Fujifilm X-M1 vs Olympus E-520
The Fujifilm X-M1 and the Olympus E-520 are two digital cameras that were announced, respectively, in June 2013 and May 2008. The X-M1 is a mirrorless interchangeable lens camera, while the E-520 is a DSLR. The cameras are based on an APS-C (X-M1) and a Four Thirds (E-520) sensor. The Fujifilm has a resolution of 16 megapixels, whereas the Olympus provides 10 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 E-520? 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.
An illustration of the physical size and weight of the Fujifilm X-M1 and the Olympus E-520 is provided 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 width, height and depth dimensions are rounded to the nearest millimeter.
The X-M1 can be obtained in three different colors (black, silver, brown), while the E-520 is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-520 is considerably larger (60 percent) than the Fujifilm X-M1. Moreover, the E-520 is substantially heavier (62 percent) than the X-M1. In this context, it is worth noting that neither the X-M1 nor the E-520 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 Four Thirds Lens Catalog (E-520). Mirrorless cameras, such as the Fujifilm X-M1, have moreover the advantage that they have a relatively short flange to focal plane distance and can thus use many lenses from other systems via adapters.
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. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Any camera decision will obviously take relative prices into account. 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 two cameras under review were launched at the same price and fall into the same 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 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-520 a Four Thirds sensor. The sensor area in the E-520 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-520 offers a 4:3 aspect.
With 16MP, the X-M1 offers a higher resolution than the E-520 (10MP), but the X-M1 nevertheless has marginally larger individual pixels (pixel pitch of 4.80μm versus 4.74μm for the E-520) due to its larger sensor. Moreover, the X-M1 is a much more recent model (by 5 years and 1 month) than the E-520, 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 inch or 62.2 x 41.5 cm, for very good quality (250 dpi) 19.6 x 13.1 inch or 49.7 x 33.2 cm, and for excellent quality (300 dpi) 16.3 x 10.9 inch or 41.5 x 27.6 cm. The corresponding values for the Olympus E-520 are 18.2 x 13.7 inch or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inch or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inch or 30.9 x 23.2 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 E-520 are ISO 100 to ISO 1600 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. 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 cannot only take still pictures, but also record videos. The X-M1 indeed provides movie recording capabilities, while the E-520 does not. The highest resolution format that the X-M1 can use is 1080/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the E-520 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the X-M1 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Fujifilm X-M1, the Olympus E-520, and comparable cameras.

One feature that differentiates the E-520 and the X-M1 is in-body image stabilization (IBIS). The E-520 reduces the risk of handshake-induced blur with all attached lenses, while the X-M1 has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.
The X-M1 writes its imaging data to SDXC cards, while the E-520 uses Compact Flash or xD Picture cards. The E-520 features dual card slots, which can be very useful in case a memory card fails. In contrast, the X-M1 only has one slot.
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 E-520 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-520 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-520 have been discontinued, but can regularly be found used on eBay. Neither of the two has a direct successor, so they represent the end of the respective camera lines from Fujifilm and 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 what conclusions can be drawn? Which of the two cameras – the Fujifilm X-M1 or the Olympus E-520 – has the upper hand? Is one clearly better than the other? 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 10MP) with a 29% 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.
- Broader imaging potential: Can record not only still images but also 1080/30p movies.
- Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (920k vs 215k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Faster burst: Shoots at higher frequency (5.6 vs 3.5 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (117x67mm vs 136x92mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 205g or 38 percent) and hence easier to carry around.
- More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- More modern: Reflects 5 years and 1 month of technical progress since the E-520 launch.
Reasons to prefer the Olympus E-520:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Easier framing: Has an optical viewfinder for image composition and settings control.
- Longer lasting: Gets more shots (750 versus 350) out of a single battery charge.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- More heavily discounted: Has been around for much longer (launched in May 2008).
If the number of relative strengths (bullet points above) is taken as a guide, the X-M1 is the clear winner of the match-up (16 : 6 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 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-520 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR Camera listings 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-M1 and the E-520 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 expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.
The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
