Olympus E-P1 versus Olympus E-M10

The Olympus PEN E-P1 and the Olympus OM-D E-M10 are two digital cameras that were revealed to the public, respectively, in June 2009 and January 2014. Both the E-P1 and the E-M10 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The E-P1 has a resolution of 12.2 megapixel, whereas the E-M10 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: Olympus E-P1 vs Olympus E-M10

The physical size and weight of the Olympus E-P1 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 consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures 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 E-P1 – represents the basis or 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 notably larger (15 percent) than the Olympus E-P1. Moreover, the E-M10 is markedly heavier (12 percent) than the E-P1. In this context, it is worth noting that neither the E-P1 nor the E-M10 are weather-sealed.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can find an overview of suitable optics in the Micro Four Thirds Lens Catalog. Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.

Concerning battery life, the E-P1 gets 300 shots out of its BLS-1 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. If you would like to visualize and compare a different camera combination, just use the right or left arrows in the table to switch to the respective camera.

The camera’s price is obviously a critical decision-making factor. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The E-M10 was launched at a somewhat lower price (by 13 percent) than the E-P1, which makes it more attractive for photographers on a tight budget. 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-P1 vs Olympus E-M10

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

Both cameras under consideration feature a Four Thirds sensor and have a format factor (sometimes also referred to as "crop factor") of 2.0. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Technology-wise, the E-M10 uses a more advanced image processing engine (TruePic VII) than the E-P1 (TruePic V), with benefits for noise reduction, color accuracy, and processing speed.

Olympus E-P1 and Olympus E-M10 sensor measures

While the two cameras under review share the same sensor size, the E-M10 offers a higher resolution of 15.9 megapixel, compared with 12.2 MP of the E-P1. This megapixel advantage translates into a 14 percent gain in linear resolution. On the other hand, these sensor specs imply that the E-M10 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.76μm versus 4.29μm for the E-P1). However, it should be noted that the E-M10 is much more recent (by 4 years and 7 months) than the E-P1, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size. Coming back to sensor resolution, it should be mentioned that the E-M10 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

E-P1 versus E-M10 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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-M10 offers substantially better image quality than the E-P1 (overall score 17 points higher). The advantage is based on 1.4 bits higher color depth, 1.9 EV in additional dynamic range, and 0.7 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the E-M10 provides a better video resolution than the E-P1. It can shoot movie footage at 1080/30p, while the E-P1 is limited to 720/30p.

 

Feature comparison: Olympus E-P1 vs Olympus E-M10

Beyond body and sensor, cameras can and do differ across a range of features. For example, the E-M10 has an electronic viewfinder (1440k dots), which can be very helpful when shooting in bright sunlight. In contrast, the E-P1 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Olympus E-P1, the Olympus E-M10, and comparable cameras.

Review summary: Olympus E-P1 vs Olympus E-M10

So what conclusions can be drawn? Which of the two cameras – the Olympus E-P1 or the Olympus E-M10 – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


Reasons to prefer the Olympus PEN E-P1:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More compact: Is smaller (121x70mm vs 119x82mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 41g or 10 percent) and hence easier to carry around.
  • More heavily discounted: Has been available for much longer (launched in June 2009).


Arguments in favor of the Olympus OM-D E-M10:

  • More detail: Has more megapixels (15.9 vs 12.2MP), which boosts linear resolution by 14%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Scores substantially higher (17 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.4 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (1.9 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (0.7 stops ISO advantage).
  • Better jpgs: Has a more modern image processing engine (TruePic VII vs TruePic V).
  • Better video: Provides higher definition movie capture (1080/30p vs 720/30p).
  • Easier framing: Has an electronic viewfinder for image framing and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1037k vs 230k 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 3 flaps/sec) to capture the decisive moment.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • Easier file upload: Has wifi build in for automatic backup or image transfer to the web.
  • More affordable: Was released into a lower priced segment (13 percent cheaper at launch).
  • More modern: Reflects 4 years and 7 months of technical progress since the E-P1 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the E-M10 is the clear winner of the contest (17 : 4 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.

E-P1 04:17 E-M10

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the E-P1 or the E-M10. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable. 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).

Care should be taken when interpreting the review scores above, 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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
