Fujifilm X100 versus Olympus E-M10

The Fujifilm FinePix X100 and the Olympus OM-D E-M10 are two digital cameras that were revealed to the public, respectively, in September 2010 and January 2014. The X100 is a fixed lens compact, while the E-M10 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (X100) and a Four Thirds (E-M10) sensor. The Fujifilm has a resolution of 12.2 megapixel, whereas the Olympus provides 15.9 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: Fujifilm X100 vs Olympus E-M10

The physical size and weight of the Fujifilm X100 and the Olympus E-M10 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 size dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the X100 – 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 Olympus E-M10 is somewhat larger (3 percent) than the Fujifilm X100. In this context, it is worth noting that neither the X100 nor the E-M10 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the X100 has a lens build in, whereas the E-M10 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 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the X100 gets 300 shots out of its NP-95 battery, while the E-M10 can take 320 images on a single charge of its BLS-5 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

The camera’s price is obviously a critical decision-making factor. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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.

 

Sensor comparison: Fujifilm X100 vs Olympus E-M10

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. 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 Fujifilm X100 features an APS-C sensor and the Olympus E-M10 a Four Thirds sensor. The sensor area in the E-M10 is 40 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 X100 has a native 3:2 aspect ratio, while the one in the E-M10 offers a 4:3 aspect.

Fujifilm X100 and Olympus E-M10 sensor measures

Despite having a smaller sensor, the E-M10 offers a higher resolution of 15.9 megapixel, compared with 12.2 MP of the X100. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.76μm versus 5.53μm for the X100). However, it should be noted that the E-M10 is much more recent (by 3 years and 4 months) than the X100, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. 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.

X100 versus E-M10 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality.

  • More detailed LCD: Has a higher resolution rear screen (1037k 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.
  • Faster burst: Shoots at higher frequency (8 vs 5 flaps/sec) to capture the decisive moment.
  • More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More modern: Reflects 3 years and 4 months of technical progress since the X100 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the E-M10 is the clear winner of the contest (10 : 2 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.

X100 02:10 E-M10

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 X100 or the E-M10 handle or perform in practice. 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 summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The above review scores should be interpreted with care, 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
