Body comparison

An illustration of the physical size and weight of the Fujifilm GFX 100S and the Panasonic GH6 is provided 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 width, height and depth measures are rounded to the nearest millimeter.

Size Fujifilm GFX 100S vs Panasonic GH6
Compare GFX 100S versus GH6 top
Comparison GFX 100S or GH6 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GH6 is notably smaller (12 percent) than the Fujifilm GFX 100S. Moreover, the GH6 is markedly lighter (9 percent) than the GFX 100S. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the GFX 100S gets 460 shots out of its Fujifilm NP-W235 battery, while the GH6 can take 360 images on a single charge of its Panasonic DMW-BLK22 power pack. The power pack in the GFX 100S can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Any camera decision will obviously take relative prices into account. 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 GH6 was launched at a markedly lower price (by 63 percent) than the GFX 100S, 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

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. 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 Fujifilm GFX 100S features a medium format sensor and the Panasonic GH6 a Four Thirds sensor. The sensor area in the GH6 is 84 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 0.79 and 2.0. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Fujifilm GFX 100S and Panasonic GH6 sensor measures

With 101.8MP, the GFX 100S offers a higher resolution than the GH6 (25MP), but the GFX 100S nevertheless has larger individual pixels (pixel pitch of 3.76μm versus 3.00μm for the GH6) due to its larger sensor. However, the GH6 is a somewhat more recent model (by 1 year) than the GFX 100S, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The resolution advantage of the Fujifilm GFX 100S implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GFX 100S for good quality output (200 dots per inch) amounts to 58.2 x 43.7 inches or 147.9 x 110.9 cm, for very good quality (250 dpi) 46.6 x 34.9 inches or 118.3 x 88.8 cm, and for excellent quality (300 dpi) 38.8 x 29.1 inches or 98.6 x 74 cm. The corresponding values for the Panasonic GH6 are 28.9 x 21.7 inches or 73.4 x 55.1 cm for good quality, 23.1 x 17.3 inches or 58.7 x 44.1 cm for very good quality, and 19.3 x 14.5 inches or 48.9 x 36.7 cm for excellent quality prints.

The GFX 100S has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Both cameras have the capacity to capture high quality composite images by combining multiple shots after shifting the sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

The Fujifilm GFX 100S has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 50-102400. The corresponding ISO settings for the Panasonic Lumix DC-GH6 are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-25600.

In terms of underlying technology, the GFX 100S is build around a BSI-CMOS sensor, while the GH6 uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

GFX 100S versus GH6 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports").

One feature that is present on the GFX 100S, but is missing on the GH6 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The GH6 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the GFX 100S does not have a selfie-screen.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, both cameras under consideration feature an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Fujifilm GFX 100S and the Panasonic GH6 both have an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

The GFX 100S writes its imaging data to SDXC cards, while the GH6 uses CFexpress (type B) or SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails. Moreover, both the GFX 100S and the GH6 support UHS-II cards, which provide for Ultra High Speed data transfer of up to 312 MB/s, on both slots.

Review summary

So what is the bottom line? Is the Fujifilm GFX 100S better than the Panasonic GH6 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Reasons to prefer the Fujifilm GFX 100S:

  • More detail: Offers more megapixels (101.8 vs 25MP) with a 102% higher linear resolution.
  • Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
  • Richer colors: The pixel size advantage translates into images with better, more accurate colors.
  • More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
  • Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.77x vs 0.76x).
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (2360k vs 1840k dots).
  • Longer lasting: Can take more shots (460 versus 360) on a single battery charge.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • More heavily discounted: Has been on the market for longer (launched in January 2021).

ilogo

Arguments in favor of the Panasonic Lumix DC-GH6:

  • Better video: Provides higher definition movie capture (5.7K/60p vs 4K/30p).
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (14 vs 5 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (138x100mm vs 150x104mm) and will fit more readily into a bag.
  • More solid recording: Has a full-sized HDMI port for a sturdy connection to an external recorder.
  • More affordable: Was introduced into a lower priced category (63 percent cheaper at launch).
  • More modern: Was introduced somewhat (1 year) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the GFX 100S is the clear winner of the match-up (13 : 8 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. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

GFX 100S 13:08 GH6

How about other alternatives? Do the specifications of the Fujifilm GFX 100S and the Panasonic GH6 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the GFX 100S and the GH6 in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
