Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX740 HS and the Sony Cyber-shot DSC-RX100 IV? 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

The physical size and weight of the Canon SX740 and the Sony RX100 IV 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 width, height and depth dimensions are rounded to the nearest millimeter.

The SX740 can be obtained in two different colors (black, silver), while the RX100 IV 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 RX100 IV is notably smaller (16 percent) than the Canon SX740. Moreover, the RX100 IV is slightly lighter (0 percent) than the SX740. In this context, it is worth noting that neither the SX740 nor the RX100 IV are weather-sealed.

Concerning battery life, the SX740 gets 265 shots out of its Canon NB-13L battery, while the RX100 IV can take 280 images on a single charge of its Sony NP-BX1 power pack. The battery packs of both cameras can be charged via USB, 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. 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.

The price is, of course, an important factor in any camera decision. 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 markedly lower price (by 60 percent) than the RX100 IV, 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 imaging sensor is a crucial determinant 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon SX740 features a 1/2.3-inch sensor and the Sony RX100 IV an one-inch sensor. The sensor area in the RX100 IV is 314 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 2.7. The sensor in the SX740 has a native 4:3 aspect ratio, while the one in the RX100 IV offers a 3:2 aspect.

Despite having a smaller sensor, the Canon SX740 offers a higher resolution of 20.2 megapixels, compared with 20 MP of the Sony RX100 IV. 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 2.41μm for the RX100 IV). However, it should be noted that the SX740 is much more recent (by 3 years and 1 month) than the RX100 IV, 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 Cyber-shot DSC-RX100 IV are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 80-25600.

Technology-wise, both cameras are equipped with BSI-CMOS (Backside Illuminated 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.

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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

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, and both provide the same movie specifications (4K/30p).

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the RX100 IV has an electronic viewfinder (2359k 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 adjacent table lists some of the other core features of the Canon SX740 and Sony RX100 IV along with similar information for a selection of comparators.

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

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 RX100 IV 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 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.

Both the SX740 and the RX100 IV have zoom lenses built in. The SX740 has a 24-960mm f/3.3-6.9 optic and the RX100 IV offers a 24-70mm f/1.8-2.8 (focal lengths in full frame equivalent terms). Hence, the Canon and Sony provide the same view at the wide-angle end, but the Sony has less tele-photo reach at the long end. The RX100 IV offers the faster maximum aperture.

The SX740 writes its imaging data to SDXC cards, while the RX100 IV uses SDXC or Memory Stick PRO Duo 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 SX740 HS and Sony Cyber-shot DSC-RX100 IV and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

The SX740 is a recent model that features in the current product line-up of Canon. In contrast, the RX100 IV has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the RX100 IV was succeeded by the Sony RX100 IV. Further information on the features and operation of the SX740 and RX100 IV can be found, respectively, in the Canon SX740 Manual (free pdf) or the online Sony RX100 IV Manual.

Review summary

So how do things add up? Is there a clear favorite between the Canon SX740 and the Sony RX100 IV? Which camera is better? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Canon PowerShot SX740 HS:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Faster shutter: Has higher mechanical shutter speed (1/3200s vs 1/2000s) to freeze action.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More affordable: Was introduced into a lower priced category (60 percent cheaper at launch).
• More modern: Reflects 3 years and 1 month of technical progress since the RX100 IV launch.

Advantages of the Sony Cyber-shot DSC-RX100 IV:

• 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 detailed LCD: Has a higher resolution rear screen (1228k vs 922k dots).
• Faster burst: Shoots at higher frequency (16 vs 10 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/3.3).
• More compact: Is smaller (102x58mm vs 110x64mm) and will fit more readily into a bag.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More heavily discounted: Has been around for much longer (launched in June 2015).

If the number of relative strengths (bullet points above) is taken as a guide, the RX100 IV 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 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 SX740 and the Sony RX100 IV place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Travel-Zoom 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the SX740 or the RX100 IV. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Expert reviews

This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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.
