Body comparison

The physical size and weight of the Fujifilm X100S and the Olympus E-M1 III are illustrated 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.

The X100S can be obtained in two different colors (black, silver), while the E-M1 III is only available in black.

Compare X100S versus E-M1 III top
Comparison X100S 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 larger (30 percent) than the Fujifilm X100S. It is noteworthy in this context that the E-M1 III is splash and dust-proof, while the X100S does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the X100S has a lens built in, whereas the E-M1 III is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the E-M1 III and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the X100S gets 330 shots out of its Fujifilm NP-95 battery, while the E-M1 III can take 420 images on a single charge of its Olympus BLH-1 power pack. The power pack in the E-M1 III can be charged via the USB port, which can be very convenient when travelling.

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

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 X100S was launched at a lower price than the E-M1 III, despite having a lens built in. 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. 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 X100S features an APS-C sensor and the Olympus E-M1 III a Four Thirds sensor. The sensor area in the E-M1 III 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 X100S has a native 3:2 aspect ratio, while the one in the E-M1 III offers a 4:3 aspect.

Fujifilm X100S and Olympus E-M1 III sensor measures

Despite having a smaller sensor, the E-M1 III offers a higher resolution of 20.2 megapixels, compared with 16 MP of the X100S. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.34μm versus 4.80μm for the X100S). However, it should be noted that the E-M1 III is much more recent (by 7 years and 1 month) than the X100S, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. 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 Olympus E-M1 III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-M1 III for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm. The corresponding values for the Fujifilm X100S are 24.5 x 16.3 inches or 62.2 x 41.5 cm for good quality, 19.6 x 13.1 inches or 49.7 x 33.2 cm for very good quality, and 16.3 x 10.9 inches or 41.5 x 27.6 cm for excellent quality prints.

Unlike the X100S, the E-M1 III has the capacity to capture high quality composite images (80MP) 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 X100S has a native sensitivity range from ISO 200 to ISO 6400, which can be extended to ISO 100-25600. 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.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. The X100S uses Fujifilm's X-Trans layout of photosites, while the E-M1 III employs the more common Bayer array.

X100S versus E-M1 III MP

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

One difference between the cameras concerns the presence of an on-board flash. The X100S has one, while the E-M1 III does not. While the built-in flash of the X100S is not very powerful, it can at times be useful as a fill-in light.

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 X100S 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, the E-M1 III is one of those camera that have an additional 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 Olympus E-M1 III has 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 X100S and the E-M1 III write their files to SDXC cards. The E-M1 III features dual card slots, which can be very useful in case a memory card fails. In contrast, the X100S only has one slot. The E-M1 III supports UHS-II cards (on its first slot), while the X100S can use UHS-I cards.

It is notable that the E-M1 III offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the X100S does not provide wifi capability.

Studio photographers will appreciate that the Olympus E-M1 III (unlike the X100S) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the X100S and the E-M1 III have been discontinued, but can regularly be found used on ebay. The X100S was replaced by the Fujifilm X100T, while the E-M1 III was followed by the OM System OM-1. Further information on the features and operation of the X100S and E-M1 III can be found, respectively, in the Fujifilm X100S Manual (free pdf) or the online Olympus E-M1 III Manual.

  • Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
  • More modern: Reflects 7 years and 1 month of technical progress since the X100S launch.

If the count of relative strengths (bullet points above) is taken as a measure, the E-M1 III is the clear winner of the contest (27 : 6 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. 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.

X100S 06:27 E-M1 III

How about other alternatives? Do the specifications of the Fujifilm X100S and the Olympus E-M1 III place the cameras among the top in their class? Find out in the latest Best Prime Lens Compact Camera and Best Mirrorless Interchangeable Lens Camera listings 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 incomplete and does no justice, for example, to the way the X100S or the E-M1 III perform in practice. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Expert reviews

This is where reviews by experts come in. 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.

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

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
