Canon SX740 vs Sony A58
The Canon PowerShot SX740 HS and the Sony Alpha SLT-A58 are two digital cameras that were officially introduced, respectively, in July 2018 and February 2013. The SX740 is a fixed lens compact, while the A58 is a DSLR. The cameras are based on a 1/2.3-inch (SX740) and an APS-C (A58) sensor. The Canon has a resolution of 20.2 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 SX740 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.
The physical size and weight of the Canon SX740 and the Sony A58 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.
The SX740 can be obtained in two different colors (black, silver), while the A58 is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A58 is considerably larger (74 percent) than the Canon SX740. In this context, it is worth noting that neither the SX740 nor the A58 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX740 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.
Concerning battery life, the SX740 gets 265 shots out of its NB-13L battery, while the A58 can take 690 images on a single charge of its NP-FM500H power pack. The power pack in the SX740 can be charged via the USB port, so that it is not always necessary to take the battery charger along 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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The SX740 was launched at a lower price than the A58, despite having a lens built in. 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.
The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 SX740 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 SX740 has a native 4:3 aspect ratio, while the one in the A58 offers a 3:2 aspect.
Despite having a smaller sensor, the Canon SX740 offers a higher resolution of 20.2 megapixels, compared with 19.8 MP of the Sony A58. 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 4.31μm for the A58). However, it should be noted that the SX740 is much more recent (by 5 years and 5 months) than the A58, 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 SX740 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The Canon PowerShot SX740 HS has a native sensitivity range from ISO 100 to ISO 3200. 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.
In terms of underlying technology, the SX740 is build around a BSI-CMOS sensor, while the A58 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.
|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 have a sensor with sufficiently fast read-out times for moving pictures, but the SX740 provides a higher video resolution than the A58. It can shoot video footage at 4K/30p, while the Sony is limited to 1080/60i.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the A58 has an electronic viewfinder (1440k dots), which can be very helpful when shooting in bright sunlight. In contrast, the SX740 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon SX740 and Sony A58 in connection with corresponding information for a sample of similar cameras.

The Canon SX740 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 SX740 writes its imaging data to SDXC cards, while the A58 uses SDXC or Memory Stick PRO Duo cards. The SX740 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the A58 cannot take advantage of Ultra High Speed SD cards.
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 SX740 HS and Sony Alpha SLT-A58 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SX740 offers wifi support, while the A58 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
The SX740 is a recent model that features in the current product line-up of Canon. In contrast, the A58 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the A58 was succeeded 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 how do things add up? Is the Canon SX740 better than the Sony A58 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Canon PowerShot SX740 HS:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.

If the count of individual advantages (bullet points above) is taken as a guide, the SX740 is the clear winner of the match-up (16 : 12 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 SX740 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 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 SX740 or the A58 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.
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.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
