Olympus E-M10 II versus Fujifilm X10

The Olympus OM-D E-M10 Mark II and the Fujifilm X10 are two digital cameras that were officially introduced, respectively, in August 2015 and September 2011. The E-M10 II is a mirrorless interchangeable lens camera, while the X10 is a fixed lens compact. The cameras are based on a Four Thirds (E-M10 II) and a 2/3 (X10) sensor. The Olympus has a resolution of 15.9 megapixel, whereas the Fujifilm provides 12 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Olympus E-M10 II vs Fujifilm X10

An illustration of the physical size and weight of the Olympus E-M10 II and the Fujifilm X10 is provided in the side-by-side display below. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the E-M10 II – represents 100 percent across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Fujifilm X10 is notably smaller (18 percent) than the Olympus E-M10 II. In this context, it is worth noting that neither the E-M10 II nor the X10 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the X10 has a lens build in, whereas the E-M10 II is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can find an overview of optics for the E-M10 II and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the E-M10 II gets 320 shots out of its BLS-50 battery, while the X10 can take 270 images on a single charge of its NP-50 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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.

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 II, despite having a lens build 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.


Sensor comparison: Olympus E-M10 II vs Fujifilm X10

The size of the sensor inside a digital camera is one of the key determinants 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 Olympus E-M10 II features a Four Thirds sensor and the Fujifilm X10 a 2/3 sensor. The sensor area in the X10 is 74 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 3.9. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Sensor size

With 15.9MP, the E-M10 II offers a higher resolution than the X10 (12MP), but the E-M10 II nevertheless has larger individual pixels (pixel pitch of 3.76μm versus 2.20μm for the X10) due to its larger sensor. Moreover, the E-M10 II is a somewhat more recent model (by 3 years and 11 months) than the X10, and its sensor might 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

Sensor resolution

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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. Of the two cameras under review, the E-M10 II provides substantially higher image quality than the X10, with an overall score that is 23 points higher. This advantage is based on 2.6 bits higher color depth, 1.2 EV in additional dynamic range, and 1.8 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

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 II provides a higher frame rate than the X10. It can shoot video footage at 1080/60p, while the Fujifilm is limited to 1080/30p.

Feature comparison: Olympus E-M10 II vs Fujifilm X10

Apart from body and sensor, cameras can and do differ across a range of features. For example, the E-M10 II 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. The following table reports on some other key feature differences and similarities of the Olympus E-M10 II, the Fujifilm X10, and comparable cameras.

Arguments in favor of the Fujifilm X10:

  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Faster burst: Shoots at higher frequency (10 vs 8 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Has an integrated lens, whereas the E-M10 II necessitates an extra lens.
  • More compact: Is smaller (117x70mm vs 120x83mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens build in (unlike the E-M10 II).
  • More affordable: Was introduced at a lower price, despite coming with a build-in lens.
  • More heavily discounted: Has been around for much longer (launched in September 2011).

If the count of individual advantages (bullet points above) is taken as a guide, the E-M10 II is the clear winner of the match-up (14 : 7 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.

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the E-M10 II and the X10 in practical situations. 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 where reviews by experts come in. The following table reports the overall rankings of the cameras as published by some of the major camera review sites. You can find the full text of the reviews, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when refering to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
