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 SX620 was somewhat cheaper (by 7 percent) than the SX420 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels 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.
While the two cameras under review share the same sensor size, the SX620 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 SX620 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). However, it should be noted that the SX620 is a somewhat more recent model (by 4 months) than the SX420, 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 Canon PowerShot SX420 IS has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Canon PowerShot SX620 HS are ISO 80 to ISO 3200 (no boost).
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 SX620 provides a better video resolution than the SX420. It can shoot movie footage at 1080/30p, while the SX420 is limited to 720/25p.
Apart from body and sensor, cameras can and do differ across a range of features. The SX420 and the SX620 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 table below summarizes some of the other core capabilities of the Canon SX420 and Canon SX620 in connection with corresponding information for a sample of similar cameras.

Both the SX420 and the SX620 have zoom lenses built in. The SX420 has a 24-1008mm f/3.5-6.6 optic and the SX620 offers a 25-625mm f/3.2-6.6 (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 SX620. The SX620 offers the faster maximum aperture.
Concerning the storage of imaging data, both the SX420 and the SX620 write their files to SDXC cards.
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 SX620 HS and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the SX420 and the SX620 are recent models that are part of the current product line-up. The SX420 replaced the earlier Canon SX410, while the SX620 followed on from the Canon SX610. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So what is the bottom line? Which of the two cameras – the Canon SX420 or the Canon SX620 – 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:
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) 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 heavily discounted: Has been on the market for longer (launched in January 2016).
Advantages of the Canon PowerShot SX620 HS:
- Better video: Provides higher definition movie capture (1080/30p vs 720/25p).
- More detailed LCD: Has a higher resolution rear screen (922k vs 230k dots).
- Faster burst: Shoots at higher frequency (2.5 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).
- More compact: Is smaller (97x57mm vs 104x69mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 143g or 44 percent) and is thus easier to take along.
- Longer lasting: Gets more shots (295 versus 195) out of a single battery charge.
- More modern: Was introduced somewhat (4 months) more recently.
If the count of relative strengths (bullet points above) is taken as a measure, the SX620 is the clear winner of the contest (8 : 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.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the SX420 and the SX620 in practical situations. 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.
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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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. Thus, a score needs to be put into the context of the launch date and the launch price 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.
