Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm X10 and the Olympus PEN E-PM1? 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-PM1 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 width, height and depth dimensions are rounded to the nearest millimeter.

The X10 can be obtained in two different colors (black, silver), while the E-PM1 is available in six color-versions (black, silver, brown, pink, purple, white).

Size Fujifilm X10 vs Olympus E-PM1
Compare X10 versus E-PM1 top
Comparison X10 or E-PM1 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-PM1 is notably smaller (14 percent) than the Fujifilm X10. In this context, it is worth noting that neither the X10 nor the E-PM1 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-PM1 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-PM1 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the X10 gets 270 shots out of its NP-50 battery, while the E-PM1 can take 330 images on a single charge of its BLS-5 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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

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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Fujifilm X10 features a 2/3 sensor and the Olympus E-PM1 a Four Thirds sensor. The sensor area in the E-PM1 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.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

Fujifilm X10 and Olympus E-PM1 sensor measures

With 12.2MP, the E-PM1 offers a higher resolution than the X10 (12MP), but the E-PM1 nevertheless has larger individual pixels (pixel pitch of 4.29μm versus 2.20μm for the X10) due to its larger sensor. It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation. Coming back to sensor resolution, it should be mentioned that the X10 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

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 PEN E-PM1 are ISO 100 to ISO 12800 (no boost).

X10 versus E-PM1 MP

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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the E-PM1 provides a faster frame rate than the X10. It can shoot movie footage at 1080/60i, while the Fujifilm is limited to 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the X10 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the E-PM1 relies on live view and the rear LCD for framing. That said, the E-PM1 can be equipped with an optional viewfinder – the VF-2. The following table reports on some other key feature differences and similarities of the Fujifilm X10, the Olympus E-PM1, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The X10 has one, while the E-PM1 does not. While the built-in flash of the X10 is not very powerful, it can at times be useful as a fill-in light.

Concerning the storage of imaging data, both the X10 and the E-PM1 write their files to SDXC 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 PEN E-PM1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Review summary

So what is the bottom line? Is there a clear favorite between the Fujifilm X10 and the Olympus E-PM1? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Reasons to prefer the Fujifilm X10:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • More dynamic range: Captures a larger spectrum of light and dark details (1 EV of extra DR).
  • Easier framing: Has an optical viewfinder for image composition and settings control.
  • Faster burst: Shoots at higher frequency (10 vs 5.5 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Has a lens built-in, whereas the E-PM1 requires a separate lens.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.

ilogo

Arguments in favor of the Olympus PEN E-PM1:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better low-light sensitivity: Can shoot in dim conditions (1 stops ISO advantage).
  • Better video: Provides higher movie framerates (1080/60i versus 1080/30p).
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.8") for image review and settings control.
  • More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
  • More compact: Is smaller (110x64mm vs 117x70mm) and will fit more readily into a bag.
  • Longer lasting: Gets more shots (330 versus 270) out of a single battery charge.

If the count of relative strengths (bullet points above) is taken as a measure, the E-PM1 comes out slightly ahead of the X10 (7 : 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

X10 06:07 E-PM1

How about other alternatives? Do the specifications of the Fujifilm X10 and the Olympus E-PM1 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 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 X10 or the E-PM1 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.

Expert reviews

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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
