Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX510 HS and the Canon PowerShot SX540 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 SX510 and the Canon SX540. 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 Canon SX540 is notably larger (35 percent) than the Canon SX510. Moreover, the SX540 is markedly heavier (27 percent) than the SX510. In this context, it is worth noting that neither the SX510 nor the SX540 are weather-sealed.

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 SX510 was launched at a markedly lower price (by 38 percent) than the SX540, 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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.

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 SX540 uses a more advanced image processing engine (DIGIC 6) than the SX510 (DIGIC 4), with benefits for noise reduction, color accuracy, and processing speed.

While the two cameras under review share the same sensor size, the SX540 offers a higher resolution of 20.2 megapixels, compared with 15.9 MP of the SX510. This megapixels advantage translates into a 13 percent gain in linear resolution. On the other hand, these sensor specs imply that the SX540 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 SX510). However, it should be noted that the SX540 is much more recent (by 2 years and 4 months) than the SX510, 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 SX540 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SX540 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 SX510 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 SX510 HS has a native sensitivity range from ISO 80 to ISO 3200. The Canon PowerShot SX540 HS offers exactly the same ISO settings.

In terms of underlying technology, the SX510 is build around a CMOS sensor, while the SX540 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 assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. 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 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 SX540 provides a faster frame rate than the SX510. It can shoot movie footage at 1080/60p, while the SX510 is limited to 1080/24p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The SX510 and the SX540 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 adjacent table lists some of the other core features of the Canon SX510 and Canon SX540 along with similar information for a selection of comparators.

Both the SX510 and the SX540 have zoom lenses built in. The SX510 has a 24-720mm f/3.4-5.8 optic and the SX540 offers a 24-1200mm f/3.4-6.5 (focal lengths in full frame equivalent terms). Hence, the SX510 and SX540 provide the same view at the wide-angle end, but the SX540 has more tele-photo reach at the long end. Both cameras offer the same maximum aperture.

Concerning the storage of imaging data, both the SX510 and the SX540 write their files to SDXC cards. The SX540 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the SX510 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 SX510 HS and Canon PowerShot SX540 HS and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the SX510 and the SX540 have been discontinued, but can regularly be found used on ebay. The SX510 was replaced by the Canon SX520, while the SX540 does not have a direct successor. Further information on the features and operation of the SX510 and SX540 can be found, respectively, in the Canon SX510 Manual (free pdf) or the online Canon SX540 Manual.

Review summary

So how do things add up? Which of the two cameras – the Canon SX510 or the Canon SX540 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Canon PowerShot SX510 HS:

• More compact: Is smaller (104x70mm vs 120x82mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 93g or 21 percent) and hence easier to carry around.
• Longer lasting: Can take more shots (250 versus 205) on a single battery charge.
• 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 August 2013).

Arguments in favor of the Canon PowerShot SX540 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 6 vs DIGIC 4).
• Better video: Provides higher movie framerates (1080/60p versus 1080/24p).
• Faster shutter: Has higher mechanical shutter speed (1/2000s vs 1/1600s) to freeze action.
• Faster burst: Shoots at higher frequency (5.9 vs 3.8 flaps/sec) to capture the decisive moment.
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Reflects 2 years and 4 months of technical progress since the SX510 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the SX540 is the clear winner of the contest (9 : 5 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 SX510 and the Canon SX540 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 incomplete and does no justice, for example, to the way the SX510 or the SX540 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.

Expert reviews

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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
