Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm X-T3 and the Olympus OM-D E-M5 Mark III? 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.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Fujifilm X-T3 and the Olympus E-M5 III. 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.

Both cameras are available in two different colors (black, silver).

Compare X-T3 versus E-M5 III top
Comparison X-T3 or E-M5 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-M5 III is notably smaller (14 percent) than the Fujifilm X-T3. Moreover, the E-M5 III is markedly lighter (23 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-M5 III). 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-M5 III can take 310 images on a single charge of its BLS-50 power pack. 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 want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table.

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

The price is, of course, an important factor in any camera decision. 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-M5 III was launched at a somewhat lower price (by 20 percent) than the X-T3, which makes it more attractive for photographers on a tight budget. 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. 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 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. 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 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-M5 III a Four Thirds sensor. The sensor area in the E-M5 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 X-T3 has a native 3:2 aspect ratio, while the one in the E-M5 III offers a 4:3 aspect.

Fujifilm X-T3 and Olympus E-M5 III sensor measures

With 26MP, the X-T3 offers a higher resolution than the E-M5 III (20.2MP), but the X-T3 nevertheless has larger individual pixels (pixel pitch of 3.76μm versus 3.34μm for the E-M5 III) due to its larger sensor. However, the E-M5 III is a somewhat more recent model (by 1 year and 1 month) 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 inch or 79.2 x 52.8 cm, for very good quality (250 dpi) 25 x 16.6 inch or 63.4 x 42.3 cm, and for excellent quality (300 dpi) 20.8 x 13.9 inch or 52.8 x 35.2 cm. The corresponding values for the Olympus E-M5 III are 25.9 x 19.4 inch or 65.8 x 49.4 cm for good quality, 20.7 x 15.6 inch or 52.7 x 39.5 cm for very good quality, and 17.3 x 13 inch or 43.9 x 32.9 cm for excellent quality prints.

Unlike the X-T3, the E-M5 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 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-M5 Mark III are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 64-25600.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the X-T3 provides a higher frame rate than the E-M5 III. It can shoot video footage at 4K/60p, while the Olympus is limited to 4k/24p.

 

Feature comparison

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 X-T3 offers a substantially higher resolution than the one in the E-M5 III (3690k vs 2360k dots).

One feature that differentiates the E-M5 III and the X-T3 is in-body image stabilization (IBIS). The E-M5 III reduces the risk of handshake-induced blur with all attached lenses, while the X-T3 has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

The E-M5 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 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-M5 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 X-T3 and the E-M5 III write their files to SDXC cards. The X-T3 features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-M5 III only has one slot. Both cameras support UHS-II cards, which provide for Ultra High Speed data transfer of up to 312 MB/s.

 

Connectivity comparison

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-M5 Mark III and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the X-T3 has a headphone jack, which is not present on the E-M5 III This port makes it possible to attach external headphones and monitor the quality of sound during the recording process.

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

Both the X-T3 and the E-M5 III are recent models that are part of the current product line-up. The X-T3 replaced the earlier Fujifilm X-T2, while the E-M5 III followed on from the Olympus E-M5 II. 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.

Review summary

So what is the bottom line? Which of the two cameras – the Fujifilm X-T3 or the Olympus E-M5 III – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

ilogo

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/24p).
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (3690k vs 2360k dots).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.75x vs 0.68x).
  • Longer lasting: Can take more shots (390 versus 310) on a single battery charge.
  • Faster data transfer: Supports a more advanced USB protocol (3.1 vs 2.0).
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More heavily discounted: Has been on the market for longer (launched in September 2018).

ilogo

Advantages of the Olympus OM-D E-M5 Mark III:

  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • 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.
  • More compact: Is smaller (125x85mm vs 133x93mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 125g or 23 percent) and is thus easier to take along.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • More affordable: Was released into a lower priced segment (20 percent cheaper at launch).
  • More modern: Was introduced somewhat (1 year and 1 month) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the X-T3 is the clear winner of the match-up (13 : 8 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 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.

X-T3 13:08 E-M5 III

How about other alternatives? Do the specifications of the Fujifilm X-T3 and the Olympus E-M5 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the X-T3 and the E-M5 III in practical situations. 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 following table reports the overall ratings of the cameras as published by some of the major camera 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.

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

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
