Fujifilm X-E4 vs Leica SL2
The Fujifilm X-E4 and the Leica SL2 are two digital cameras that were announced, respectively, in January 2021 and November 2019. Both the X-E4 and the SL2 are mirrorless interchangeable lens cameras that are based on an APS-C (X-E4) and a full frame (SL2) sensor. The Fujifilm has a resolution of 26 megapixels, whereas the Leica provides 46.7 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-E4 and the Leica SL2? 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-E4 and the Leica SL2 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 measures are rounded to the nearest millimeter.
The X-E4 can be obtained in two different colors (black, silver), while the SL2 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 Leica SL2 is considerably larger (77 percent) than the Fujifilm X-E4. Moreover, the SL2 is substantially heavier (162 percent) than the X-E4. It is noteworthy in this context that the SL2 is splash and dust-proof, while the X-E4 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.
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. 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 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-E4 was launched at a markedly lower price (by 86 percent) than the SL2, 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 size of the imaging sensor is a crucial determinant 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. 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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Fujifilm X-E4 features an APS-C sensor and the Leica SL2 a full frame sensor. The sensor area in the SL2 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 46.7MP, the SL2 offers a higher resolution than the X-E4 (26MP), but the SL2 nevertheless has larger individual pixels (pixel pitch of 4.30μm versus 3.76μm for the X-E4) due to its larger sensor. However, the X-E4 is a somewhat more recent model (by 1 year and 2 months) than the SL2, 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 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 Leica SL2 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SL2 for good quality output (200 dots per inch) amounts to 41.8 x 27.9 inches or 106.3 x 70.9 cm, for very good quality (250 dpi) 33.5 x 22.3 inches or 85 x 56.7 cm, and for excellent quality (300 dpi) 27.9 x 18.6 inches or 70.8 x 47.3 cm. The corresponding values for the Fujifilm X-E4 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-E4 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
Unlike the X-E4, the SL2 has the capacity to capture high quality composite images (187MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).
The Fujifilm X-E4 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 Leica SL2 are ISO 100 to ISO 50000, with the possibility to increase the ISO range to 50-50000.
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 cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the SL2 provides a faster frame rate than the X-E4. It can shoot movie footage at 4K/60p, while the Fujifilm is limited to 4K/30p.
Apart from body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the SL2 offers a substantially higher resolution than the one in the X-E4 (5760k vs 2360k dots). The table below summarizes some of the other core capabilities of the Fujifilm X-E4 and Leica SL2 in connection with corresponding information for a sample of similar cameras.
One feature that differentiates the SL2 and the X-E4 is in-body image stabilization (IBIS). The SL2 reduces the risk of handshake-induced blur with all attached lenses, while the X-E4 offers no blur reduction with lenses that themselves do not provide optical image stabilization.
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-E4 and the Leica SL2 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-E4 and the SL2 write their files to SDXC cards. The SL2 features dual card slots, which can be very useful in case a memory card fails. In contrast, the X-E4 only has one slot. The SL2 supports UHS-II cards (on both slots), while the X-E4 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-E4 and Leica SL2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SL2 has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The X-E4 lacks such a headphone port.
Studio photographers will appreciate that the Leica SL2 (unlike the X-E4) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the X-E4 and the SL2 are recent models that are part of the current product line-up. The SL2 replaced the earlier Leica SL (Typ 601), while the X-E4 followed on from the Fujifilm X-E3. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Fujifilm and Leica websites.

If the count of individual advantages (bullet points above) is taken as a guide, the SL2 is the clear winner of the contest (23 : 7 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.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the X-E4 or the SL2. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price 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.
