Fujifilm X-T3 vs Olympus E-M1X
The Fujifilm X-T3 and the Olympus OM-D E-M1X are two enthusiast cameras that were officially introduced, respectively, in September 2018 and January 2019. Both the X-T3 and the E-M1X are mirrorless interchangeable lens cameras that are based on an APS-C (X-T3) and a Four Thirds (E-M1X) sensor. The Fujifilm has a resolution of 26 megapixels, whereas the Olympus provides 20.2 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 X-T3 and the Olympus OM-D E-M1X? 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.
The physical size and weight of the Fujifilm X-T3 and the Olympus E-M1X are illustrated 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 width, height and depth dimensions are rounded to the nearest millimeter.
Both cameras are available in two different colors (black, silver).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-M1X is considerably larger (71 percent) than the Fujifilm X-T3. Moreover, the E-M1X is substantially heavier (85 percent) than the X-T3. 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Fujinon X Lens Catalog (X-T3) and the Micro Four Thirds Lens Catalog (E-M1X). Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.
Concerning battery life, the X-T3 gets 390 shots out of its NP-W126S battery, while the E-M1X can take 870 images on a single charge of its BLH-1 power pack. As can be seen in the images above, the E-M1X has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. In order to provide similar functionality for the X-T3, Fujifilm provides the VG-XT3 vertical grip as an optional accessory (see here on eBay). The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The X-T3 was launched at a markedly lower price (by 50 percent) than the E-M1X, 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.
The size of the sensor inside a digital camera is one of the key determinants 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. 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 X-T3 features an APS-C sensor and the Olympus E-M1X a Four Thirds sensor. The sensor area in the E-M1X 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 X-T3 has a native 3:2 aspect ratio, while the one in the E-M1X offers a 4:3 aspect.
With 26MP, the X-T3 offers a higher resolution than the E-M1X (20.2MP), but the X-T3 nevertheless has larger individual pixels (pixel pitch of 3.76μm versus 3.34μm for the E-M1X) due to its larger sensor. However, the E-M1X is a somewhat more recent model (by 4 months) than the X-T3, 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 X-T3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X-T3 for good quality output (200 dots per inch) amounts to 31.2 x 20.8 inches or 79.2 x 52.8 cm, for very good quality (250 dpi) 25 x 16.6 inches or 63.4 x 42.3 cm, and for excellent quality (300 dpi) 20.8 x 13.9 inches or 52.8 x 35.2 cm. The corresponding values for the Olympus E-M1X 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.
Unlike the X-T3, the E-M1X 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 X-T3 has a native sensitivity range from ISO 160 to ISO 12800, which can be extended to ISO 80-51200. The corresponding ISO settings for the Olympus OM-D E-M1X are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 64-25600.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. 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 can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the X-T3 provides a higher frame rate than the E-M1X. It can shoot video footage at 4K/60p, while the Olympus is limited to 4K/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the X-T3 offers a substantially higher resolution than the one in the E-M1X (3690k vs 2360k dots). The following table reports on some other key feature differences and similarities of the Fujifilm X-T3, the Olympus E-M1X, and comparable cameras.
|Canon G1 X Mark III||2360||n||3.0||1040||swivel||Y||1/2000s||9.0||Y||Y|
|Olympus E-M1 III||2360||n||3.0||1037||swivel||Y||1/8000s||18.0||n||Y|

One feature that differentiates the E-M1X and the X-T3 is in-body image stabilization (IBIS). The E-M1X reduces the risk of handshake-induced blur with all attached lenses, while the X-T3 offers no blur reduction with lenses that themselves do not provide optical image stabilization.The E-M1X 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 X-T3 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 X-T3 and the Olympus E-M1X 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 X-T3 and the E-M1X write their files to SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails. Moreover, both the X-T3 and the E-M1X support UHS-II cards, which provide for Ultra High Speed data transfer of up to 312 MB/s, on both slots.
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 X-T3 and Olympus OM-D E-M1X and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.
Travel and landscape photographers will find it useful that the E-M1X has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.
Both the X-T3 and the E-M1X are recent models that are part of the current product line-up. The X-T3 replaced the earlier Fujifilm X-T2, while the E-M1X does not have a direct predecessor. 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.
So how do things add up? Is the Fujifilm X-T3 better than the Olympus E-M1X or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Fujifilm X-T3:
- More detail: Offers more megapixels (26 vs 20.2MP) with a 16% 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 video: Provides higher movie framerates (4K/60p versus 4K/30p).
- More detailed viewfinder: Has higher resolution electronic viewfinder (3690k vs 2360k dots).
- More compact: Is smaller (133x93mm vs 144x147mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 458g or 46 percent) and hence easier to carry around.
- More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in September 2018).
Reasons to prefer the Olympus OM-D E-M1X:
- High quality composites: Can combine several shots after pixel-shifting its sensor.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.83x vs 0.75x).
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (18 vs 11 flaps/sec) to capture the decisive moment.
- More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
- Longer lasting: Gets more shots (870 versus 390) out of a single battery charge.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- Easier geotagging: Features an internal GPS sensor to log localization data.
- More modern: Was introduced somewhat (4 months) more recently.
If the count of relative strengths (bullet points above) is taken as a measure, the X-T3 comes out slightly ahead of the E-M1X (11 : 10 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 X-T3 and the Olympus E-M1X 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 X-T3 or the E-M1X. 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 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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 review scores listed above should be treated 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
