Fujifilm X-E3 versus Panasonic GX7

The Fujifilm X-E3 and the Panasonic Lumix DMC-GX7 are two digital cameras that were revealed to the public, respectively, in September 2017 and August 2013. Both the X-E3 and the GX7 are mirrorless interchangeable lens cameras that are based on an APS-C (X-E3) and a Four Thirds (GX7) 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-E3 vs Panasonic GX7

The side-by-side display below illustrates the physical size and weight of the Fujifilm X-E3 and the Panasonic GX7. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth 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 X-E3 – 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 GX7 is somewhat smaller (2 percent) than the Fujifilm X-E3. However, the GX7 is markedly heavier (19 percent) than the X-E3. In this context, it is worth noting that neither the X-E3 nor the GX7 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-E3) and the Micro Four Thirds Lens Catalog (GX7). 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.

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-E3 was somewhat cheaper (by 10 percent) than the GX7 at launch, but both cameras fall into the same price category. 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-E3 vs Panasonic GX7

The size of the sensor inside a digital camera is one of the key determinants 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. 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 Fujifilm X-E3 features an APS-C sensor and the Panasonic GX7 a Four Thirds sensor. The sensor area in the GX7 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-E3 has a native 3:2 aspect ratio, while the one in the GX7 offers a 4:3 aspect.

Fujifilm X-E3 and Panasonic GX7 sensor measures

With 24MP, the X-E3 offers a higher resolution than the GX7 (15.8MP), but the X-E3 nevertheless has larger individual pixels (pixel pitch of 3.92μm versus 3.77μm for the GX7) due to its larger sensor. Moreover, the X-E3 is a somewhat more recent model (by 4 years and 1 month) than the GX7, 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 X-E3 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The X-E3 is a current model that online retailers, such as amazon, will have in stock. In contrast, the GX7 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the GX7 was succeeded by the Panasonic GX85.

Review summary: Fujifilm X-E3 vs Panasonic GX7

So what conclusions can be drawn? Which of the two cameras – the Fujifilm X-E3 or the Panasonic GX7 – 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-E3:

  • More detail: Offers more megapixels (24 vs 15.8MP) with a 26% higher linear resolution.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Features a larger and more technologically advanced imaging sensor.
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • Faster burst: Shoots at higher frequency (8 vs 5 flaps/sec) to capture the decisive moment.
  • Less heavy: Is lighter (by 65g or 16 percent) and hence easier to carry around.
  • More modern: Reflects 4 years and 1 month of technical progress since the GX7 launch.

ilogo

Arguments in favor of the Panasonic Lumix DMC-GX7:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2760k vs 2360k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More heavily discounted: Has been around for much longer (launched in August 2013).

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 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.

X-E3 07:07 GX7

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-E3 or the GX7. 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.

Care should be taken when interpreting the review scores above, 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 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.
