
Both cameras are available in two different colors (black, silver).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Fujifilm X20 is considerably smaller (35 percent) than the Fujifilm X-T4. It is worth mentioning in this context that the X-T4 is splash and dust resistant, while the X20 does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the X20 has a lens built in, whereas the X-T4 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the X-T4 and their specifications in the Fujinon X Lens Catalog.
Concerning battery life, the X-T4 gets 500 shots out of its NP-W235 battery, while the X20 can take 270 images on a single charge of its NP-50 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.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The X20 was launched at a lower price than the X-T4, despite having a lens built in. 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 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 Fujifilm X20 a 2/3 sensor. The sensor area in the X20 is 84 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 3.9. The sensor in the X-T4 has a native 3:2 aspect ratio, while the one in the X20 offers a 4:3 aspect.
With 26MP, the X-T4 offers a higher resolution than the X20 (12MP), but the X-T4 nevertheless has larger individual pixels (pixel pitch of 3.76μm versus 2.20μm for the X20) due to its larger sensor. Moreover, the X-T4 is a much more recent model (by 7 years and 1 month) than the X20, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.
The resolution advantage of the Fujifilm X-T4 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X-T4 for good quality output (200 dots per inch) amounts to 31.2 x 20.8 inches or 79.2 x 52.8 cm, for very good quality (250 dpi) 25 x 16.6 inches or 63.4 x 42.3 cm, and for excellent quality (300 dpi) 20.8 x 13.9 inches or 52.8 x 35.2 cm. The corresponding values for the Fujifilm X20 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.
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 Fujifilm X20 are ISO 100 to ISO 12800 (no boost).
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 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-T4 provides a higher video resolution than the X20. It can shoot video footage at 4K/60p, while the X20 is limited to 1080/60p.
Beyond 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 X20 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 following table reports on some other key feature differences and similarities of the Fujifilm X-T4, the Fujifilm X20, and comparable cameras.
One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The X-T4 has a touchscreen, while the X20 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.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 X20 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 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.
Concerning the storage of imaging data, both the X-T4 and the X20 write their files to SDXC cards. The X-T4 features dual card slots, which can be very useful in case a memory card fails. In contrast, the X20 only has one slot. The X-T4 supports UHS-II cards (on both slots), while the X20 cannot take advantage of Ultra High Speed SD 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 Fujifilm X20 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the X-T4 has a microphone port, which is missing on the X20. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Studio photographers will appreciate that the Fujifilm X-T4 (unlike the X20) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The X-T4 is a recent model that features in the current product line-up of Fujifilm. In contrast, the X20 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the X20 was succeeded by the Fujifilm X30. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Fujifilm website.
So what conclusions can be drawn? Is there a clear favorite between the Fujifilm X-T4 and the Fujifilm X20? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More heavily discounted: Has been around for much longer (launched in January 2013).
If the number of relative strengths (bullet points above) is taken as a guide, the X-T4 is the clear winner of the match-up (28 : 7 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 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 Fujifilm X-T4 and the Fujifilm X20 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Travel-Zoom 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-T4 or the X20 perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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 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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
