Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus OM-D E-M5 Mark II and the Olympus PEN E-PL9? 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.
The side-by-side display below illustrates the physical size and weight of the Olympus E-M5 II and the Olympus E-PL9. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth dimensions are rounded to the nearest millimeter.
The E-M5 II can be obtained in two different colors (black, silver), while the E-PL9 is available in four color-versions (black, brown, blue, white).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-PL9 is notably smaller (25 percent) than the Olympus E-M5 II. Moreover, the E-PL9 is markedly lighter (19 percent) than the E-M5 II. It is worth mentioning in this context that the E-M5 II is splash and dust resistant, while the E-PL9 does not feature any corresponding weather-sealing.
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 compare the optics available 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 following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 camera comparisons there.

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 E-PL9 was launched at a markedly lower price (by 50 percent) than the E-M5 II, 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.
The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels 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-PL9 uses a more advanced image processing engine (TruePic VIII) than the E-M5 II (TruePic VII), with benefits for noise reduction, color accuracy, and processing speed.
The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 15.9 megapixels. This similarity in sensor specs implies that both the E-M5 II and the E-PL9 have the same pixel density, as well as the same pixel size. It should, however, be noted that the E-PL9 is much more recent (by 3 years) than the E-M5 II, and its sensor will have benefitted from technological advances during this time.
Unlike the E-PL9, the E-M5 II has the capacity to capture high quality composite images (40MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).
The Olympus OM-D E-M5 Mark II has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. The corresponding ISO settings for the Olympus PEN E-PL9 are ISO 200 to ISO 6400, with the possibility to increase the ISO range to 100-25600.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 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. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the E-PL9 provides a better video resolution than the E-M5 II. It can shoot movie footage at 4K/30p, while the E-M5 II is limited to 1080/60p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the E-M5 II has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the E-PL9 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-M5 II, the Olympus E-PL9, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The E-PL9 has one, while the E-M5 II does not. While the built-in flash of the E-PL9 is not very powerful, it can at times be useful as a fill-in light.Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.
The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, both cameras under consideration feature an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The Olympus E-M5 II and the Olympus E-PL9 both have an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
Concerning the storage of imaging data, both the E-M5 II and the E-PL9 write their files to SDXC cards. The E-M5 II supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the E-PL9 can use UHS-I cards (up to 104 MB/s).
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 Olympus OM-D E-M5 Mark II and Olympus PEN E-PL9 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-M5 II has a microphone port, which is missing on the E-PL9. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Studio photographers will appreciate that the Olympus E-M5 II (unlike the E-PL9) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the E-M5 II and the E-PL9 are recent models that are part of the current product line-up. The E-M5 II replaced the earlier Olympus E-M5, while the E-PL9 followed on from the Olympus E-PL8. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Olympus website.
So what conclusions can be drawn? Which of the two cameras – the Olympus E-M5 II or the Olympus E-PL9 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Olympus OM-D E-M5 Mark II:
- High quality composites: Can combine several shots after pixel-shifting its sensor.
- Better sound: Can connect to an external microphone for higher quality sound recording.
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (10 vs 8.6 flaps/sec) to capture the decisive moment.
- Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
- More heavily discounted: Has been available for much longer (launched in February 2015).
Arguments in favor of the Olympus PEN E-PL9:
- Better jpgs: Has a more modern image processing engine (TruePic VIII vs TruePic VII).
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
- More compact: Is smaller (117x68mm vs 124x85mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 89g or 19 percent) and is thus easier to take along.
- Longer lasting: Gets more shots (350 versus 310) out of a single battery charge.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- Easier wireless transfer: Supports Bluetooth for image sharing without cables.
- More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).
- More modern: Reflects 3 years of technical progress since the E-M5 II launch.
If the count of individual advantages (bullet points above) is taken as a guide, the E-M5 II comes out slightly ahead of the E-PL9 (10 : 9 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.
How about other alternatives? Do the specifications of the Olympus E-M5 II and the Olympus E-PL9 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing 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 E-M5 II and the E-PL9 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.
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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
