Fujifilm X-A3 versus Panasonic GX80

The Fujifilm X-A3 and the Panasonic Lumix DMC-GX80 (labelled Panasonic GX85 in some countries) are two digital cameras that were officially introduced, respectively, in August 2016 and April 2016. Both the X-A3 and the GX80 are mirrorless interchangeable lens cameras that are based on an APS-C (X-A3) and a Four Thirds (GX80) sensor. The Fujifilm has a resolution of 24 megapixel, whereas the Panasonic provides 15.8 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Fujifilm X-A3 vs Panasonic GX80

The side-by-side display below illustrates the physical size and weight of the Fujifilm X-A3 and the Panasonic GX80. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the X-A3 – represents 100 percent across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GX80 is notably larger (10 percent) than the Fujifilm X-A3. Moreover, the GX80 is markedly heavier (26 percent) than the X-A3. In this context, it is worth noting that neither the X-A3 nor the GX80 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 find an overview of optics for the two cameras in the Fujinon X Lens Catalog (X-A3) and the Micro Four Thirds Lens Catalog (GX80). 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 GX80 can take 290 images on a single charge of its DMW-BLG10 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The X-A3 was launched at a markedly lower price (by 50 percent) than the GX80, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Fujifilm X-A3 vs Panasonic GX80

The size of the imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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-A3 features an APS-C sensor and the Panasonic GX80 a Four Thirds sensor. The sensor area in the GX80 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 GX80 offers a 4:3 aspect.

Fujifilm X-A3 and Panasonic GX80 sensor measures

With 24MP, the X-A3 offers a higher resolution than the GX80 (15.8MP), but the X-A3 nevertheless has larger individual pixels (pixel pitch of 3.92μm versus 3.77μm for the GX80) due to its larger sensor. Moreover, the X-A3 is a somewhat more recent model (by 4 months) than the GX80, 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 GX80 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

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, but the GX80 provides a better video resolution than the X-A3. It can shoot movie footage at 4K/30p, while the Fujifilm is limited to 1080/60p.

 

Feature comparison: Fujifilm X-A3 vs Panasonic GX80

Apart from body and sensor, cameras can and do differ across a range of features. For example, the GX80 has an electronic viewfinder (2765k 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 following table reports on some other key feature differences and similarities of the Fujifilm X-A3, the Panasonic GX80, and comparable cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Review summary: Fujifilm X-A3 vs Panasonic GX80

So what conclusions can be drawn? Which of the two cameras – the Fujifilm X-A3 or the Panasonic GX80 – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Reasons to prefer the Fujifilm X-A3:

  • More detail: Offers more megapixels (24 vs 15.8MP) with a 26% higher linear resolution.
  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better low-light imaging: Features bigger pixels on a larger sensor for better high-ISO images.
  • Less heavy: Is lighter (by 87g or 20 percent) and hence easier to carry around.
  • Longer lasting: Can take more shots (410 versus 290) on a single battery charge.
  • More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).
  • More modern: Is somewhat more recent (announced 4 months after the GX80).

ilogo

Arguments in favor of the Panasonic Lumix DMC-GX80:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • Easier framing: Has an electronic viewfinder for image framing and settings control.
  • Faster burst: Shoots at higher frequency (8 vs 6 flaps/sec) to capture the decisive moment.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More heavily discounted: Has been on the market for longer (launched in April 2016).

If the number of relative strengths (bullet points above) is taken as a guide, the X-A3 comes out slightly ahead of the GX80 (7 : 6 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.

X-A3 07:06 GX80

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the X-A3 or the GX80. 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 expert reviews are important. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
