Fujifilm X-S10 vs X-T4
The Fujifilm X-S10 and the Fujifilm X-T4 are two digital cameras that were revealed to the public, respectively, in October 2020 and February 2020. Both the X-S10 and the X-T4 are mirrorless interchangeable lens cameras that are equipped with an APS-C sensor. Both cameras offer a resolution of 26 megapixels.
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-S10 and the Fujifilm X-T4? 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-S10 and the Fujifilm X-T4 are illustrated in the side-by-side display below. 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 X-S10 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 Fujifilm X-T4 is notably larger (17 percent) than the Fujifilm X-S10. Moreover, the X-T4 is markedly heavier (31 percent) than the X-S10. It is noteworthy in this context that the X-T4 is splash and dust-proof, while the X-S10 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Fujinon X Lens Catalog. Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.
Concerning battery life, the X-S10 gets 325 shots out of its NP-W126S battery, while the X-T4 can take 500 images on a single charge of its NP-W235 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

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 X-S10 was launched at a markedly lower price (by 41 percent) than the X-T4, 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.
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 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies and lenses.
Both cameras under consideration feature an APS-C sensor and have a format factor (sometimes also referred to as "crop factor") of 1.5. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 26 megapixels. This similarity in sensor specs implies that both the X-S10 and the X-T4 have the same pixel density, as well as the same pixel size. It should, however, be noted that the X-S10 is a somewhat more recent model (by 7 months) than the X-T4, and its sensor might have benefitted from technological advances during this time. 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 Fujifilm X-S10 has a native sensitivity range from ISO 160 to ISO 12800, which can be extended to ISO 80-51200. The Fujifilm X-T4 offers exactly the same ISO settings.
For many cameras, data on sensor performance has been reported by DXO Mark. 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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the X-T4 provides a faster frame rate than the X-S10. It can shoot movie footage at 4K/60p, while the X-S10 is limited to 4K/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the X-T4 offers a substantially higher resolution than the one in the X-S10 (3690k vs 2360k dots). The following table reports on some other key feature differences and similarities of the Fujifilm X-S10, the Fujifilm X-T4, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The X-S10 has one, while the X-T4 does not. While the built-in flash of the X-S10 is not very powerful, it can at times be useful as a fill-in light.Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.
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, both cameras under consideration feature an 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-S10 and the Fujifilm X-T4 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.
Concerning the storage of imaging data, both the X-S10 and the X-T4 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 X-S10 only has one slot. The X-T4 supports UHS-II cards (on both slots), while the X-S10 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-S10 and Fujifilm X-T4 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Fujifilm X-T4 (unlike the X-S10) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the X-S10 and the X-T4 are recent models that are part of the current product line-up. The X-T4 replaced the earlier Fujifilm X-T3, while the X-S10 does not have a direct predecessor. 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? Which of the two cameras – the Fujifilm X-S10 or the Fujifilm X-T4 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Fujifilm X-S10:
- More compact: Is smaller (126x85mm vs 135x93mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 142g or 23 percent) and hence easier to carry around.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- Faster data transfer: Supports a more advanced USB protocol (3.2 vs 3.1).
- More affordable: Was introduced into a lower priced category (41 percent cheaper at launch).
- More modern: Is somewhat more recent (announced 7 months after the X-T4).
Reasons to prefer the Fujifilm X-T4:
- Better video: Provides higher movie framerates (4K/60p versus 4K/30p).
- More detailed viewfinder: Has higher resolution electronic viewfinder (3690k vs 2360k dots).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.75x vs 0.62x).
- More detailed LCD: Has a higher resolution rear screen (1620k vs 1040k dots).
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (15 vs 8 flaps/sec) to capture the decisive moment.
- Longer lasting: Gets more shots (500 versus 325) out of a single battery charge.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
- More heavily discounted: Has been on the market for longer (launched in February 2020).
If the count of relative strengths (bullet points above) is taken as a measure, the X-T4 is the clear winner of the contest (12 : 6 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 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-S10 and the Fujifilm X-T4 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing whether the two cameras rank among the cream of the crop.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the X-S10 or the X-T4 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 where reviews by experts come in. 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 were established in reference to similarly priced cameras that were available in the market at the time of the review. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
