Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX420 IS and the Canon PowerShot SX700 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 SX420 and the Canon SX700. 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.

Both cameras are available in two different colors (black, red).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon SX700 is somewhat larger (4 percent) than the Canon SX420. However, the SX700 is markedly lighter (17 percent) than the SX420. In this context, it is worth noting that neither the SX420 nor the SX700 are weather-sealed.

Concerning battery life, the SX420 gets 195 shots out of its Canon NB-11LH battery, while the SX700 can take 250 images on a single charge of its Canon NB-6LH power pack.

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.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The SX420 was launched at a somewhat lower price (by 14 percent) than the SX700, which makes it more attractive for photographers on a tight budget. 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. 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 are more costly to manufacture and tend to 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 SX700 uses a more advanced image processing engine (DIGIC 6) than the SX420 (DIGIC 4+), with benefits for noise reduction, color accuracy, and processing speed.

While the two cameras under review share the same sensor size, the SX420 offers a higher resolution of 19.9 megapixels, compared with 15.9 MP of the SX700. This megapixels advantage translates into a 12 percent gain in linear resolution. On the other hand, these sensor specs imply that the SX420 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.19μm versus 1.33μm for the SX700). In this context, it should be noted, however, that the SX420 is a somewhat more recent model (by 1 year and 10 months) than the SX700, and its sensor might have benefitted from technological advances during this time that at least partly 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 SX420 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SX420 for good quality output (200 dots per inch) amounts to 25.8 x 19.3 inches or 65.4 x 49.1 cm, for very good quality (250 dpi) 20.6 x 15.5 inches or 52.3 x 39.3 cm, and for excellent quality (300 dpi) 17.2 x 12.9 inches or 43.6 x 32.7 cm. The corresponding values for the Canon SX700 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 SX420 IS has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Canon PowerShot SX700 HS are ISO 100 to ISO 3200 (no boost).

In terms of underlying technology, the SX420 is build around a CCD sensor, while the SX700 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 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 also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the SX700 provides a better video resolution than the SX420. It can shoot movie footage at 1080/60p, while the SX420 is limited to 720/25p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The SX420 and the SX700 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 following table reports on some other key feature differences and similarities of the Canon SX420, the Canon SX700, and comparable cameras.

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

Both the SX420 and the SX700 have zoom lenses built in. The SX420 has a 24-1008mm f/3.5-6.6 optic and the SX700 offers a 25-750mm f/3.2-6.9 (focal lengths in full frame equivalent terms). Hence, the SX420 provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the SX700. The SX700 offers the faster maximum aperture.

Concerning the storage of imaging data, both the SX420 and the SX700 write their files to SDXC 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 SX420 IS and Canon PowerShot SX700 HS and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the SX420 and the SX700 have been discontinued, but can regularly be found used on ebay. The SX700 was replaced by the Canon SX710, while the SX420 was followed by the Canon SX430. Further information on the features and operation of the SX420 and SX700 can be found, respectively, in the Canon SX420 Manual (free pdf) or the online Canon SX700 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Canon SX420 or the Canon SX700 – 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.

Reasons to prefer the Canon PowerShot SX420 IS:

• More detail: Offers more megapixels (19.9 vs 15.9MP) with a 12% higher linear resolution.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/3200s) to freeze action.
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• More affordable: Was introduced into a lower priced segment (14 percent cheaper at launch).
• More modern: Is somewhat more recent (announced 1 year and 10 months after the SX700).

Arguments in favor of the Canon PowerShot SX700 HS:

• Better jpgs: Has a more modern image processing engine (DIGIC 6 vs DIGIC 4+).
• Better video: Provides higher definition movie capture (1080/60p vs 720/25p).
• More detailed LCD: Has a higher resolution rear screen (922k vs 230k dots).
• Faster burst: Shoots at higher frequency (8.5 vs 0.5 flaps/sec) to capture the decisive moment.
• Better light gathering: Has a lens with a wider maximum aperture (f/3.2 vs f/3.5).
• Less heavy: Has a lower weight (by 56g or 17 percent) and is thus easier to take along.
• Longer lasting: Gets more shots (250 versus 195) out of a single battery charge.
• More heavily discounted: Has been on the market for longer (launched in February 2014).

If the number of relative strengths (bullet points above) is taken as a guide, the SX700 emerges as the winner of the match-up (8 : 6 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 SX420 and the Canon SX700 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 SX420 or the SX700. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
