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 announced, 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. You can also toggle the display 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 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 adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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.

Any camera purchase will naturally be influenced heavily by the price. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Panasonic GX80 vs Fujifilm X-A3

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. 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 more expensive and lead to bigger and heavier cameras 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.

In terms of underlying technology, both cameras are build around CMOS sensors.

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.

GX80 versus X-A3 MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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 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 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.

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 silent shooting and higher burst speeds 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 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 what conclusions can be drawn? Which of the two cameras – the Panasonic GX80 or the Fujifilm X-A3 – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Advantages 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.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Sharper images: Has hand-shake reducing image stabilization build-in.
  • More heavily discounted: Has been on the market for longer (launched in April 2016).

ilogo

Reasons to prefer 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 number of relative strengths (bullet points above) is taken as a guide, the match-up finishes in a tie (7 points each). 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 07:07 X-A3

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the GX80 and the X-A3 in practical situations. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate. This is why expert reviews are important. The adjacent table relays the overall verdicts of several of the most popular 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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
