Olympus PEN-F versus Olympus E-M10

The Olympus PEN-F and the Olympus OM-D E-M10 are two digital cameras that were announced, respectively, in January 2016 and January 2014. Both the PEN-F and the E-M10 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The PEN-F has a resolution of 20.2 megapixel, whereas the E-M10 provides 15.9 MP.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Olympus PEN-F and the Olympus E-M10. Three consecutive perspectives from the front, the top, and the back are presented. 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 PEN-F – 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 somewhat larger (8 percent) than the Olympus PEN-F. However, the E-M10 is slightly lighter (7 percent) than the PEN-F. Cameras that are intended for semi-professional or professional use are sometimes a bit bulkier in order to provide them with the necessary ruggedness. In this context, it is worth noting that neither the PEN-F 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.

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 comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-M10 was launched at a markedly lower price (by 42 percent) than the PEN-F, which puts it into a different market segment. 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. 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 are more costly to manufacture and tent to 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.

Sensor size

While the two cameras under review share the same sensor size, the PEN-F offers a higher resolution of 20.2 megapixel, compared with 15.9 MP of the E-M10. This megapixel advantage translates into a 13 percent gain in linear resolution. On the other hand, these sensor specs imply that the PEN-F has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.34μm versus 3.75μm for the E-M10). In this context, it should be noted, however, that the PEN-F is a somewhat more recent model (by 1 year and 11 months) than the E-M10, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size. 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

For most cameras, data on sensor performance has been reported by DXO Mark. 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 image quality. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the PEN-F provides a higher frame rate than the E-M10. It can shoot video footage at 1080/60p, while the E-M10 is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the PEN-F offers a substantially higher resolution than the one in the E-M10 (2360k vs 1440k dots). The following table reports on some other key feature differences and similarities of the Olympus PEN-F, the Olympus E-M10, and comparable cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

The PEN-F is a current model that online retailers, such as amazon, will have in stock. In contrast, the E-M10 has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the E-M10 was succeeded by the Olympus E-M10 II.

Summary

So how do things add up? Is the Olympus PEN-F better than the Olympus E-M10 or vice versa? Below is a summary of the relative strengths of each of the two contestants.


Reasons to prefer the Olympus PEN-F:

  • More detail: Offers more megapixels (20.2 vs 15.9MP) with a 13% higher linear resolution.
  • Better video: Provides higher movie framerates (1080/60p vs 1080/30p).
  • More detailed viewfinder: Has a higher resolution electronic viewfinder (2360k vs 1440k dots).
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Faster shutter: Has a higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (10 vs 8 flaps/sec) to capture the decisive moment.
  • More modern: Is somewhat more recent (announced 1 year and 11 months after the E-M10).

Advantages of the Olympus OM-D E-M10:

  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (42 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in January 2016).

If the number of relative strengths (bullet points above) is taken as a guide, the PEN-F is the clear winner of the match-up (7 : 3 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.

PEN-F 07:03 E-M10

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the PEN-F or the E-M10. 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 following table reports the overall rankings of the cameras as published by some of the major camera review sites. The full reviews are available, 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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
