Sony A9 vs Olympus E-PL9
The Sony Alpha A9 and the Olympus PEN E-PL9 are two digital cameras that were revealed to the public, respectively, in April 2017 and February 2018. Both the A9 and the E-PL9 are mirrorless interchangeable lens cameras that are based on a full frame (A9) and a Four Thirds (E-PL9) sensor. The Sony has a resolution of 24 megapixels, whereas the Olympus provides 15.9 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Alpha A9 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.
Body comparison
The side-by-side display below illustrates the physical size and weight of the Sony A9 and the Olympus E-PL9. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter.
The E-PL9 can be obtained in four different colors (black, brown, blue, white), while the A9 is only available in black.
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 considerably smaller (35 percent) than the Sony A9. Moreover, the E-PL9 is substantially lighter (44 percent) than the A9. It is worth mentioning in this context that the A9 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Sony FE Lens Catalog (A9) and the Micro Four Thirds Lens Catalog (E-PL9). 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 A9 gets 650 shots out of its Sony NP-FZ100 battery, while the E-PL9 can take 350 images on a single charge of its Olympus BLS-50 power pack. The power pack in the A9 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

The price is, of course, an important factor in any camera decision. 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 87 percent) than the A9, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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.
Sensor comparison
The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Sony A9 features a full frame sensor and the Olympus E-PL9 a Four Thirds sensor. The sensor area in the E-PL9 is 73 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.0. The sensor in the A9 has a native 3:2 aspect ratio, while the one in the E-PL9 offers a 4:3 aspect.
With 24MP, the A9 offers a higher resolution than the E-PL9 (15.9MP), but the A9 nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 3.76μm for the E-PL9) due to its larger sensor. However, the E-PL9 is a somewhat more recent model (by 9 months) than the A9, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.
The resolution advantage of the Sony A9 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A9 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Olympus E-PL9 are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 cm for excellent quality prints.
The A9 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Sony Alpha A9 has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 50-204800. 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.
In terms of underlying technology, the A9 is build around a Stacked BSI-CMOS sensor, while the E-PL9 uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.
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.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (4K/30p).
Feature comparison
Apart from body and sensor, cameras can and do differ across a range of features. For example, the A9 has an electronic viewfinder (3686k 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 Sony A9, the Olympus E-PL9, and comparable cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one. |
One difference between the cameras concerns the presence of an on-board flash. The E-PL9 has one, while the A9 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.
The E-PL9 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the A9 does not have a selfie-screen.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-PL9 has 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.
The A9 writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the E-PL9 uses SDXC cards. The A9 features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-PL9 only has one slot. The A9 supports UHS-II cards (on its first slot), while the E-PL9 can use UHS-I 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 Sony Alpha A9 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 A9 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 Sony A9 (unlike the E-PL9) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the A9 and the E-PL9 have been discontinued, but can regularly be found used on ebay. The A9 was replaced by the Sony A9 II, while the E-PL9 was followed by the Olympus E-PL10. Further information on the features and operation of the A9 and E-PL9 can be found, respectively, in the Sony A9 Manual (free pdf) or the online Olympus E-PL9 Manual.
Review summary
So what is the bottom line? Is there a clear favorite between the Sony A9 and the Olympus E-PL9? Which camera is better? The listing below highlights the relative strengths of the two models.

- More heavily discounted: Has been on the market for longer (launched in April 2017).
Reasons to prefer the Olympus PEN E-PL9:
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- More compact: Is smaller (117x68mm vs 127x96mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 293g or 44 percent) and is thus easier to take along.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- More affordable: Was introduced into a lower priced category (87 percent cheaper at launch).
- More modern: Was introduced somewhat (9 months) more recently.
If the count of individual advantages (bullet points above) is taken as a guide, the A9 is the clear winner of the match-up (20 : 7 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding 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 Sony A9 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 remains incomplete and does no justice, for example, to the way the A9 or the E-PL9 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 where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

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. 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.
