Fujifilm GFX 100 vs X-T20

The Fujifilm GFX 100 and the Fujifilm X-T20 are two digital cameras that were revealed to the public, respectively, in May 2019 and January 2017. Both the GFX 100 and the X-T20 are mirrorless interchangeable lens cameras that are based on a medium format (GFX 100) and an APS-C (X-T20) sensor. The GFX 100 has a resolution of 101.8 megapixels, whereas the X-T20 provides 24 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Body comparison

An illustration of the physical size and weight of the Fujifilm GFX 100 and the Fujifilm X-T20 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 size dimensions are rounded to the nearest millimeter.

The X-T20 can be obtained in two different colors (black, silver), while the GFX 100 is only available in black.

Compare GFX 100 versus X-T20 top
Comparison GFX 100 or X-T20 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Fujifilm X-T20 is considerably smaller (56 percent) than the Fujifilm GFX 100. Moreover, the X-T20 is substantially lighter (71 percent) than the GFX 100. It is worth mentioning in this context that the GFX 100 is splash and dust resistant, 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. 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 100 gets 800 shots out of its Fujifilm NP-T125 battery, while the X-T20 can take 350 images on a single charge of its Fujifilm NP-W126S power pack. As can be seen in the images above, the GFX 100 has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

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 X-T20 was launched at a markedly lower price (by 91 percent) than the GFX 100, 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Fujifilm GFX 100 features a medium format sensor and the Fujifilm X-T20 an APS-C sensor. The sensor area in the X-T20 is 74 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 0.79 and 1.5. The sensor in the GFX 100 has a native 4:3 aspect ratio, while the one in the X-T20 offers a 3:2 aspect.

Fujifilm GFX 100 and Fujifilm X-T20 sensor measures

With 101.8MP, the GFX 100 offers a higher resolution than the X-T20 (24MP), but the GFX 100 has smaller individual pixels (pixel pitch of 3.76μm versus 3.92μm for the X-T20). However, the GFX 100 is a much more recent model (by 2 years and 4 months) than the X-T20, and its sensor will 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 100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GFX 100 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 Fujifilm X-T20 are 30 x 20 inches or 76.2 x 50.8 cm for good quality, 24 x 16 inches or 61 x 40.6 cm for very good quality, and 20 x 13.3 inches or 50.8 x 33.9 cm for excellent quality prints.

The Fujifilm GFX 100 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 Fujifilm X-T20 are ISO 200 to ISO 12800, with the possibility to increase the ISO range to 100-51200.

In terms of underlying technology, the GFX 100 is build around a BSI-CMOS sensor, while the X-T20 uses a CMOS imager. Like most digital cameras, the GFX 100 uses a Bayer filter for capturing RGB colors on a square grid of photosensors. In contrast, the X-T20 employs a more randomized X-Trans layout of photosites, which according to Fujifilm helps to minimize moiré.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the X-T20 has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GFX 100 relies on live view and the rear LCD for framing. That said, the GFX 100 can be equipped with an optional viewfinder – the EVF-GFX2. The table below summarizes some of the other core capabilities of the Fujifilm GFX 100 and Fujifilm X-T20 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the GFX 100, but is missing on the X-T20 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 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 100 and the Fujifilm X-T20 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.

Concerning the storage of imaging data, both the GFX 100 and the X-T20 write their files to SDXC cards. The GFX 100 features dual card slots, which can be very useful in case a memory card fails. In contrast, the X-T20 only has one slot. The GFX 100 supports UHS-II cards (on both slots), while the X-T20 can use UHS-I cards.

It is notable that the GFX 100 has a headphone jack, which is not present on the X-T20 This port makes it possible to attach external headphones and monitor the quality of sound during the recording process.

Studio photographers will appreciate that the Fujifilm GFX 100 (unlike the X-T20) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the GFX 100 and the X-T20 have been discontinued, but can regularly be found used on ebay. The X-T20 was replaced by the Fujifilm X-T100, while the GFX 100 was followed by the Fujifilm GFX 100 II. Further information on the features and operation of the GFX 100 and X-T20 can be found, respectively, in the Fujifilm GFX 100 Manual (free pdf) or the online Fujifilm X-T20 Manual.

Advantages of the Fujifilm X-T20:

  • Easier framing: Has an electronic viewfinder for image composition and settings control.
  • Faster burst: Shoots at higher frequency (8 vs 5 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (118x83mm vs 156x144mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 937g or 71 percent) and is thus easier to take along.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (91 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in January 2017).

If the number of relative strengths (bullet points above) is taken as a guide, the GFX 100 is the clear winner of the match-up (20 : 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. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

GFX 100 20:07 X-T20

How about other alternatives? Do the specifications of the Fujifilm GFX 100 and the Fujifilm X-T20 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the GFX 100 and the X-T20 in practical situations. 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.

Expert reviews

This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera 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.

padding

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
