Panasonic GX80 versus Fujifilm X-A3

The Panasonic Lumix DMC-GX80 (called Panasonic GX85 in some regions) and the Fujifilm X-A3 are two digital cameras that were officially introduced, respectively, in April 2016 and August 2016. Both the GX80 and the X-A3 are mirrorless interchangeable lens cameras that are based on a Four Thirds (GX80) and an APS-C (X-A3) sensor. The Panasonic has a resolution of 15.8 megapixel, whereas the Fujifilm provides 24 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: Panasonic GX80 vs Fujifilm X-A3

The physical size and weight of the Panasonic GX80 and the Fujifilm X-A3 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the GX80 – 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 Fujifilm X-A3 is notably smaller (10 percent) than the Panasonic GX80. Moreover, the X-A3 is markedly lighter (20 percent) than the GX80. In this context, it is worth noting that neither the GX80 nor the X-A3 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 Micro Four Thirds Lens Catalog (GX80) and the Fujinon X Lens Catalog (X-A3). 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 GX80 gets 290 shots out of its DMW-BLG10 battery, while the X-A3 can take 410 images on a single charge of its NP-W126S power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

The camera’s price is obviously a critical decision-making factor. 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. 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.

 

Sensor comparison: Panasonic GX80 vs Fujifilm X-A3

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 Panasonic GX80 features a Four Thirds sensor and the Fujifilm X-A3 an APS-C sensor. The sensor area in the X-A3 is 64 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.5. The sensor in the GX80 has a native 4:3 aspect ratio, while the one in the X-A3 offers a 3:2 aspect.

Panasonic GX80 and Fujifilm X-A3 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 pixel-units. 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 can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the GX80 provides a higher video resolution than the X-A3. It can shoot video footage at 4K/30p, while the Fujifilm is limited to 1080/60p.

 

Feature comparison: Panasonic GX80 vs Fujifilm X-A3

Beyond 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 table below summarizes some of the other core capabilities of the Panasonic GX80 and Fujifilm X-A3 in connection with corresponding information for a sample of similar cameras.

One feature that differentiates the GX80 and the X-A3 is in-body image stabilization (IBIS). The GX80 reduces the risk of handshake-induced blur with all attached lenses, while the X-A3 has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the GX80 features an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

Both the GX80 and the X-A3 write their imaging data to SDXC cards.

Both the GX80 and the X-A3 are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The GX80 replaced the earlier Panasonic GX7, while the X-A3 followed on from the Fujifilm X-A2.

Review summary: Panasonic GX80 vs Fujifilm X-A3

So how do things add up? Is the Panasonic GX80 better than the Fujifilm X-A3 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Reasons to prefer 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.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Sharper images: Has hand-shake reducing image stabilization build-in.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More heavily discounted: Has been on the market for longer (launched in April 2016).

ilogo

Advantages of the Fujifilm X-A3:

  • More detail: Has more megapixels (24 vs 15.8MP), which boosts linear resolution by 26%.
  • 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: Has a lower weight (by 87g or 20 percent) and is thus easier to take along.
  • Longer lasting: Gets more shots (410 versus 290) out of a single battery charge.
  • More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).
  • More modern: Was introduced somewhat (4 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the GX80 comes out slightly ahead of the X-A3 (8 : 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.

GX80 08:07 X-A3

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 GX80 or the X-A3 handle or 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 summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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.
