Canon 5D Mark III vs Olympus E-PL3

The Canon EOS 5D Mark III and the Olympus PEN E-PL3 are two digital cameras that were revealed to the public, respectively, in March 2012 and June 2011. The 5D Mark III is a DSLR, while the E-PL3 is a mirrorless interchangeable lens camera. The cameras are based on a full frame (5D Mark III) and a Four Thirds (E-PL3) sensor. The Canon has a resolution of 22.1 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 5D Mark III and the Olympus PEN E-PL3? 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 Mark III and the Olympus E-PL3 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.

The E-PL3 can be obtained in four different colors (black, silver, red, white), while the 5D Mark III is only available in black.

Compare 5D Mark III versus E-PL3 top
Comparison 5D Mark III or E-PL3 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-PL3 is considerably smaller (60 percent) than the Canon 5D Mark III. Moreover, the E-PL3 is substantially lighter (67 percent) than the 5D Mark III. It is worth mentioning in this context that the 5D Mark III is splash and dust resistant, while the E-PL3 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 Mark III) and the Micro Four Thirds Lens Catalog (E-PL3). Mirrorless cameras, such as the E-PL3, 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 Mark III gets 950 shots out of its LP-E6 battery, while the E-PL3 can take 300 images on a single charge of its BLS-5 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

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-PL3 was launched at a markedly lower price (by 83 percent) than the 5D Mark III, 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. 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. 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 Mark III features a full frame sensor and the Olympus E-PL3 a Four Thirds sensor. The sensor area in the E-PL3 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 Mark III has a native 3:2 aspect ratio, while the one in the E-PL3 offers a 4:3 aspect.

Canon 5D Mark III and Olympus E-PL3 sensor measures

With 22.1MP, the 5D Mark III offers a higher resolution than the E-PL3 (12.2MP), but the 5D Mark III nevertheless has larger individual pixels (pixel pitch of 6.25μm versus 4.29μm for the E-PL3) due to its larger sensor. Moreover, the 5D Mark III is a somewhat more recent model (by 8 months) than the E-PL3, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The resolution advantage of the Canon 5D Mark III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 5D Mark III for good quality output (200 dots per inch) amounts to 28.8 x 19.2 inches or 73.2 x 48.8 cm, for very good quality (250 dpi) 23 x 15.4 inches or 58.5 x 39 cm, and for excellent quality (300 dpi) 19.2 x 12.8 inches or 48.8 x 32.5 cm. The corresponding values for the Olympus E-PL3 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 Canon EOS 5D Mark III has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 50-102400. The corresponding ISO settings for the Olympus PEN E-PL3 are ISO 200 to ISO 12800 (no boost).

5D Mark III versus E-PL3 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under review, the 5D Mark III provides substantially higher image quality than the E-PL3, with an overall score that is 29 points higher. This advantage is based on 3.1 bits higher color depth, 1.4 EV in additional dynamic range, and 2.2 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the E-PL3 provides a faster frame rate than the 5D Mark III. It can shoot movie footage at 1080/60i, while the Canon is limited to 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the 5D Mark III has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the E-PL3 relies on live view and the rear LCD for framing. That said, the E-PL3 can be equipped with an optional viewfinder – the VF-2. The table below summarizes some of the other core capabilities of the Canon 5D Mark III and Olympus E-PL3 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 5D Mark III, but is missing on the E-PL3 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-PL3 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 Mark III does not have a selfie-screen.

The 5D Mark III writes its imaging data to Compact Flash or SDXC cards, while the E-PL3 uses SDXC cards. The 5D Mark III features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-PL3 only has one slot.

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 Mark III and Olympus PEN E-PL3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 5D Mark III has a microphone port, which is missing on the E-PL3. 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 Canon 5D Mark III (unlike the E-PL3) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 5D Mark III and the E-PL3 have been discontinued, but can regularly be found used on eBay. The E-PL3 was replaced by the Olympus E-PL5, while the 5D Mark III was followed by the Canon 5D Mark IV. 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.

Review summary

So how do things add up? Is the Canon 5D Mark III better than the Olympus E-PL3 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Advantages of the Olympus PEN E-PL3:

  • Better video: Provides higher movie framerates (1080/60i versus 1080/30p).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • More compact: Is smaller (110x64mm vs 152x116mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 637g or 67 percent) and is thus easier to take along.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • More affordable: Was introduced into a lower priced category (83 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in June 2011).

If the count of individual advantages (bullet points above) is taken as a guide, the 5D Mark III is the clear winner of the match-up (17 : 9 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 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 Mark III and the Olympus E-PL3 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 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 5D Mark III or the E-PL3 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 why expert reviews are important. 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
