Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm X10 and the Olympus PEN E-P1? 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

An illustration of the physical size and weight of the Fujifilm X10 and the Olympus E-P1 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 size dimensions are rounded to the nearest millimeter.

The X10 can be obtained in two different colors (black, silver), while the E-P1 is available in three color-versions (black, silver, white).

Compare X10 versus E-P1 top
Comparison X10 or E-P1 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-P1 is somewhat larger (3 percent) than the Fujifilm X10. In this context, it is worth noting that neither the X10 nor the E-P1 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-P1 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-P1 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-P1 can take 300 images on a single charge of its BLS-1 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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

Any camera decision will obviously take relative prices into account. 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-P1, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

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. 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 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-P1 a Four Thirds sensor. The sensor area in the E-P1 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.

In terms of underlying technology, both cameras are build around CMOS sensors.

Fujifilm X10 and Olympus E-P1 sensor measures

With 12.2MP, the E-P1 offers a higher resolution than the X10 (12MP), but the E-P1 nevertheless has larger individual pixels (pixel pitch of 4.29μm versus 2.20μm for the X10) due to its larger sensor. However, the X10 is a much more recent model (by 2 years and 2 months) than the E-P1, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. 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-P1 are ISO 100 to ISO 6400 (no boost).

X10 versus E-P1 MP

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 consideration, the E-P1 has a markedly higher DXO score than the X10 (overall score 5 points higher), which will translate into better image quality. The advantage is based on 0.9 bits higher color depth, 0.9 EV of lower dynamic range, and 1.1 stops in additional low light sensitivity. 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 are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the X10 provides a higher video resolution than the E-P1. It can shoot video footage at 1080/30p, while the Olympus is limited to 720/30p.

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-P1 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Fujifilm X10 and Olympus E-P1 in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The X10 has one, while the E-P1 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.

The X10 writes its imaging data to SDXC cards, while the E-P1 uses SDHC cards.

Review summary

So how do things add up? Is there a clear favorite between the Fujifilm X10 and the Olympus E-P1? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Advantages of 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 (0.9 EV of extra DR).
  • Better video: Provides higher definition movie capture (1080/30p vs 720/30p).
  • Easier framing: Has an optical viewfinder for image composition and settings control.
  • More detailed LCD: Has a higher resolution rear screen (460k vs 230k dots).
  • Faster burst: Shoots at higher frequency (10 vs 3 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Has a lens built-in, whereas the E-P1 requires a separate lens.
  • Less heavy: Is lighter even though it comes with a built-in lens (unlike the E-P1).
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More modern: Reflects 2 years and 2 months of technical progress since the E-P1 launch.

ilogo

Reasons to prefer the Olympus PEN E-P1:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better image quality: Scores markedly higher (5 points) in the DXO overall evaluation.
  • Better low-light sensitivity: Can shoot in dim conditions (1.1 stops ISO advantage).
  • 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.
  • Longer lasting: Gets more shots (300 versus 270) out of a single battery charge.
  • More heavily discounted: Has been around for much longer (launched in June 2009).

If the count of relative strengths (bullet points above) is taken as a measure, the X10 is the clear winner of the match-up (11 : 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. 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 11:07 E-P1

How about other alternatives? Do the specifications of the Fujifilm X10 and the Olympus E-P1 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 says little about, for example, the shooting experience and imaging performance of the X10 and the E-P1 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.

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], 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 above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, 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.
