Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm X10 and the Olympus OM-D E-M10 Mark IV? 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.
Body comparison
The physical size and weight of the Fujifilm X10 and the Olympus E-M10 IV are illustrated in the side-by-side display below. 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.
Both cameras are available in two different colors (black, silver).



If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-M10 IV is notably larger (25 percent) than the Fujifilm X10. In this context, it is worth noting that neither the X10 nor the E-M10 IV are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the X10 has a lens built in, whereas the E-M10 IV is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the E-M10 IV and their specifications in the Micro Four Thirds Lens Catalog.
Concerning battery life, the X10 gets 270 shots out of its Fujifilm NP-50 battery, while the E-M10 IV can take 360 images on a single charge of its Olympus BLS-50 power pack. The power pack in the E-M10 IV can be charged via the USB port, which can be very convenient when travelling.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The X10 was launched at a lower price than the E-M10 IV, despite having a lens built in. 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. 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 X10 features a 2/3 sensor and the Olympus E-M10 IV a Four Thirds sensor. The sensor area in the E-M10 IV is 288 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 3.9 and 2.0. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

With 20.2MP, the E-M10 IV offers a higher resolution than the X10 (12MP), but the E-M10 IV nevertheless has larger individual pixels (pixel pitch of 3.34μm versus 2.20μm for the X10) due to its larger sensor. Moreover, the E-M10 IV is a much more recent model (by 8 years and 11 months) than the X10, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. 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 Olympus E-M10 IV implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-M10 IV for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm. The corresponding values for the Fujifilm X10 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.
The Fujifilm X10 has a native sensitivity range from ISO 100 to ISO 3200, which can be extended to ISO 100-12800. The corresponding ISO settings for the Olympus OM-D E-M10 Mark IV are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the E-M10 IV provides a better video resolution than the X10. It can shoot movie footage at 4K/30p, while the Fujifilm is limited to 1080/30p.
Feature comparison
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the E-M10 IV has an electronic viewfinder (2360k dots), while the X10 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The E-M10 IV has a touchscreen, while the X10 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
The E-M10 IV has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the X10 does not have a selfie-screen.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 E-M10 IV 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 Olympus E-M10 IV 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 X10 and the E-M10 IV write their files to SDXC cards. The E-M10 IV supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the X10 cannot take advantage of Ultra High Speed SD cards.
Connectivity comparison
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 X10 and Olympus OM-D E-M10 Mark IV and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-M10 IV offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the X10 does not provide wifi capability.
The E-M10 IV is a recent model that features in the current product line-up of Olympus. In contrast, the X10 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the X10 was succeeded by the Fujifilm X20. Further information on the features and operation of the X10 and E-M10 IV can be found, respectively, in the Fujifilm X10 Manual (free pdf) or the online Olympus E-M10 IV Manual.
Review summary
So what conclusions can be drawn? Which of the two cameras – the Fujifilm X10 or the Olympus E-M10 IV – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Fujifilm X10:
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- Ready to shoot: Has a lens built-in, whereas the E-M10 IV requires a separate lens.
- More compact: Is smaller (117x70mm vs 122x84mm) and thus needs less room in the bag.
- Less heavy: Is lighter even though it comes with a built-in lens (unlike the E-M10 IV).
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More heavily discounted: Has been available for much longer (launched in September 2011).

Reasons to prefer the Olympus OM-D E-M10 Mark IV:
- More detail: Has more megapixels (20.2 vs 12MP), which boosts linear resolution by 30%.
- Better image quality: Is equipped with a larger and more technologically advanced 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 (4K/30p vs 1080/30p).
- More framing info: Has an electronic viewfinder that displays shooting data.
- Larger screen: Has a bigger rear LCD (3.0" vs 2.8") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (1040k vs 460k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.

If the count of relative strengths (bullet points above) is taken as a measure, the E-M10 IV is the clear winner of the contest (22 : 6 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.
How about other alternatives? Do the specifications of the Fujifilm X10 and the Olympus E-M10 IV place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Mirrorless Interchangeable Lens Camera listings 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 remains incomplete and does no justice, for example, to the way the X10 or the E-M10 IV 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.
Expert reviews
This is where reviews by experts come in. 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 were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
