The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Canon SX420 was launched in the US market at a price of $299. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison with a 35mm slide

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 more expensive and lead to bigger and heavier cameras and lenses.

The Canon SX420 features a 1/2.3-inch sensor and has a format factor (sometimes also referred to as "crop factor") of 5.6. Within the spectrum of camera sensors, this places the Canon SX420 among the smaller-sensor digicams that favor affordability and compact design.

Consistent information on actual sensor performance is available from DXO Mark for most cameras. 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 alternatives.

Many modern cameras cannot only take still pictures, but also record videos. The SX420 indeed provides movie recording capabilities. The highest resolution format that the SX420 can use is 720/25p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The adjacent tables list some of the other core features of the Canon SX420 along with similar information for a selection of comparators.

One convenient feature of the SX420 is the presence of an on-board flash. While this built-in flash is not very powerful, it can at times be useful as a fill-in light to brighten deep shadow areas.

Connection 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, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SX420 offers wifi support. Wifi can be a very convenient means to transfer image data to an off-camera location.

The SX420 has a zoom lens built in (4.3-180.6mm f/3.5-6.6), which, in full frame equivalent terms, provides a focal length range from 24 to 1008mm. The camera is, hence, ready to shoot, while remaining more compact in size than an interchangeable lens camera with an optic that offers similar focal length and aperture specifications.

Further information on the features and operation of the SX420 can be found in the free online Canon SX420 Manual or on the Canon support site.

Expert reviews

While the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the SX420 in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is why expert reviews are important. The table below summarizes the assessments of some of the best known camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]).

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. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
