Fujifilm X-E4 vs Panasonic GX9
The Fujifilm X-E4 and the Panasonic Lumix DC-GX9 are two digital cameras that were officially introduced, respectively, in January 2021 and February 2018. Both the X-E4 and the GX9 are mirrorless interchangeable lens cameras that are based on an APS-C (X-E4) and a Four Thirds (GX9) sensor. The Fujifilm has a resolution of 26 megapixels, whereas the Panasonic provides 20.2 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 Panasonic Lumix DC-GX9? 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-E4 and the Panasonic GX9. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. 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 Panasonic GX9 is somewhat larger (1 percent) than the Fujifilm X-E4. Moreover, the GX9 is markedly heavier (12 percent) than the X-E4. In this context, it is worth noting that neither the X-E4 nor the GX9 are weather-sealed.
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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Fujinon X Lens Catalog (X-E4) and the Micro Four Thirds Lens Catalog (GX9). 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-E4 gets 380 shots out of its NP-W126S battery, while the GX9 can take 260 images on a single charge of its DMW-BLG10 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. 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 naturally be influenced heavily by the price. 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 two cameras under review were launched at the same price and fall into the same 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The size of the sensor inside a digital camera is one of the key determinants 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Fujifilm X-E4 features an APS-C sensor and the Panasonic GX9 a Four Thirds sensor. The sensor area in the GX9 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-E4 has a native 3:2 aspect ratio, while the one in the GX9 offers a 4:3 aspect.
With 26MP, the X-E4 offers a higher resolution than the GX9 (20.2MP), but the X-E4 nevertheless has larger individual pixels (pixel pitch of 3.76μm versus 3.34μm for the GX9) due to its larger sensor. Moreover, the X-E4 is a much more recent model (by 2 years and 11 months) than the GX9, 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-E4 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X-E4 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 Panasonic GX9 are 25.9 x 19.4 inches or 65.8 x 49.4 cm for good quality, 20.7 x 15.6 inches or 52.7 x 39.5 cm for very good quality, and 17.3 x 13 inches or 43.9 x 32.9 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.
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 Panasonic Lumix DC-GX9 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 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 have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (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 GX9 offers a higher resolution than the one in the X-E4 (2760k vs 2360k dots). The table below summarizes some of the other core capabilities of the Fujifilm X-E4 and Panasonic GX9 in connection with corresponding information for a sample of similar cameras.

One feature that differentiates the GX9 and the X-E4 is in-body image stabilization (IBIS). The GX9 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 Panasonic GX9 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 GX9 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
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 Panasonic Lumix DC-GX9 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the X-E4 has a microphone port, which is missing on the GX9. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Both the X-E4 and the GX9 are recent models that are part of the current product line-up. The GX9 replaced the earlier Panasonic GX8, 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 Panasonic websites.
So how do things add up? Is there a clear favorite between the Fujifilm X-E4 and the Panasonic GX9? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

- Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.62x).
- Faster burst: Shoots at higher frequency (9 vs 8 flaps/sec) to capture the decisive moment.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- More heavily discounted: Has been around for much longer (launched in February 2018).
If the count of individual advantages (bullet points above) is taken as a guide, the X-E4 is the clear winner of the match-up (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 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-E4 and the Panasonic GX9 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 says little about, for example, the shooting experience and imaging performance of the X-E4 and the GX9 in practical situations. 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 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. Thus, a score needs to be put into the context of the launch date and the launch price 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
