Fujifilm X-M1 vs Olympus E-P1
The Fujifilm X-M1 and the Olympus PEN E-P1 are two digital cameras that were revealed to the public, respectively, in June 2013 and June 2009. Both the X-M1 and the E-P1 are mirrorless interchangeable lens cameras that are based on an APS-C (X-M1) and a Four Thirds (E-P1) 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-M1 and the Olympus PEN E-P1? 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-M1 and the Olympus E-P1 are illustrated in the side-by-side display below. 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-M1 can be obtained in three different colors (black, silver, brown), while the E-P1 is also available in three color-versions, but different ones (black, silver, white).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-P1 is notably larger (8 percent) than the Fujifilm X-M1. Moreover, the E-P1 is markedly heavier (8 percent) than the X-M1. In this context, it is worth noting that neither the X-M1 nor the E-P1 are weather-sealed.
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-M1) and the Micro Four Thirds Lens Catalog (E-P1). 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 adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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.

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 X-M1 was launched at a somewhat lower price (by 13 percent) than the E-P1, 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.
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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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-M1 features an APS-C sensor and the Olympus E-P1 a Four Thirds sensor. The sensor area in the E-P1 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-M1 has a native 3:2 aspect ratio, while the one in the E-P1 offers a 4:3 aspect.
With 16MP, the X-M1 offers a higher resolution than the E-P1 (12.2MP), but the X-M1 nevertheless has larger individual pixels (pixel pitch of 4.80μm versus 4.29μm for the E-P1) due to its larger sensor. Moreover, the X-M1 is a much more recent model (by 4 years) than the E-P1, 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-M1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Fujifilm X-M1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X-M1 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-P1 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 Fujifilm X-M1 has a native sensitivity range from ISO 200 to ISO 6400, which can be extended to ISO 100-25600. The corresponding ISO settings for the Olympus PEN E-P1 are ISO 100 to ISO 6400 (no boost).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the X-M1 provides a higher video resolution than the E-P1. It can shoot video footage at 1080/30p, while the Olympus is limited to 720/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. The X-M1 and the E-P1 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. The adjacent table lists some of the other core features of the Fujifilm X-M1 and Olympus E-P1 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The X-M1 has one, while the E-P1 does not. While the built-in flash of the X-M1 is not very powerful, it can at times be useful as a fill-in light.
The X-M1 writes its imaging data to SDXC cards, while the E-P1 uses SDHC cards. The X-M1 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the E-P1 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-M1 and Olympus PEN E-P1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the X-M1 offers wifi support, while the E-P1 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the X-M1 and the E-P1 have been discontinued, but can regularly be found used on eBay. The E-P1 was replaced by the Olympus E-P2, while the X-M1 does not have a direct successor. 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-M1 and the Olympus E-P1? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Fujifilm X-M1:
- More detail: Offers more megapixels (16 vs 12.2MP) with a 17% higher linear resolution.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Features a larger and more technologically advanced imaging sensor.
- Richer colors: The sensor size advantage translates into images with better, more accurate colors.
- More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
- Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
- Better video: Provides higher definition movie capture (1080/30p vs 720/30p).
- More detailed LCD: Has a higher resolution rear screen (920k vs 230k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Faster burst: Shoots at higher frequency (5.6 vs 3 flaps/sec) to capture the decisive moment.
- Longer lasting: Can take more shots (350 versus 300) on a single battery charge.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More affordable: Was introduced into a lower priced segment (13 percent cheaper at launch).
- More modern: Reflects 4 years of technical progress since the E-P1 launch.
Advantages of the Olympus PEN E-P1:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- More heavily discounted: Has been around for much longer (launched in June 2009).
If the count of individual advantages (bullet points above) is taken as a guide, the X-M1 is the clear winner of the match-up (16 : 3 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-M1 and the Olympus E-P1 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 incomplete and does no justice, for example, to the way the X-M1 or the E-P1 perform in practice. 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.
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], 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.

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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
