Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX30 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

An illustration of the physical size and weight of the Canon SX30 and the Canon SX740 is provided 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 SX30 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 considerably smaller (38 percent) than the Canon SX30. Moreover, the SX740 is substantially lighter (50 percent) than the SX30. In this context, it is worth noting that neither the SX30 nor the SX740 are weather-sealed.

Concerning battery life, the SX30 gets 370 shots out of its Canon NB-7L 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. 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.

Any camera decision will obviously take relative prices into account. 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 SX740 was somewhat cheaper (by 7 percent) than the SX30 at launch, but both cameras fall into the same price category. 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.

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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies 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 SX30 (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 14 MP of the SX30. This megapixels advantage translates into a 20 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 1.41μm for the SX30). However, it should be noted that the SX740 is much more recent (by 7 years and 10 months) than the SX30, 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 SX30 are 21.6 x 16.2 inches or 54.9 x 41.1 cm for good quality, 17.3 x 13 inches or 43.9 x 32.9 cm for very good quality, and 14.4 x 10.8 inches or 36.6 x 27.4 cm for excellent quality prints.

The Canon PowerShot SX30 IS has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-6400. The corresponding ISO settings for the Canon PowerShot SX740 HS are ISO 100 to ISO 3200 (no boost).

In terms of underlying technology, the SX30 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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

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, but the SX740 provides a better video resolution than the SX30. It can shoot movie footage at 4K/30p, while the SX30 is limited to 720/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the SX30 has an electronic viewfinder (202k 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 SX30 and Canon SX740 along with similar information for a selection of comparators.

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 SX30 and the SX740 have zoom lenses built in. The SX30 has a 24-840mm f/2.7-5.8 optic and the SX740 offers a 24-960mm f/3.3-6.9 (focal lengths in full frame equivalent terms). Hence, the SX30 and SX740 provide the same view at the wide-angle end, but the SX740 has more tele-photo reach at the long end. The SX30 offers the faster maximum aperture.

Concerning the storage of imaging data, both the SX30 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 SX30 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 SX30 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 SX30 has a hotshoe, while the SX740 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

The SX740 is a recent model that features in the current product line-up of Canon. In contrast, the SX30 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the SX30 was succeeded by the Canon SX40. Further information on the features and operation of the SX30 and SX740 can be found, respectively, in the Canon SX30 Manual (free pdf) or the online Canon SX740 Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Canon SX30 or the Canon SX740 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Canon PowerShot SX30 IS:

• Easier framing: Has an electronic viewfinder for image composition and settings control.
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• Better light gathering: Has a lens with a wider maximum aperture (f/2.7 vs f/3.3).
• Longer lasting: Can take more shots (370 versus 265) on a single battery charge.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More heavily discounted: Has been available for much longer (launched in September 2010).

Arguments in favor of the Canon PowerShot SX740 HS:

• More detail: Has more megapixels (20.2 vs 14MP), which boosts linear resolution by 20%.
• 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).
• Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (922k vs 230k dots).
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (10 vs 0.6 flaps/sec) to capture the decisive moment.
• 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.
• More compact: Is smaller (110x64mm vs 123x92mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 302g or 50 percent) and is thus easier to take along.
• 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 7 years and 10 months of technical progress since the SX30 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the SX740 is the clear winner of the contest (16 : 6 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 SX30 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 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 SX30 or the SX740. 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 expert reviews are important. 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.

Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
