Canon 7D vs Olympus E-M10

The Canon EOS 7D and the Olympus OM-D E-M10 are two digital cameras that were revealed to the public, respectively, in September 2009 and January 2014. The 7D is a DSLR, while the E-M10 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (7D) and a Four Thirds (E-M10) sensor. The Canon has a resolution of 17.9 megapixels, whereas the Olympus provides 15.9 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 7D and the Olympus OM-D E-M10? 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: Canon 7D vs Olympus E-M10

The side-by-side display below illustrates the physical size and weight of the Canon 7D and the Olympus E-M10. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter.

The E-M10 can be obtained in two different colors (black, silver), while the 7D is only available in black.

Size Canon 7D vs Olympus E-M10
Compare 7D versus E-M10 top
Comparison 7D or E-M10 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-M10 is considerably smaller (41 percent) than the Canon 7D. Moreover, the E-M10 is substantially lighter (54 percent) than the 7D. It is worth mentioning in this context that the 7D is splash and dust resistant, while the E-M10 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 (7D) and the Micro Four Thirds Lens Catalog (E-M10). Mirrorless cameras, such as the E-M10, 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 7D gets 800 shots out of its LP-E6 battery, while the E-M10 can take 320 images on a single charge of its BLS-5 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

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 E-M10 was launched at a markedly lower price (by 59 percent) than the 7D, 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.

 

Sensor comparison: Canon 7D vs Olympus E-M10

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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon 7D features an APS-C sensor and the Olympus E-M10 a Four Thirds sensor. The sensor area in the E-M10 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 7D has a native 3:2 aspect ratio, while the one in the E-M10 offers a 4:3 aspect.

Canon 7D and Olympus E-M10 sensor measures

With 17.9MP, the 7D offers a higher resolution than the E-M10 (15.9MP), but the 7D nevertheless has larger individual pixels (pixel pitch of 4.31μm versus 3.76μm for the E-M10) due to its larger sensor. However, the E-M10 is a much more recent model (by 4 years and 4 months) than the 7D, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the E-M10 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Canon 7D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 7D for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inch or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inch or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inch or 43.9 x 29.3 cm. The corresponding values for the Olympus E-M10 are 23 x 17.3 inch or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inch or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inch or 39 x 29.3 cm for excellent quality prints.

The Canon EOS 7D has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-12800. The corresponding ISO settings for the Olympus OM-D E-M10 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

7D versus E-M10 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. Of the two cameras under consideration, the E-M10 has a markedly higher DXO score than the 7D (overall score 6 points higher), which will translate into better image quality. The advantage is based on 0.8 bits higher color depth, 0.6 EV in additional dynamic range, and -0 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. 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 (1080/30p).

 

Feature comparison: Canon 7D vs Olympus E-M10

Apart from body and sensor, cameras can and do differ across a range of features. For example, the E-M10 has an electronic viewfinder (1440k dots), while the 7D has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the 7D has a higher magnification than the one of the E-M10 (0.63x vs 0.58x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Canon 7D, the Olympus E-M10, and comparable cameras.

One feature that is present on the 7D, but is missing on the E-M10 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 Olympus E-M10 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 7D writes its imaging data to Compact Flash cards, while the E-M10 uses SDXC cards.

 

Connectivity comparison: Canon 7D vs Olympus E-M10

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 7D and Olympus OM-D E-M10 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 7D has a microphone port, which is missing on the E-M10. 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 7D (unlike the E-M10) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 7D and the E-M10 have been discontinued, but can regularly be found used on eBay. The 7D was replaced by the Canon 7D Mark II, while the E-M10 was followed by the Olympus E-M10 II. 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: Canon 7D vs Olympus E-M10

So what is the bottom line? Is there a clear favorite between the Canon 7D and the Olympus E-M10? Which camera is better? The listing below highlights the relative strengths of the two models.

ilogo

  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.63x vs 0.58x).
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Longer lasting: Can take more shots (800 versus 320) on a single battery charge.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • More heavily discounted: Has been available for much longer (launched in September 2009).

ilogo

Reasons to prefer the Olympus OM-D E-M10:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Scores markedly higher (6 points) in the DXO overall evaluation.
  • More dynamic range: Captures a broader range of light and dark details (0.6 EV of extra DR).
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More detailed LCD: Has a higher resolution rear screen (1037k vs 920k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More compact: Is smaller (119x82mm vs 148x111mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 464g or 54 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.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • More affordable: Was introduced into a lower priced category (59 percent cheaper at launch).
  • More modern: Reflects 4 years and 4 months of technical progress since the 7D launch.

If the count of individual advantages (bullet points above) is taken as a guide, the E-M10 is the clear winner of the contest (15 : 11 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 7D and the Olympus E-M10 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 7D or the E-M10 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: Canon 7D vs Olympus E-M10

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.

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

The review scores listed above should be treated with care, 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.
