Fujifilm X-T4 vs Olympus E-M5 III

The Fujifilm X-T4 and the Olympus OM-D E-M5 Mark III are two enthusiast cameras that were revealed to the public, respectively, in February 2020 and October 2019. Both the X-T4 and the E-M5 III are mirrorless interchangeable lens cameras that are based on an APS-C (X-T4) and a Four Thirds (E-M5 III) 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.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Fujifilm X-T4 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 width, height and depth measures are rounded to the nearest millimeter.

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

Size Fujifilm X-T4 vs Olympus E-M5 III
Compare X-T4 versus E-M5 III top
Comparison X-T4 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 (15 percent) than the Fujifilm X-T4. Moreover, the E-M5 III is markedly lighter (32 percent) than the X-T4. 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-T4) 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-T4 gets 500 shots out of its Fujifilm NP-W235 battery, while the E-M5 III can take 310 images on a single charge of its Olympus BLS-50 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. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

The price is, of course, an important factor in any camera decision. 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 E-M5 III was launched at a markedly lower price (by 29 percent) than the X-T4, 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.

Sensor comparison

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 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Fujifilm X-T4 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-T4 has a native 3:2 aspect ratio, while the one in the E-M5 III offers a 4:3 aspect.

Fujifilm X-T4 and Olympus E-M5 III sensor measures

With 26MP, the X-T4 offers a higher resolution than the E-M5 III (20.2MP), but the X-T4 nevertheless has larger individual pixels (pixel pitch of 3.76μm versus 3.34μm for the E-M5 III) due to its larger sensor. Moreover, the X-T4 is a somewhat more recent model (by 4 months) than the E-M5 III, and its sensor might 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 X-T4 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X-T4 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-M5 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.

Unlike the X-T4, 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-T4 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.

In terms of underlying technology, the X-T4 is build around a BSI-CMOS sensor, while the E-M5 III uses a CMOS imager. The X-T4 uses Fujifilm's X-Trans layout of photosites, while the E-M5 III employs the more common Bayer array.

Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.

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-T4 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-T4 and the E-M5 III write their files to SDXC cards. The X-T4 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.

Studio photographers will appreciate that the Fujifilm X-T4 (unlike the E-M5 III) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the X-T4 and the E-M5 III have been discontinued, but can regularly be found used on ebay. The E-M5 III was replaced by the OM System OM-5, while the X-T4 was followed by the Fujifilm X-T5. Further information on the features and operation of the X-T4 and E-M5 III can be found, respectively, in the Fujifilm X-T4 Manual (free pdf) or the online Olympus E-M5 III Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Fujifilm X-T4 or the Olympus E-M5 III – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

ilogo

Advantages of the Fujifilm X-T4:

  • 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).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.75x vs 0.68x).
  • More detailed LCD: Has a higher resolution rear screen (1620k vs 1040k dots).
  • Faster burst: Shoots at higher frequency (15 vs 10 flaps/sec) to capture the decisive moment.
  • Longer lasting: Can take more shots (500 versus 310) on a single battery charge.
  • Faster data transfer: Supports a more advanced USB protocol (3.1 vs 2.0).
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More modern: Is somewhat more recent (announced 4 months after the E-M5 III).

ilogo

Reasons to prefer the Olympus OM-D E-M5 Mark III:

  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • More compact: Is smaller (125x85mm vs 135x93mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 193g or 32 percent) and is thus easier to take along.
  • More affordable: Was introduced into a lower priced category (29 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in October 2019).

If the number of relative strengths (bullet points above) is taken as a guide, the X-T4 is the clear winner of the match-up (15 : 5 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 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.

X-T4 15:05 E-M5 III

How about other alternatives? Do the specifications of the Fujifilm X-T4 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the X-T4 and the E-M5 III in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

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.

padding

The above review scores should be interpreted 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 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.
