Canon SX50 vs Sony A58
The Canon PowerShot SX50 HS and the Sony Alpha SLT-A58 are two digital cameras that were officially introduced, respectively, in September 2012 and February 2013. The SX50 is a fixed lens compact, while the A58 is a DSLR. The cameras are based on a 1/2.3-inch (SX50) and an APS-C (A58) sensor. The Canon has a resolution of 12 megapixels, whereas the Sony provides 19.8 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 PowerShot SX50 HS and the Sony Alpha SLT-A58? 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.
An illustration of the physical size and weight of the Canon SX50 and the Sony A58 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A58 is notably larger (15 percent) than the Canon SX50. In this context, it is worth noting that neither the SX50 nor the A58 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX50 has a lens built in, whereas the A58 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 SX50 was launched at a lower price than the A58, 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.
The size of the imaging sensor is a crucial determinant 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. 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 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 A58 an APS-C sensor. The sensor area in the A58 is 1211 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.5. The sensor in the SX50 has a native 4:3 aspect ratio, while the one in the A58 offers a 3:2 aspect.
With 19.8MP, the A58 offers a higher resolution than the SX50 (12MP), but the A58 nevertheless has larger individual pixels (pixel pitch of 4.31μm versus 1.53μm for the SX50) due to its larger sensor. Moreover, the A58 is a somewhat more recent model (by 5 months) 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.
The resolution advantage of the Sony A58 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A58 for good quality output (200 dots per inch) amounts to 27.3 x 18.2 inches or 69.3 x 46.1 cm, for very good quality (250 dpi) 21.8 x 14.5 inches or 55.4 x 36.9 cm, and for excellent quality (300 dpi) 18.2 x 12.1 inches or 46.2 x 30.8 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 SLT-A58 are ISO 100 to ISO 16000, with the possibility to increase the ISO range to 100-25600.
For many cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under consideration, the A58 offers substantially better image quality than the SX50 (overall score 27 points higher). The advantage is based on 3 bits higher color depth, 1.3 EV in additional dynamic range, and 2.1 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.
|6.||Canon G1 X||1.5-inch||14.2||4352||3264||1080/24p||21.7||10.8||644||60|
|Note: DXO values in italics represent estimates based on sensor size and age.|
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 A58 provides a faster frame rate than the SX50. It can shoot movie footage at 1080/60i, while the Canon is limited to 1080/24p.
Apart from 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 A58 offers a substantially higher resolution than the one in the SX50 (1440k vs 202k dots). The adjacent table lists some of the other core features of the Canon SX50 and Sony A58 along with similar information for a selection of comparators.

It is notable that the A58 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The SX50 does not feature such a mic input.
Both the SX50 and the A58 have been discontinued, but can regularly be found used on eBay. The SX50 was replaced by the Canon SX60, while the A58 was followed by the Sony A68. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Sony websites.
So what is the bottom line? Is the Canon SX50 better than the Sony A58 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Canon PowerShot SX50 HS:
- Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
- 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: Comes with a built-in lens, while the A58 requires a separate lens.
- More compact: Is smaller (123x87mm vs 129x95mm) and thus needs less room in the bag.
- 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).
Advantages of the Sony Alpha SLT-A58:
- More detail: Has more megapixels (19.8 vs 12MP), which boosts linear resolution by 31%.
- Better image quality: Scores substantially higher (27 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (3 bits more color depth).

- Better low-light sensitivity: Can shoot in dim conditions (2.1 stops ISO advantage).
- Better video: Provides higher movie framerates (1080/60i versus 1080/24p).
- Better sound: Can connect to an external microphone for higher quality sound recording.
- More detailed viewfinder: Has higher resolution electronic viewfinder (1440k vs 202k dots).
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
- Faster burst: Shoots at higher frequency (5 vs 2.2 flaps/sec) to capture the decisive moment.
- More flexible: Makes it possible to change lenses and thus to use specialty optics.
- Longer lasting: Gets more shots (690 versus 315) out of a single battery charge.
- More modern: Was introduced somewhat (5 months) more recently.
If the number of relative strengths (bullet points above) is taken as a guide, the A58 is the clear winner of the contest (13 : 7 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 SX50 and the Sony A58 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best DSLR 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the SX50 or the A58. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is why hands-on reviews by experts 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.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, 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.
