Body comparison

An illustration of the physical size and weight of the Fujifilm GFX 100S II and the Olympus E-M1 III is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.

Compare GFX 100S II versus E-M1 III top
Comparison GFX 100S II or E-M1 III rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-M1 III is notably smaller (22 percent) than the Fujifilm GFX 100S II. Moreover, the E-M1 III is markedly lighter (34 percent) than the GFX 100S II. 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 II gets 530 shots out of its Fujifilm NP-W235 battery, while the E-M1 III can take 420 images on a single charge of its Olympus BLH-1 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

Any camera decision 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 E-M1 III was launched at a markedly lower price (by 64 percent) than the GFX 100S II, 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 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Fujifilm GFX 100S II features a medium format sensor and the Olympus E-M1 III a Four Thirds sensor. The sensor area in the E-M1 III 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 II and Olympus E-M1 III sensor measures

With 101.8MP, the GFX 100S II offers a higher resolution than the E-M1 III (20.2MP), but the GFX 100S II nevertheless has larger individual pixels (pixel pitch of 3.76μm versus 3.34μm for the E-M1 III) due to its larger sensor. Moreover, the GFX 100S II is a much more recent model (by 4 years and 3 months) than the E-M1 III, 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 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GFX 100S II 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-M1 III are 25.9 x 19.4 inches or 65.8 x 49.4 cm for good quality, 20.7 x 15.6 inches or 52.7 x 39.5 cm for very good quality, and 17.3 x 13 inches or 43.9 x 32.9 cm for excellent quality prints.

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 II 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-M1 Mark III are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 64-25600.

In terms of underlying technology, the GFX 100S II is build around a BSI-CMOS sensor, while the E-M1 III 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.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One feature that is present on the GFX 100S II, but is missing on the E-M1 III 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 E-M1 III 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 II 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 II and the Olympus E-M1 III 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 II and the E-M1 III write their files to SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails. However, while the GFX 100S II supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s) on both slots, the E-M1 III supports UHS-II only on its first slot and UHS-I (data transfer speed up to 104 MB/s) on the second one.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.

The GFX 100S II is a recent model that features in the current product line-up of Fujifilm. In contrast, the E-M1 III has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the E-M1 III was succeeded by the OM System OM-1. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Fujifilm and Olympus websites.

ilogo

Reasons to prefer the Olympus OM-D E-M1 Mark III:

  • 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 (18 vs 7 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (134x91mm vs 150x104mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 303g or 34 percent) and is thus easier to take along.
  • More affordable: Was introduced into a lower priced category (64 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in February 2020).

If the count of individual advantages (bullet points above) is taken as a guide, the GFX 100S II is the clear winner of the match-up (13 : 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 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.

How about other alternatives? Do the specifications of the Fujifilm GFX 100S II and the Olympus E-M1 III 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 100S II and the E-M1 III 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 hands-on reviews by experts 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

Care should be taken when interpreting the review scores above, 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
