Fujifilm X-T4 vs Olympus E-PM2
The Fujifilm X-T4 and the Olympus PEN E-PM2 are two digital cameras that were announced, respectively, in February 2020 and September 2012. Both the X-T4 and the E-PM2 are mirrorless interchangeable lens cameras that are based on an APS-C (X-T4) and a Four Thirds (E-PM2) sensor. The Fujifilm has a resolution of 26 megapixels, whereas the Olympus provides 15.9 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-T4 and the Olympus PEN E-PM2? 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 side-by-side display below illustrates the physical size and weight of the Fujifilm X-T4 and the Olympus E-PM2. 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.
The X-T4 can be obtained in two different colors (black, silver), while the E-PM2 is available in four color-versions (black, silver, red, white).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-PM2 is considerably smaller (44 percent) than the Fujifilm X-T4. Moreover, the E-PM2 is substantially lighter (56 percent) than the X-T4. It is worth mentioning in this context that the X-T4 is splash and dust resistant, while the E-PM2 does not feature any corresponding weather-sealing.
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-PM2). 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 NP-W235 battery, while the E-PM2 can take 360 images on a single charge of its BLS-5 power pack. The power pack in the X-T4 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-PM2 was launched at a markedly lower price (by 71 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The size of the sensor inside a digital camera is one of the key determinants 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 more expensive and 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-PM2 a Four Thirds sensor. The sensor area in the E-PM2 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-PM2 offers a 4:3 aspect.
With 26MP, the X-T4 offers a higher resolution than the E-PM2 (15.9MP), but the X-T4 nevertheless has the same individual pixel size (pixel pitch of 3.76μm) as the E-PM2 due to its larger sensor. It is noteworthy in this context that the X-T4 is a mch more recent model (by 7 years and 5 months) than the E-PM2, 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 the X-T4 has no anti-alias filter installed, so that it can capture all the detail its 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-PM2 are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 cm for excellent quality prints.
The X-T4 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
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 PEN E-PM2 are ISO 100 to ISO 25600 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). 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 also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the X-T4 provides a higher video resolution than the E-PM2. It can shoot video footage at 4K/60p, while the Olympus is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the X-T4 has an electronic viewfinder (3690k dots), which can be very helpful when shooting in bright sunlight. In contrast, the E-PM2 relies on live view and the rear LCD for framing. That said, the E-PM2 can be equipped with an optional viewfinder – the VF-4. The adjacent table lists some of the other core features of the Fujifilm X-T4 and Olympus E-PM2 along with similar information for a selection of comparators.

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 X-T4 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 Fujifilm X-T4 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 X-T4 and the E-PM2 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-PM2 only has one slot. The X-T4 supports UHS-II cards (on both slots), while the E-PM2 can use UHS-I cards.
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-T4 and Olympus PEN E-PM2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the X-T4 has a microphone port, which is missing on the E-PM2. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Studio photographers will appreciate that the Fujifilm X-T4 (unlike the E-PM2) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The X-T4 is a recent model that features in the current product line-up of Fujifilm. In contrast, the E-PM2 has been discontinued (but can be found pre-owned on eBay). There has not been a direct replacement model for the E-PM2 from Olympus. 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 there a clear favorite between the Fujifilm X-T4 and the Olympus E-PM2? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

- More heavily discounted: Has been around for much longer (launched in September 2012).
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 (27 : 5 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.

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-PM2 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.
This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], 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.

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. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
