Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX50 HS and the Sony Alpha A7R? 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 SX50 and the Sony A7R 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 measures are rounded to the nearest millimeter.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A7R is notably larger (12 percent) than the Canon SX50. It is noteworthy in this context that the A7R is splash and dust-proof, while the SX50 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX50 has a lens built in, whereas the A7R 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 A7R and their specifications in the Sony FE Lens Catalog.

Concerning battery life, the SX50 gets 315 shots out of its Canon NB-10L battery, while the A7R can take 340 images on a single charge of its Sony NP-FW50 power pack. The power pack in the A7R can be charged via the USB port, which can be very convenient when travelling.

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

Any camera decision will obviously take relative prices into account. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The SX50 was launched at a lower price than the A7R, 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon SX50 features a 1/2.3-inch sensor and the Sony A7R a full frame sensor. The sensor area in the A7R is 2979 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.0. The sensor in the SX50 has a native 4:3 aspect ratio, while the one in the A7R offers a 3:2 aspect.

With 36.2MP, the A7R offers a higher resolution than the SX50 (12MP), but the A7R nevertheless has larger individual pixels (pixel pitch of 4.88μm versus 1.53μm for the SX50) due to its larger sensor. Moreover, the A7R is a somewhat more recent model (by 1 year) than the SX50, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the A7R has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Sony A7R implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7R for good quality output (200 dots per inch) amounts to 36.8 x 24.6 inches or 93.5 x 62.4 cm, for very good quality (250 dpi) 29.4 x 19.6 inches or 74.8 x 49.9 cm, and for excellent quality (300 dpi) 24.5 x 16.4 inches or 62.3 x 41.6 cm. The corresponding values for the Canon SX50 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.

The Canon PowerShot SX50 HS has a native sensitivity range from ISO 80 to ISO 6400. The corresponding ISO settings for the Sony Alpha A7R are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-51200.

In terms of underlying technology, the SX50 is build around a BSI-CMOS sensor, while the A7R 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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 consideration, the A7R offers substantially better image quality than the SX50 (overall score 48 points higher). The advantage is based on 5.3 bits higher color depth, 2.9 EV in additional dynamic range, and 3.9 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the A7R provides a faster frame rate than the SX50. It can shoot movie footage at 1080/60p, while the Canon is limited to 1080/24p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the A7R offers a substantially higher resolution than the one in the SX50 (2400k vs 202k dots). The following table reports on some other key feature differences and similarities of the Canon SX50, the Sony A7R, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The SX50 has one, while the A7R does not. While the built-in flash of the SX50 is not very powerful, it can at times be useful as a fill-in light.

The SX50 writes its imaging data to SDXC cards, while the A7R uses SDXC or Memory Stick PRO Duo cards. The A7R supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the SX50 cannot take advantage of Ultra High Speed SD cards.

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 SX50 HS and Sony Alpha A7R and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7R offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the SX50 does not provide wifi capability.

Both the SX50 and the A7R have been discontinued, but can regularly be found used on ebay. The SX50 was replaced by the Canon SX60, while the A7R was followed by the Sony A7R II. Further information on the features and operation of the SX50 and A7R can be found, respectively, in the Canon SX50 Manual (free pdf) or the online Sony A7R Manual.

Review summary

So what is the bottom line? Is the Canon SX50 better than the Sony A7R or vice versa? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Canon PowerShot SX50 HS:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Ready to shoot: Has a lens built-in, whereas the A7R requires a separate lens.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More heavily discounted: Has been on the market for longer (launched in September 2012).

Arguments in favor of the Sony Alpha A7R:

• More detail: Has more megapixels (36.2 vs 12MP), which boosts linear resolution by 77%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Scores substantially higher (48 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (5.3 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (2.9 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (3.9 stops ISO advantage).
• Better video: Provides higher movie framerates (1080/60p versus 1080/24p).
• Better sound: Can connect to an external microphone for higher quality sound recording.
• Better sound control: Has a headphone port that enables audio monitoring while recording.
• More detailed viewfinder: Has higher resolution electronic viewfinder (2400k vs 202k dots).
• More detailed LCD: Has a higher resolution rear screen (1230k vs 461k dots).
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/2000s) to freeze action.
• Faster burst: Shoots at higher frequency (4 vs 2.2 flaps/sec) to capture the decisive moment.
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• Easier travel charging: Can be conveniently charged via its USB port.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• 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.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Was introduced somewhat (1 year) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the A7R is the clear winner of the contest (20 : 8 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 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.

How about other alternatives? Do the specifications of the Canon SX50 and the Sony A7R 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the SX50 and the A7R 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 why expert reviews are important. 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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
