Fujifilm X-T1 vs Olympus E-PM1
The Fujifilm X-T1 and the Olympus PEN E-PM1 are two digital cameras that were announced, respectively, in January 2014 and June 2011. Both the X-T1 and the E-PM1 are mirrorless interchangeable lens cameras that are based on an APS-C (X-T1) and a Four Thirds (E-PM1) sensor. The Fujifilm has a resolution of 16 megapixels, whereas the Olympus provides 12.2 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-T1 and the Olympus PEN E-PM1? 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-T1 and the Olympus E-PM1. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.
The X-T1 can be obtained in two different colors (black, silver), while the E-PM1 is available in six color-versions (black, silver, brown, pink, purple, white).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-PM1 is considerably smaller (39 percent) than the Fujifilm X-T1. Moreover, the E-PM1 is substantially lighter (40 percent) than the X-T1. It is worth mentioning in this context that the X-T1 is splash and dust resistant, while the E-PM1 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-T1) and the Micro Four Thirds Lens Catalog (E-PM1). 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.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 E-PM1 was launched at a markedly lower price (by 62 percent) than the X-T1, which puts it into a different market segment. 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.
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 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-T1 features an APS-C sensor and the Olympus E-PM1 a Four Thirds sensor. The sensor area in the E-PM1 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-T1 has a native 3:2 aspect ratio, while the one in the E-PM1 offers a 4:3 aspect.
With 16MP, the X-T1 offers a higher resolution than the E-PM1 (12.2MP), but the X-T1 nevertheless has larger individual pixels (pixel pitch of 4.80μm versus 4.29μm for the E-PM1) due to its larger sensor. Moreover, the X-T1 is a much more recent model (by 2 years and 7 months) than the E-PM1, 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-T1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Fujifilm X-T1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X-T1 for good quality output (200 dots per inch) amounts to 24.5 x 16.3 inches or 62.2 x 41.5 cm, for very good quality (250 dpi) 19.6 x 13.1 inches or 49.7 x 33.2 cm, and for excellent quality (300 dpi) 16.3 x 10.9 inches or 41.5 x 27.6 cm. The corresponding values for the Olympus E-PM1 are 20.2 x 15.1 inches or 51.2 x 38.4 cm for good quality, 16.1 x 12.1 inches or 41 x 30.7 cm for very good quality, and 13.4 x 10.1 inches or 34.1 x 25.6 cm for excellent quality prints.
The X-T1 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Fujifilm X-T1 has a native sensitivity range from ISO 200 to ISO 6400, which can be extended to ISO 100-51200. The corresponding ISO settings for the Olympus PEN E-PM1 are ISO 100 to ISO 12800 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the X-T1 provides a higher frame rate than the E-PM1. It can shoot video footage at 1080/60p, while the Olympus is limited to 1080/60i.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the X-T1 has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the E-PM1 relies on live view and the rear LCD for framing. That said, the E-PM1 can be equipped with an optional viewfinder – the VF-2. The table below summarizes some of the other core capabilities of the Fujifilm X-T1 and Olympus E-PM1 in connection with corresponding information for a sample of similar cameras.
One feature that differentiates the E-PM1 and the X-T1 is in-body image stabilization (IBIS). The E-PM1 reduces the risk of handshake-induced blur with all attached lenses, while the X-T1 offers no blur reduction with lenses that themselves do not provide optical image stabilization.
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-T1 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-T1 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-T1 and the E-PM1 write their files to SDXC cards. The X-T1 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the E-PM1 cannot take advantage of Ultra High Speed SD 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-T1 and Olympus PEN E-PM1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the X-T1 has a microphone port, which is missing on the E-PM1. 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-T1 (unlike the E-PM1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the X-T1 and the E-PM1 have been discontinued, but can regularly be found used on eBay. The E-PM1 was replaced by the Olympus E-PM2, while the X-T1 was followed by the Fujifilm X-T2. 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 what is the bottom line? Is there a clear favorite between the Fujifilm X-T1 and the Olympus E-PM1? Which camera is better? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Fujifilm X-T1:

If the number of relative strengths (bullet points above) is taken as a guide, the X-T1 is the clear winner of the match-up (20 : 6 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 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.
How about other alternatives? Do the specifications of the Fujifilm X-T1 and the Olympus E-PM1 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-T1 and the E-PM1 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 table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 assessments were made in relation to similar cameras of the same technological generation. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
