Fujifilm GFX 100S vs Olympus E-M10 II
The Fujifilm GFX 100S and the Olympus OM-D E-M10 Mark II are two digital cameras that were officially introduced, respectively, in January 2021 and August 2015. Both the GFX 100S and the E-M10 II are mirrorless interchangeable lens cameras that are based on a medium format (GFX 100S) and a Four Thirds (E-M10 II) sensor. The Fujifilm has a resolution of 101.8 megapixels, whereas the Olympus provides 15.9 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm GFX 100S and the Olympus OM-D E-M10 Mark II? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
An illustration of the physical size and weight of the Fujifilm GFX 100S and the Olympus E-M10 II is provided 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.
The E-M10 II can be obtained in three different colors (black, silver, brown), while the GFX 100S is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-M10 II is considerably smaller (36 percent) than the Fujifilm GFX 100S. Moreover, the E-M10 II is substantially lighter (57 percent) than the GFX 100S. It is worth mentioning in this context that the GFX 100S is splash and dust resistant, while the E-M10 II 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 100S gets 460 shots out of its NP-W235 battery, while the E-M10 II can take 320 images on a single charge of its BLS-50 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 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 E-M10 II was launched at a markedly lower price (by 89 percent) than the GFX 100S, 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.
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. 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 100S features a medium format sensor and the Olympus E-M10 II a Four Thirds sensor. The sensor area in the E-M10 II 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.
With 101.8MP, the GFX 100S offers a higher resolution than the E-M10 II (15.9MP), but the GFX 100S nevertheless has the same individual pixel size (pixel pitch of 3.76μm) as the E-M10 II due to its larger sensor. It is noteworthy in this context that the GFX 100S is a mch more recent model (by 5 years and 5 months) than the E-M10 II, and its sensor will 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 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 Olympus E-M10 II are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 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.
Unlike the E-M10 II, the GFX 100S has the capacity to capture high quality composite images (YESMP) by combining multiple shots after shifting its 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 Olympus OM-D E-M10 Mark II are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
In terms of underlying technology, the GFX 100S is build around a BSI-CMOS sensor, while the E-M10 II 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.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the GFX 100S provides a higher video resolution than the E-M10 II. It can shoot video footage at 4K/30p, while the Olympus is limited to 1080/60p.
Apart from body and sensor, cameras can and do differ across a range of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the GFX 100S offers a substantially higher resolution than the one in the E-M10 II (3690k vs 2360k dots). The table below summarizes some of the other core capabilities of the Fujifilm GFX 100S and Olympus E-M10 II in connection with corresponding information for a sample of similar cameras.

|Notes: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.|
One feature that is present on the GFX 100S, but is missing on the E-M10 II 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 100S and the Olympus E-M10 II 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 100S and the E-M10 II write their files to SDXC cards. The GFX 100S features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-M10 II only has one slot. The GFX 100S supports UHS-II cards (on both slots), while the E-M10 II can use UHS-I cards.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Fujifilm GFX 100S and Olympus OM-D E-M10 Mark II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GFX 100S has a microphone port, which is missing on the E-M10 II. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Studio photographers will appreciate that the Fujifilm GFX 100S (unlike the E-M10 II) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The GFX 100S is a recent model that features in the current product line-up of Fujifilm. In contrast, the E-M10 II has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the E-M10 II was succeeded by the Olympus E-M10 III. Further information on the features and operation of the GFX 100S and E-M10 II can be found, respectively, in the Fujifilm GFX 100S Manual (free pdf) or the online Olympus E-M10 II Manual.
So what conclusions can be drawn? Which of the two cameras – the Fujifilm GFX 100S or the Olympus E-M10 II – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

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 (25 : 6 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Fujifilm GFX 100S and the Olympus E-M10 II 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the GFX 100S or the E-M10 II. 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 where reviews by experts come in. 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.

|Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.|
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. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
