Canon 5D vs Olympus E-P7
The Canon EOS 5D and the Olympus PEN E-P7 are two digital cameras that were revealed to the public, respectively, in August 2005 and June 2021. The 5D is a DSLR, while the E-P7 is a mirrorless interchangeable lens camera. The cameras are based on a full frame (5D) and a Four Thirds (E-P7) sensor. The Canon has a resolution of 12.7 megapixels, whereas the Olympus provides 20.2 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 5D and the Olympus PEN E-P7? 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 physical size and weight of the Canon 5D and the Olympus E-P7 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-P7 can be obtained in three different colors (black, silver, white), while the 5D 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-P7 is considerably smaller (53 percent) than the Canon 5D. Moreover, the E-P7 is substantially lighter (62 percent) than the 5D. It is worth mentioning in this context that the 5D is splash and dust resistant, while the E-P7 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 (5D) and the Micro Four Thirds Lens Catalog (E-P7). Mirrorless cameras, such as the E-P7, 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.
Concerning battery life, the 5D gets 400 shots out of its Canon BP-511A battery, while the E-P7 can take 360 images on a single charge of its Olympus BLS-50 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, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will obviously take relative prices into account. 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-P7 was launched at a markedly lower price (by 76 percent) than the 5D, 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.
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. 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 5D features a full frame sensor and the Olympus E-P7 a Four Thirds sensor. The sensor area in the E-P7 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 5D has a native 3:2 aspect ratio, while the one in the E-P7 offers a 4:3 aspect.

Despite having a smaller sensor, the E-P7 offers a higher resolution of 20.2 megapixels, compared with 12.7 MP of the 5D. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.34μm versus 8.25μm for the 5D). However, it should be noted that the E-P7 is much more recent (by 15 years and 10 months) than the 5D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The resolution advantage of the Olympus E-P7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-P7 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm. The corresponding values for the Canon 5D are 21.8 x 14.6 inches or 55.5 x 37 cm for good quality, 17.5 x 11.6 inches or 44.4 x 29.6 cm for very good quality, and 14.6 x 9.7 inches or 37 x 24.7 cm for excellent quality prints.
The Canon EOS 5D has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 50-3200. The corresponding ISO settings for the Olympus PEN E-P7 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. 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 can also record movies. The E-P7 indeed provides for movie recording, while the 5D does not. The highest resolution format that the E-P7 can use is 4K/30p.
Feature comparison
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the 5D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the E-P7 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon 5D and Olympus E-P7 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 5D, but is missing on the E-P7 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 E-P7 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 5D 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, the E-P7 is one of those camera that have an additional 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-P7 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 5D writes its imaging data to Compact Flash cards, while the E-P7 uses SDXC 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 Canon EOS 5D and Olympus PEN E-P7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-P7 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 5D does not provide wifi capability.
Studio photographers will appreciate that the Canon 5D (unlike the E-P7) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The E-P7 is a recent model that features in the current product line-up of Olympus. In contrast, the 5D has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the 5D was succeeded by the Canon 5D Mark II. Further information on the features and operation of the 5D and E-P7 can be found, respectively, in the Canon 5D Manual (free pdf) or the online Olympus E-P7 Manual.
Review summary
So how do things add up? Is the Canon 5D better than the Olympus E-P7 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Canon EOS 5D:
- Easier framing: Has an optical viewfinder for image composition and settings control.

If the number of relative strengths (bullet points above) is taken as a guide, the E-P7 is the clear winner of the contest (19 : 7 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. 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 5D and the Olympus E-P7 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the 5D and the E-P7 in practical situations. 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.
Expert reviews
This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera 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 ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
