Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX400 IS and the Canon PowerShot SX740 HS? 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 side-by-side display below illustrates the physical size and weight of the Canon SX400 and the Canon SX740. 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.

The SX740 can be obtained in two different colors (black, silver), while the SX400 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 Canon SX740 is somewhat smaller (2 percent) than the Canon SX400. Moreover, the SX740 is slightly lighter (4 percent) than the SX400. In this context, it is worth noting that neither the SX400 nor the SX740 are weather-sealed.

Concerning battery life, the SX400 gets 190 shots out of its Canon NB-11LH battery, while the SX740 can take 265 images on a single charge of its Canon NB-13L power pack. The power pack in the SX740 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. 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.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The SX400 was launched at a markedly lower price (by 38 percent) than the SX740, 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 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 more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature a 1/2.3-inch sensor and have a format factor (sometimes also referred to as "crop factor") of 5.6. Within the spectrum of camera sensors, this places the review cameras among the smaller-sensor digicams that favor affordability and compact design. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Technology-wise, the SX740 uses a more advanced image processing engine (DIGIC 8) than the SX400 (DIGIC 4+), with benefits for noise reduction, color accuracy, and processing speed.

While the two cameras under review share the same sensor size, the SX740 offers a higher resolution of 20.2 megapixels, compared with 15.9 MP of the SX400. This megapixels advantage translates into a 13 percent gain in linear resolution. On the other hand, these sensor specs imply that the SX740 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.18μm versus 1.33μm for the SX400). However, it should be noted that the SX740 is much more recent (by 4 years) than the SX400, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The resolution advantage of the Canon SX740 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SX740 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 Canon SX400 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 SX400 IS has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Canon PowerShot SX740 HS are ISO 100 to ISO 3200 (no boost).

In terms of underlying technology, the SX400 is build around a CCD sensor, while the SX740 uses a BSI-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 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"). 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the SX740 provides a better video resolution than the SX400. It can shoot movie footage at 4K/30p, while the SX400 is limited to 720/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The SX400 and the SX740 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. The table below summarizes some of the other core capabilities of the Canon SX400 and Canon SX740 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.

Both the SX400 and the SX740 have zoom lenses built in. The SX400 has a 24-720mm f/3.4-5.8 optic and the SX740 offers a 24-960mm f/3.3-6.9 (focal lengths in full frame equivalent terms). Hence, the SX400 and SX740 provide the same view at the wide-angle end, but the SX740 has more tele-photo reach at the long end. The SX740 offers the faster maximum aperture.

Concerning the storage of imaging data, both the SX400 and the SX740 write their files to SDXC cards. The SX740 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the SX400 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 SX400 IS and Canon PowerShot SX740 HS 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, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the SX400 does not provide wifi capability.

The SX740 is a recent model that features in the current product line-up of Canon. In contrast, the SX400 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the SX400 was succeeded by the Canon SX410. Further information on the features and operation of the SX400 and SX740 can be found, respectively, in the Canon SX400 Manual (free pdf) or the online Canon SX740 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Canon SX400 and the Canon SX740? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Canon PowerShot SX400 IS:

• More affordable: Was introduced into a lower priced category (38 percent cheaper at launch).
• More heavily discounted: Has been available for much longer (launched in July 2014).

Advantages of the Canon PowerShot SX740 HS:

• More detail: Has more megapixels (20.2 vs 15.9MP), which boosts linear resolution by 13%.
• Better jpgs: Has a more modern image processing engine (DIGIC 8 vs DIGIC 4+).
• Better video: Provides higher definition movie capture (4K/30p vs 720/30p).
• More detailed LCD: Has a higher resolution rear screen (922k vs 230k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster shutter: Has higher mechanical shutter speed (1/3200s vs 1/1600s) to freeze action.
• Faster burst: Shoots at higher frequency (10 vs 0.8 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Better light gathering: Has a lens with a wider maximum aperture (f/3.3 vs f/3.4).
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• Longer lasting: Gets more shots (265 versus 190) out of a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Reflects 4 years of technical progress since the SX400 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the SX740 is the clear winner of the contest (17 : 2 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 SX400 and the Canon SX740 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera listing whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the SX400 or the SX740. 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.

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, 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.
