Fujifilm X-A3 vs Panasonic GH5s
The Fujifilm X-A3 and the Panasonic Lumix DC-GH5s are two digital cameras that were revealed to the public, respectively, in August 2016 and January 2018. Both the X-A3 and the GH5s are mirrorless interchangeable lens cameras that are based on an APS-C (X-A3) and a Four Thirds (GH5s) sensor. The Fujifilm has a resolution of 24 megapixels, whereas the Panasonic provides 9.9 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-A3 and the Panasonic Lumix DC-GH5s? 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-A3 and the Panasonic GH5s are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.
The X-A3 can be obtained in three different colors (silver, brown, pink), while the GH5s 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 Panasonic GH5s is considerably larger (74 percent) than the Fujifilm X-A3. Moreover, the GH5s is substantially heavier (95 percent) than the X-A3. It is noteworthy in this context that the GH5s is splash and dust-proof, while the X-A3 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. 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-A3) and the Micro Four Thirds Lens Catalog (GH5s). 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-A3 gets 410 shots out of its NP-W126S battery, while the GH5s can take 440 images on a single charge of its DMW-BLF19 power pack. The power pack in the X-A3 can be charged via the USB port, so that it is not always necessary to take the battery charger along 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 obviously take relative prices into account. 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-A3 was launched at a markedly lower price (by 84 percent) than the GH5s, which puts it into a different market segment. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Fujifilm X-A3 features an APS-C sensor and the Panasonic GH5s a Four Thirds sensor. The sensor area in the GH5s 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-A3 has a native 3:2 aspect ratio, while the one in the GH5s offers a 4:3 aspect.
With 24MP, the X-A3 offers a higher resolution than the GH5s (9.9MP), but the X-A3 has smaller individual pixels (pixel pitch of 3.92μm versus 4.77μm for the GH5s). Moreover, the GH5s is a somewhat more recent model (by 1 year and 4 months) than the X-A3, 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 the GH5s has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Fujifilm X-A3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X-A3 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Panasonic GH5s are 18.4 x 13.5 inches or 46.7 x 34.3 cm for good quality, 14.7 x 10.8 inches or 37.4 x 27.4 cm for very good quality, and 12.3 x 9 inches or 31.2 x 22.9 cm for excellent quality prints.
The Fujifilm X-A3 has a native sensitivity range from ISO 200 to ISO 6400, which can be extended to ISO 100-25600. The corresponding ISO settings for the Panasonic Lumix DC-GH5s are ISO 160 to ISO 51200, with the possibility to increase the ISO range to 80-204800.
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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

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 GH5s provides a better video resolution than the X-A3. It can shoot movie footage at 4K/60p, while the Fujifilm is limited to 1080/60p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the GH5s has an electronic viewfinder (3680k dots), which can be very helpful when shooting in bright sunlight. In contrast, the X-A3 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Fujifilm X-A3 and Panasonic GH5s in connection with corresponding information for a sample of similar cameras.
One difference between the cameras concerns the presence of an on-board flash. The X-A3 has one, while the GH5s does not. While the built-in flash of the X-A3 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-A3 and the Panasonic GH5s 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-A3 and the GH5s write their files to SDXC cards. The GH5s features dual card slots, which can be very useful in case a memory card fails. In contrast, the X-A3 only has one slot. The GH5s supports UHS-II cards (on both slots), while the X-A3 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-A3 and Panasonic Lumix DC-GH5s and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GH5s has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The X-A3 lacks such a headphone port.
Studio photographers will appreciate that the Panasonic GH5s (unlike the X-A3) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The GH5s is a recent model that features in the current product line-up of Panasonic. In contrast, the X-A3 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the X-A3 was succeeded by the Fujifilm X-A5. 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 the Fujifilm X-A3 better than the Panasonic GH5s or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Fujifilm X-A3:
- More detail: Offers more megapixels (24 vs 9.9MP) with a 58% higher linear resolution.
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- More compact: Is smaller (117x67mm vs 139x98mm) and thus needs less room in the bag.

- Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
- More modern: Was introduced somewhat (1 year and 4 months) more recently.
If the count of individual advantages (bullet points above) is taken as a guide, the GH5s is the clear winner of the contest (18 : 8 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. 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.

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-A3 or the GH5s 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 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], 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 are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
