Olympus E-M5 II vs Canon 550D

The Olympus OM-D E-M5 Mark II and the Canon EOS 550D (labelled Canon T2i in some countries) are two digital cameras that were revealed to the public, respectively, in February 2015 and February 2010. The E-M5 II is a mirrorless interchangeable lens camera, while the 550D is a DSLR. The cameras are based on a Four Thirds (E-M5 II) and an APS-C (550D) sensor. The Olympus has a resolution of 15.9 megapixels, whereas the Canon provides 17.9 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Body comparison

The physical size and weight of the Olympus E-M5 II and the Canon 550D 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-M5 II can be obtained in two different colors (black, silver), while the 550D is only available in black.

Compare E-M5 II versus 550D top
Comparison E-M5 II or 550D rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 550D is notably larger (20 percent) than the Olympus E-M5 II. Moreover, the 550D is markedly heavier (13 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 550D 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 Micro Four Thirds Lens Catalog (E-M5 II) and the Canon EF Lens Catalog (550D). Mirrorless cameras, such as the Olympus E-M5 II, have moreover the advantage that they have a relatively short flange to focal plane distance and can thus use many lenses from other systems via adapters.

Concerning battery life, the E-M5 II gets 310 shots out of its Olympus BLN-1 battery, while the 550D can take 440 images on a single charge of its Canon LP-E8 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.

Note: 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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 550D was launched at a markedly lower price (by 36 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 tend to be more expensive and 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 550D an APS-C sensor. The sensor area in the 550D 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 550D offers a 3:2 aspect.

Olympus E-M5 II and Canon 550D sensor measures

With 17.9MP, the 550D offers a higher resolution than the E-M5 II (15.9MP), but the 550D nevertheless has larger individual pixels (pixel pitch of 4.31μm versus 3.76μm for the E-M5 II) due to its larger sensor. However, the E-M5 II is a much more recent model (by 4 years and 11 months) than the 550D, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Canon 550D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 550D for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inches or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inches or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inches or 43.9 x 29.3 cm. The corresponding values for the Olympus E-M5 II are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 cm for excellent quality prints.

Unlike the 550D, 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).

The Olympus OM-D E-M5 Mark II has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. The corresponding ISO settings for the Canon EOS 550D are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-12800.

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.

E-M5 II versus 550D MP

For many 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 E-M5 II has a notably higher overall DXO score than the 550D (overall score 7 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.9 bits higher color depth, 1 EV in additional dynamic range, and 0.1 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 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, but the E-M5 II provides a higher frame rate than the 550D. It can shoot video footage at 1080/60p, while the Canon is limited to 1080/30p.

Feature comparison

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), while the 550D 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 viewfinder in the E-M5 II offers a wider field of view (100%) than the one in the 550D (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the E-M5 II has a higher magnification (0.74x vs 0.54x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Olympus E-M5 II and Canon 550D in connection with corresponding information for a sample of similar cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One feature that differentiates the E-M5 II and the 550D is in-body image stabilization (IBIS). The E-M5 II reduces the risk of handshake-induced blur with all attached lenses, while the 550D offers no blur reduction with lenses that themselves do not provide optical image stabilization.

The E-M5 II has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the 550D 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-M5 II 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-M5 II 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.

Concerning the storage of imaging data, both the E-M5 II and the 550D write their files to SDXC cards. The E-M5 II supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the 550D cannot take advantage of Ultra High Speed SD cards.

It is notable that the E-M5 II offers wifi support, while the 550D does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Studio photographers will appreciate that the Olympus E-M5 II (unlike the 550D) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the E-M5 II and the 550D have been discontinued, but can regularly be found used on ebay. The 550D was replaced by the Canon 600D, while the E-M5 II was followed by the Olympus E-M5 III. Further information on the features and operation of the E-M5 II and 550D can be found, respectively, in the Olympus E-M5 II Manual (free pdf) or the online Canon 550D Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Olympus E-M5 II or the Canon 550D – has the upper hand? Is one clearly better than the other? 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.
  • Better image quality: Scores markedly higher (7 points) in the DXO overall assessment.
  • More dynamic range: Captures a larger spectrum of light and dark details (1 EV of extra DR).
  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.74x vs 0.54x).
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (10 vs 3.7 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More compact: Is smaller (124x85mm vs 129x98mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 61g or 12 percent) and hence easier to carry around.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • More legacy lens friendly: Can take a broad range of non-native lenses via adapters.

  • Faster buffer clearing: Supports Ultra High Speed (UHS-II) SDXC cards.
  • More modern: Reflects 4 years and 11 months of technical progress since the 550D launch.

ilogo

Reasons to prefer the Canon EOS 550D:

  • More detail: Has more megapixels (17.9 vs 15.9MP), which boosts linear resolution by 8%.
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Longer lasting: Gets more shots (440 versus 310) out of a single battery charge.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (36 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in February 2010).

If the count of relative strengths (bullet points above) is taken as a measure, the E-M5 II is the clear winner of the match-up (23 : 6 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

E-M5 II 23:06 550D

How about other alternatives? Do the specifications of the Olympus E-M5 II and the Canon 550D place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR 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 remains incomplete and does no justice, for example, to the way the E-M5 II or the 550D 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.

Expert reviews

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 (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.

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

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
