Canon 6D Mark II vs Olympus E-P1
The Canon EOS 6D Mark II and the Olympus PEN E-P1 are two enthusiast cameras that were officially introduced, respectively, in June 2017 and June 2009. The 6D Mark II is a DSLR, while the E-P1 is a mirrorless interchangeable lens camera. The cameras are based on a full frame (6D Mark II) and a Four Thirds (E-P1) sensor. The Canon has a resolution of 26 megapixels, whereas the Olympus provides 12.2 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 Canon EOS 6D Mark II 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.
The physical size and weight of the Canon 6D Mark II and the Olympus E-P1 are illustrated in the side-by-side display below. 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 size dimensions are rounded to the nearest millimeter.
The E-P1 can be obtained in three different colors (black, silver, white), while the 6D Mark II 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-P1 is considerably smaller (47 percent) than the Canon 6D Mark II. Moreover, the E-P1 is substantially lighter (54 percent) than the 6D Mark II. It is worth mentioning in this context that the 6D Mark II is splash and dust resistant, while the E-P1 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 Canon EF Lens Catalog (6D Mark II) and the Micro Four Thirds Lens Catalog (E-P1). Mirrorless cameras, such as the E-P1, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.

Any camera decision will naturally be influenced heavily by the price. 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-P1 was launched at a markedly lower price (by 60 percent) than the 6D Mark 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.
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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon 6D Mark II features a full frame sensor and the Olympus E-P1 a Four Thirds sensor. The sensor area in the E-P1 is 74 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 6D Mark II has a native 3:2 aspect ratio, while the one in the E-P1 offers a 4:3 aspect.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
With 26MP, the 6D Mark II offers a higher resolution than the E-P1 (12.2MP), but the 6D Mark II nevertheless has larger individual pixels (pixel pitch of 5.76μm versus 4.29μm for the E-P1) due to its larger sensor. Moreover, the 6D Mark II is a much more recent model (by 8 years) than the E-P1, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
The resolution advantage of the Canon 6D Mark II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 6D Mark II for good quality output (200 dots per inch) amounts to 31.2 x 20.8 inches or 79.2 x 52.8 cm, for very good quality (250 dpi) 25 x 16.6 inches or 63.4 x 42.3 cm, and for excellent quality (300 dpi) 20.8 x 13.9 inches or 52.8 x 35.2 cm. The corresponding values for the Olympus E-P1 are 20.2 x 15.1 inches or 51.2 x 38.4 cm for good quality, 16.1 x 12.1 inches or 41 x 30.7 cm for very good quality, and 13.4 x 10.1 inches or 34.1 x 25.6 cm for excellent quality prints.
The 6D Mark II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS 6D Mark II has a native sensitivity range from ISO 100 to ISO 40000, which can be extended to ISO 50-102400. The corresponding ISO settings for the Olympus PEN E-P1 are ISO 100 to ISO 6400 (no boost).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). Of the two cameras under review, the 6D Mark II provides substantially higher image quality than the E-P1, with an overall score that is 30 points higher. This advantage is based on 3 bits higher color depth, 1.5 EV in additional dynamic range, and 2.4 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 also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the 6D Mark II provides a higher video resolution than the E-P1. It can shoot video footage at 1080/60p, while the Olympus is limited to 720/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the 6D Mark II 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 adjacent table lists some of the other core features of the Canon 6D Mark II and Olympus E-P1 along with similar information for a selection of comparators.

One feature that is present on the 6D Mark II, but is missing on the E-P1 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.The 6D Mark II has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the E-P1 does not have a selfie-screen.
The Canon 6D Mark II 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 6D Mark II writes its imaging data to SDXC cards, while the E-P1 uses SDHC cards. The 6D Mark II supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the E-P1 cannot take advantage of Ultra High Speed SD cards.
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 Canon EOS 6D Mark II and Olympus PEN E-P1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 6D Mark II has a microphone port, which is missing on the E-P1. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Travel and landscape photographers will find it useful that the 6D Mark II has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.
The 6D Mark II is a recent model that features in the current product line-up of Canon. In contrast, the E-P1 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the E-P1 was succeeded by the Olympus E-P2. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Olympus websites.
So how do things add up? Which of the two cameras – the Canon 6D Mark II or the Olympus E-P1 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

If the count of individual advantages (bullet points above) is taken as a guide, the 6D Mark II is the clear winner of the match-up (24 : 6 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 Canon 6D Mark II and the Olympus E-P1 place the cameras among the top in their class? Find out in the latest Best DSLR 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the 6D Mark II or the E-P1 perform in practice. 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 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 (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.

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. 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.
