Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX420 IS and the Sony Cyber-shot DSC-HX400V? 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 SX420 and the Sony HX400V is provided in the side-by-side display below. 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 SX420 can be obtained in two different colors (black, red), while the HX400V 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 HX400V is considerably larger (68 percent) than the Canon SX420. Moreover, the HX400V is substantially heavier (103 percent) than the SX420. In this context, it is worth noting that neither the SX420 nor the HX400V are weather-sealed.

Concerning battery life, the SX420 gets 195 shots out of its Canon NB-11LH battery, while the HX400V can take 300 images on a single charge of its Sony NP-BX1 power pack.

Any camera decision will obviously take relative prices into account. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The SX420 was launched at a markedly lower price (by 40 percent) than the HX400V, 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 sensor inside a digital camera is one of the key determinants 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 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.

While the two cameras under review share the same sensor size, the HX400V offers a slightly higher resolution of 20.2 megapixels, compared with 19.9 MP of the SX420. This megapixels advantage translates into a 0.59999999999999 percent gain in linear resolution. On the other hand, these sensor specs imply that the HX400V has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.18μm versus 1.19μm for the SX420). Moreover, it should be noted, that the SX420 is a somewhat more recent model (by 1 year and 10 months) than the HX400V, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels. 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 Canon PowerShot SX420 IS has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Sony Cyber-shot DSC-HX400V are ISO 80 to ISO 3200, with the possibility to increase the ISO range to 80-12800.

In terms of underlying technology, the SX420 is build around a CCD sensor, while the HX400V 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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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 have a sensor with sufficiently fast read-out times for moving pictures, but the HX400V provides a better video resolution than the SX420. It can shoot movie footage at 1080/60p, while the Canon is limited to 720/25p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the HX400V has an electronic viewfinder (210k dots), which can be very helpful when shooting in bright sunlight. In contrast, the SX420 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon SX420 and Sony HX400V in connection with corresponding information for a sample of similar cameras.

Both the SX420 and the HX400V have zoom lenses built in. The SX420 has a 24-1008mm f/3.5-6.6 optic and the HX400V offers a 24-1200mm f/2.8-6.3 (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 more tele-photo reach at the long end. The HX400V offers the faster maximum aperture.

The SX420 writes its imaging data to SDXC cards, while the HX400V uses SDXC or Memory Stick PRO Duo 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 Sony Cyber-shot DSC-HX400V and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the HX400V has a hotshoe, which makes it possible to easily attach optional accessories, such as an external flash gun. The SX420 does not feature such an accessory-socket.

Travel and landscape photographers will find it useful that the HX400V has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the SX420 and the HX400V have been discontinued, but can regularly be found used on ebay. The SX420 was replaced by the Canon SX430, while the HX400V does not have a direct successor. Further information on the features and operation of the SX420 and HX400V can be found, respectively, in the Canon SX420 Manual (free pdf) or the online Sony HX400V Manual.

Review summary

So what conclusions can be drawn? Is the Canon SX420 better than the Sony HX400V or vice versa? The listing below highlights the relative strengths of the two models.

Advantages of the Canon PowerShot SX420 IS:

• More compact: Is smaller (104x69mm vs 130x93mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 335g or 51 percent) and hence easier to carry around.
• More affordable: Was introduced into a lower priced category (40 percent cheaper at launch).
• More modern: Is somewhat more recent (announced 1 year and 10 months after the HX400V).

Reasons to prefer the Sony Cyber-shot DSC-HX400V:

• Better video: Provides higher definition movie capture (1080/60p vs 720/25p).
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• More detailed LCD: Has a higher resolution rear screen (921k vs 230k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Faster burst: Shoots at higher frequency (10 vs 0.5 flaps/sec) to capture the decisive moment.
• Better light gathering: Has a lens with a wider maximum aperture (f/2.8 vs f/3.5).
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• Longer lasting: Gets more shots (300 versus 195) out of a single battery charge.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• Easier geotagging: Features an internal GPS sensor to log localization data.
• 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 HX400V is the clear winner of the contest (11 : 4 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 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 SX420 and the Sony HX400V 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 incomplete and does no justice, for example, to the way the SX420 or the HX400V perform in practice. 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 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 assessments were made in relation to similar cameras of the same technological generation. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
