Fujifilm X-T20 versus Panasonic GX8

The Fujifilm X-T20 and the Panasonic Lumix DMC-GX8 are two digital cameras that were announced, respectively, in January 2017 and July 2015. Both the X-T20 and the GX8 are mirrorless interchangeable lens cameras that are based on an APS-C (X-T20) and a Four Thirds (GX8) sensor. The Fujifilm has a resolution of 24 megapixel, whereas the Panasonic provides 20.2 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-T20 vs Panasonic GX8

The physical size and weight of the Fujifilm X-T20 and the Panasonic GX8 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size 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-T20 – 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 GX8 is notably larger (6 percent) than the Fujifilm X-T20. Moreover, the GX8 is markedly heavier (27 percent) than the X-T20. It is noteworthy in this context that the GX8 is splash and dust-proof, while the X-T20 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 find an overview of optics for the two cameras in the Fujinon X Lens Catalog (X-T20) and the Micro Four Thirds Lens Catalog (GX8). 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-T20 gets 350 shots out of its NP-W126S battery, while the GX8 can take 330 images on a single charge of its DMW-BLC12 power pack.

Any camera purchase will naturally be influenced heavily by the price. 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-T20 was launched at a somewhat lower price (by 25 percent) than the GX8, which makes it more attractive for photographers on a tight budget. 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.

 

Sensor comparison: Fujifilm X-T20 vs Panasonic GX8

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 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Fujifilm X-T20 features an APS-C sensor and the Panasonic GX8 a Four Thirds sensor. The sensor area in the GX8 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-T20 has a native 3:2 aspect ratio, while the one in the GX8 offers a 4:3 aspect.

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

Fujifilm X-T20 and Panasonic GX8 sensor measures

With 24MP, the X-T20 offers a higher resolution than the GX8 (20.2MP), but the X-T20 nevertheless has larger individual pixels (pixel pitch of 3.92μm versus 3.34μm for the GX8) due to its larger sensor. Moreover, the X-T20 is a somewhat more recent model (by 1 year and 6 months) than the GX8, 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-T20 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

One difference between the cameras concerns the presence of an on-board flash. The X-T20 has one, while the GX8 does not. While the build-in flash of the X-T20 is not very powerful, it can at times be useful as a fill-in light.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the GX8 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 X-T20 and the GX8 write their imaging data to SDXC cards.

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (10 vs 8 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • 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 July 2015).

If the count of individual advantages (bullet points above) is taken as a guide, the GX8 emerges as the winner of the match-up (9 : 7 points). 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-T20 07:09 GX8

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the X-T20 or the GX8. 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 following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The above review scores should be interpreted with care, 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
