Fujifilm X-T4 vs Leica D-LUX 7
The Fujifilm X-T4 and the Leica D-LUX 7 are two enthusiast cameras that were announced, respectively, in February 2020 and November 2018. The X-T4 is a mirrorless interchangeable lens camera, while the D-LUX 7 is a fixed lens compact. The cameras are based on an APS-C (X-T4) and a Four Thirds (D-LUX 7) sensor. The Fujifilm has a resolution of 26 megapixels, whereas the Leica provides 16.8 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 Leica D-LUX 7? 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 Leica D-LUX 7. 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 D-LUX 7 is only available in silver.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Leica D-LUX 7 is considerably smaller (40 percent) than the Fujifilm X-T4. It is worth mentioning in this context that the X-T4 is splash and dust resistant, while the D-LUX 7 does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the D-LUX 7 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 D-LUX 7 can take 300 images on a single charge of its BP-DC15 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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.

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 D-LUX 7 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.
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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Fujifilm X-T4 features an APS-C sensor and the Leica D-LUX 7 a Four Thirds sensor. The sensor area in the D-LUX 7 is 39 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the X-T4 has a native 3:2 aspect ratio, while the one in the D-LUX 7 offers a 4:3 aspect. The D-LUX 7 has the particularity of featuring a switch that allows to toggle between multiple aspect ratios, while maintaining the same field of view and full image resolution.
With 26MP, the X-T4 offers a higher resolution than the D-LUX 7 (16.8MP), but the X-T4 nevertheless has marginally larger individual pixels (pixel pitch of 3.76μm versus 3.66μm for the D-LUX 7) due to its larger sensor. Moreover, the X-T4 is a somewhat more recent model (by 1 year and 3 months) than the D-LUX 7, and its sensor might 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 Leica D-LUX 7 are 23.7 x 17.8 inches or 60.1 x 45.1 cm for good quality, 18.9 x 14.2 inches or 48.1 x 36.1 cm for very good quality, and 15.8 x 11.8 inches or 40.1 x 30.1 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 Leica D-LUX 7 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). 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 higher frame rate than the D-LUX 7. It can shoot video footage at 4K/60p, while the Leica is limited to 4K/30p.
Apart from body and sensor, cameras can and do differ across a range of features. The two cameras under consideration 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 D-LUX 7 (3690k vs 2764k dots). The table below summarizes some of the other core capabilities of the Fujifilm X-T4 and Leica D-LUX 7 in connection with corresponding information for a sample of similar cameras.

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 D-LUX 7 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-T4 and the D-LUX 7 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 D-LUX 7 only has one slot. The X-T4 supports UHS-II cards (on both slots), while the D-LUX 7 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 Leica D-LUX 7 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 D-LUX 7. 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 D-LUX 7) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the X-T4 and the D-LUX 7 are recent models that are part of the current product line-up. The D-LUX 7 replaced the earlier Leica D-LUX Typ 109, while the X-T4 followed on from the Fujifilm X-T3. 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.
So what is the bottom line? Is there a clear favorite between the Fujifilm X-T4 and the Leica D-LUX 7? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

If the count of relative strengths (bullet points above) is taken as a measure, the X-T4 is the clear winner of the match-up (23 : 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 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.
How about other alternatives? Do the specifications of the Fujifilm X-T4 and the Leica D-LUX 7 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the X-T4 or the D-LUX 7 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.
This is why hands-on reviews by experts 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], 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 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
