Canon 77D versus Olympus E-5

The Canon EOS 77D and the Olympus E-5 are two digital cameras that were revealed to the public, respectively, in February 2017 and September 2010. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (77D) and a Four Thirds (E-5) sensor. The Canon has a resolution of 24 megapixel, whereas the Olympus provides 12.2 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon 77D vs Olympus E-5

The side-by-side display below illustrates the physical size and weight of the Canon 77D and the Olympus E-5. Three consecutive perspectives from the front, the top, and the back are presented. All size dimensions are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the 77D – represents 100 percent across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-5 is notably larger (27 percent) than the Canon 77D. Moreover, the E-5 is substantially heavier (62 percent) than the 77D. It is noteworthy in this context that the E-5 is splash and dust-proof, while the 77D 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 find an overview of optics for the two cameras in the Canon EF Lens Catalog (77D) and the Four Thirds Lens Catalog (E-5).

Concerning battery life, the 77D gets 600 shots out of its LP-E17 battery, while the E-5 can take 750 images on a single charge of its BLM-5 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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.

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 77D was launched at a markedly lower price (by 47 percent) than the E-5, 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.

 

Sensor comparison: Canon 77D vs Olympus E-5

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 77D features an APS-C sensor and the Olympus E-5 a Four Thirds sensor. The sensor area in the E-5 is 32 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 2.0. The sensor in the 77D has a native 3:2 aspect ratio, while the one in the E-5 offers a 4:3 aspect.

Canon 77D and Olympus E-5 sensor measures

With 24MP, the 77D offers a higher resolution than the E-5 (12.2MP), but the 77D has smaller individual pixels (pixel pitch of 3.72μm versus 4.29μm for the E-5). However, the 77D is a somewhat more recent model (by 6 years and 5 months) than the E-5, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.

77D versus E-5 MP

For most cameras, data on sensor performance has been reported by DXO Mark. 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 77D provides substantially higher image quality than the E-5, with an overall score that is 22 points higher. This advantage is based on 2 bits higher color depth, 2.8 EV in additional dynamic range, and 0.9 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 can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the 77D provides a higher video resolution than the E-5. It can shoot video footage at 1080/60p, while the Olympus is limited to 720/30p.

 

Feature comparison: Canon 77D vs Olympus E-5

Apart from body and sensor, cameras can and do differ across a variety of features. The 77D and the E-5 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The table below summarizes some of the other core capabilities of the Canon 77D and Olympus E-5 in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

The 77D is a current model that online retailers, such as amazon, will have in stock. In contrast, the E-5 has been discontinued (but it can be found pre-owned on eBay). There has not been a direct replacement model for the E-5 from Olympus.

Review summary: Canon 77D vs Olympus E-5

So what conclusions can be drawn? Which of the two cameras – the Canon 77D or the Olympus E-5 – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Advantages of the Canon EOS 77D:

  • More detail: Offers more megapixels (24 vs 12.2MP) with a 43% higher linear resolution.
  • Better image quality: Scores substantially higher (22 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (2 bits more color depth).
  • More dynamic range: Captures a larger spectrum of light and dark details (2.8 EV of extra DR).
  • Better low-light sensitivity: Requires less light for good images (0.9 stops ISO advantage).
  • Better video: Provides higher definition movie capture (1080/60p vs 720/30p).
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 920k dots).
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • Faster burst: Shoots at higher frequency (6 vs 5 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (131x100mm vs 142x117mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 333g or 38 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced category (47 percent cheaper at launch).
  • More modern: Reflects 6 years and 5 months of technical progress since the E-5 launch.

ilogo

Reasons to prefer the Olympus E-5:

  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Longer lasting: Gets more shots (750 versus 600) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More heavily discounted: Has been around for much longer (launched in September 2010).

If the count of relative strengths (bullet points above) is taken as a measure, the 77D is the clear winner of the match-up (13 : 5 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.

77D 13:05 E-5

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the 77D or the E-5 handle or 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 review scores listed above should be treated with care, though. The ratings are only valid when refering 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
