Olympus E-M5 II versus Canon M6

The Olympus OM-D E-M5 Mark II and the Canon EOS M6 are two digital cameras that were revealed to the public, respectively, in February 2015 and February 2017. Both the E-M5 II and the M6 are mirrorless interchangeable lens cameras that are based on a Four Thirds (E-M5 II) and an APS-C (M6) sensor. The Olympus has a resolution of 15.9 megapixel, whereas the Canon provides 24 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: Olympus E-M5 II vs Canon M6

The side-by-side display below illustrates the physical size and weight of the Olympus E-M5 II and the Canon M6. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter. You can also toggle the display 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 side – the E-M5 II – represents the basis for the calculations 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 Canon M6 is notably smaller (28 percent) than the Olympus E-M5 II. Moreover, the M6 is markedly lighter (17 percent) than the E-M5 II. It is worth mentioning in this context that the E-M5 II is splash and dust resistant, while the M6 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. Hence, you might want to study the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the E-M5 II gets 310 shots out of its BLN-1 battery, while the M6 can take 295 images on a single charge of its LP-E17 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 M6 was launched at a markedly lower price (by 29 percent) than the E-M5 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Olympus E-M5 II vs Canon M6

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 Olympus E-M5 II features a Four Thirds sensor and the Canon M6 an APS-C sensor. The sensor area in the M6 is 48 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.6. The sensor in the E-M5 II has a native 4:3 aspect ratio, while the one in the M6 offers a 3:2 aspect.

Olympus E-M5 II and Canon M6 sensor measures

With 24MP, the M6 offers a higher resolution than the E-M5 II (15.9MP), but the M6 has marginally smaller individual pixels (pixel pitch of 3.72μm versus 3.76μm for the E-M5 II). Yet, the M6 is a much more recent model (by 2 years) than the E-M5 II, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

Unlike the M6, the E-M5 II has the capacity to capture high quality composite images (40MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

E-M5 II versus M6 MP

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 cannot only take still pictures, but also record videos. 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 (1080/60p).

 

Feature comparison: Olympus E-M5 II vs Canon M6

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the E-M5 II has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the M6 relies on live view and the rear LCD for framing. That said, the M6 can be equipped with an optional viewfinder – the EVF-DC2. The table below summarizes some of the other core capabilities of the Olympus E-M5 II and Canon M6 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 reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the E-M5 II features an electronic shutter, which makes silent shooting and higher burst speeds possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

Both the E-M5 II and the M6 are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The E-M5 II replaced the earlier Olympus E-M5, while the M6 followed on from the Canon M5.

Review summary: Olympus E-M5 II vs Canon M6

So what is the bottom line? Which of the two cameras – the Olympus E-M5 II or the Canon M6 – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Advantages of the Olympus OM-D E-M5 Mark II:

  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Easier framing: Has an electronic viewfinder for image framing and settings control.
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Sharper images: Has hand-shake reducing image stabilization build-in.
  • More heavily discounted: Has been available for much longer (launched in February 2015).

ilogo

Reasons to prefer the Canon EOS M6:

  • More detail: Has more megapixels (24 vs 15.9MP), which boosts linear resolution by 25%.
  • Better image quality: Is equipped with a larger and more technologically advanced sensor.
  • More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
  • More compact: Is smaller (112x68mm vs 124x85mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 79g or 17 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 (29 percent cheaper at launch).
  • More modern: Reflects 2 years of technical progress since the E-M5 II launch.

If the count of individual advantages (bullet points above) is taken as a guide, the match-up finishes in a tie (8 points each). 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.

E-M5 II 08:08 M6

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the E-M5 II or the M6. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate. This is why expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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. 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.
