Fujifilm X-T4 vs Leica SL3

The Fujifilm X-T4 and the Leica SL3 are two enthusiast cameras that were officially introduced, respectively, in February 2020 and March 2024. Both the X-T4 and the Leica SL3 are mirrorless interchangeable lens cameras that are based on an APS-C (X-T4) and a full frame (Leica SL3) sensor. The Fujifilm has a resolution of 26 megapixels, whereas the Leica provides 60.3 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Fujifilm X-T4 and the Leica SL3. 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 measures are rounded to the nearest millimeter.

The X-T4 can be obtained in two different colors (black, silver), while the Leica SL3 is only available in black.

Compare X-T4 versus Leica SL3 top
Comparison X-T4 or Leica SL3 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Leica SL3 is notably larger (21 percent) than the Fujifilm X-T4. Moreover, the Leica SL3 is markedly heavier (27 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. 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.

Concerning battery life, the X-T4 gets 500 shots out of its Fujifilm NP-W235 battery, while the Leica SL3 can take 320 images on a single charge of its Leica BP-SCL6 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.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The X-T4 was launched at a markedly lower price (by 76 percent) than the Leica SL3, 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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. 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 Leica SL3 a full frame sensor. The sensor area in the Leica SL3 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.

Fujifilm X-T4 and Leica SL3 sensor measures

With 60.3MP, the Leica SL3 offers a higher resolution than the X-T4 (26MP), but the Leica SL3 nevertheless has marginally larger individual pixels (pixel pitch of 3.79μm versus 3.76μm for the X-T4) due to its larger sensor. Moreover, the Leica SL3 is a much more recent model (by 4 years) than the X-T4, and its sensor will have benefitted from technological advances during this time that further 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 SL3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Leica SL3 for good quality output (200 dots per inch) amounts to 47.6 x 31.7 inches or 120.9 x 80.5 cm, for very good quality (250 dpi) 38.1 x 25.3 inches or 96.7 x 64.4 cm, and for excellent quality (300 dpi) 31.7 x 21.1 inches or 80.6 x 53.6 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 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 Leica SL3 are ISO 100 to ISO 100000, with the possibility to increase the ISO range to 50-100000.

In terms of underlying technology, the X-T4 is build around a BSI-CMOS sensor, while the Leica SL3 uses a CMOS imager. The X-T4 uses Fujifilm's X-Trans layout of photosites, while the Leica SL3 employs the more common Bayer array.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One feature that is present on the Leica SL3, but is missing on the X-T4 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

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 Leica SL3 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, 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-T4 and the Leica SL3 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 Leica SL3 uses CFexpress (type B) or SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails. Both cameras support UHS-II cards, which provide for Ultra High Speed data transfer of up to 312 MB/s.

It is notable that the Leica SL3 has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The X-T4 lacks such a headphone port.

Studio photographers will appreciate that the Fujifilm X-T4 (unlike the Leica SL3) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The Leica SL3 is a recent model that features in the current product line-up of Leica. In contrast, the X-T4 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the X-T4 was succeeded by the Fujifilm X-T5. Further information on the features and operation of the X-T4 and Leica SL3 can be found, respectively, in the Fujifilm X-T4 Manual (free pdf) or the online Leica SL3 Manual.

Review summary

So how do things add up? Is the Fujifilm X-T4 better than the Leica SL3 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Reasons to prefer the Fujifilm X-T4:

  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (15 vs 5 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (135x93mm vs 141x108mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 162g or 21 percent) and hence easier to carry around.
  • Longer lasting: Can take more shots (500 versus 320) on a single battery charge.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • More affordable: Was introduced into a lower priced category (76 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in February 2020).

ilogo

Advantages of the Leica SL3:

  • More detail: Has more megapixels (60.3 vs 26MP), which boosts linear resolution by 52%.
  • Better image quality: Is equipped with a larger and more technologically advanced sensor.
  • Richer colors: The sensor size advantage translates into images with better, more accurate colors.
  • More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
  • Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
  • Better video: Provides higher definition movie capture (8K/30p vs 4K/60p).
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (5760k vs 3690k dots).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.76x vs 0.75x).
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (2333k vs 1620k dots).
  • More solid recording: Has a full-sized HDMI port for a sturdy connection to an external recorder.
  • More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
  • More modern: Reflects 4 years of technical progress since the X-T4 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the Leica SL3 is the clear winner of the contest (15 : 9 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 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.

X-T4 09:15 Leica SL3

How about other alternatives? Do the specifications of the Fujifilm X-T4 and the Leica SL3 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 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 Leica SL3 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

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. Also, please note that some of the review sites have changed their methodology and reporting over time.
