Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX720 HS and the Olympus OM-D E-M5? 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

An illustration of the physical size and weight of the Canon SX720 and the Olympus E-M5 is provided 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 width, height and depth dimensions are rounded to the nearest millimeter.

The SX720 can be obtained in two different colors (black, red), while the E-M5 is also available in two color-versions, but different ones (black, silver).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-M5 is considerably larger (54 percent) than the Canon SX720. It is noteworthy in this context that the E-M5 is splash and dust-proof, while the SX720 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX720 has a lens built in, whereas the E-M5 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the E-M5 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the SX720 gets 250 shots out of its Canon NB-13L battery, while the E-M5 can take 360 images on a single charge of its Olympus BLN-1 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The SX720 was launched at a lower price than the E-M5, despite having a lens built in. 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

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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon SX720 features a 1/2.3-inch sensor and the Olympus E-M5 a Four Thirds sensor. The sensor area in the E-M5 is 704 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 2.0. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Despite having a smaller sensor, the Canon SX720 offers a higher resolution of 20.2 megapixels, compared with 15.9 MP of the Olympus E-M5. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.18μm versus 3.76μm for the E-M5). However, it should be noted that the SX720 is much more recent (by 4 years) than the E-M5, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the SX720 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Canon SX720 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SX720 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm. The corresponding values for the Olympus E-M5 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.

The Canon PowerShot SX720 HS has a native sensitivity range from ISO 80 to ISO 3200. The corresponding ISO settings for the Olympus OM-D E-M5 are ISO 200 to ISO 25600 (no boost).

In terms of underlying technology, the SX720 is build around a BSI-CMOS sensor, while the E-M5 uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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"). 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 can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the SX720 provides a higher frame rate than the E-M5. It can shoot video footage at 1080/60p, while the Olympus is limited to 1080/60i.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the E-M5 has an electronic viewfinder (1440k dots), which can be very helpful when shooting in bright sunlight. In contrast, the SX720 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Canon SX720, the Olympus E-M5, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The SX720 has one, while the E-M5 does not. While the built-in flash of the SX720 is not very powerful, it can at times be useful as a fill-in light.

Concerning the storage of imaging data, both the SX720 and the E-M5 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

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 PowerShot SX720 HS and Olympus OM-D E-M5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SX720 offers wifi support, while the E-M5 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the SX720 and the E-M5 have been discontinued, but can regularly be found used on ebay. The E-M5 was replaced by the Olympus E-M5 II, while the SX720 was followed by the Canon SX730. Further information on the features and operation of the SX720 and E-M5 can be found, respectively, in the Canon SX720 Manual (free pdf) or the online Olympus E-M5 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Canon SX720 or the Olympus E-M5 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Canon PowerShot SX720 HS:

• More detail: Offers more megapixels (20.2 vs 15.9MP) with a 13% higher linear resolution.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better video: Provides higher movie framerates (1080/60p versus 1080/60i).
• More detailed LCD: Has a higher resolution rear screen (922k vs 610k dots).
• Ready to shoot: Has a lens built-in, whereas the E-M5 requires a separate lens.
• More compact: Is smaller (110x64mm vs 122x89mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the E-M5).
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 4 years of technical progress since the E-M5 launch.

Arguments in favor of the Olympus OM-D E-M5:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
• Richer colors: The pixel size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• 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.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/3200s) to freeze action.
• Faster burst: Shoots at higher frequency (9 vs 5.9 flaps/sec) to capture the decisive moment.
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• Longer lasting: Gets more shots (360 versus 250) out of a single battery charge.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More heavily discounted: Has been around for much longer (launched in February 2012).

If the count of individual advantages (bullet points above) is taken as a guide, the E-M5 emerges as the winner of the match-up (15 : 12 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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 SX720 and the Olympus E-M5 place the cameras among the top in their class? Find out in the latest Best Superzoom 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 says little about, for example, the shooting experience and imaging performance of the SX720 and the E-M5 in practical situations. 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 where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major camera 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.

A score, therefore, has to be seen in close connection to the price and market introduction time 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
