Canon RP vs SX620
The Canon EOS RP and the Canon PowerShot SX620 HS are two digital cameras that were revealed to the public, respectively, in February 2019 and May 2016. The Canon RP is a mirrorless interchangeable lens camera, while the SX620 is a fixed lens compact. The cameras are based on a full frame (Canon RP) and a 1/2.3-inch (SX620) sensor. The Canon RP has a resolution of 26.2 megapixels, whereas the SX620 provides 20.2 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS RP and the Canon PowerShot SX620 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.
The side-by-side display below illustrates the physical size and weight of the Canon RP and the Canon SX620. 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.
The SX620 can be obtained in three different colors (black, silver, red), while the Canon RP 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 Canon SX620 is considerably smaller (51 percent) than the Canon RP. In this context, it is worth noting that neither the Canon RP nor the SX620 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX620 has a lens built in, whereas the Canon RP is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.
Concerning battery life, the Canon RP gets 250 shots out of its LP-E17 battery, while the SX620 can take 295 images on a single charge of its NB-13L power pack. The power pack in the Canon RP can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The SX620 was launched at a lower price than the Canon RP, despite having a lens built in. 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 size of the imaging sensor is a crucial determinant 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon RP features a full frame sensor and the Canon SX620 a 1/2.3-inch sensor. The sensor area in the SX620 is 97 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 5.6. The sensor in the Canon RP has a native 3:2 aspect ratio, while the one in the SX620 offers a 4:3 aspect.
In terms of chip-set technology, the Canon RP uses a more advanced image processing engine (DIGIC 8) than the SX620 (DIGIC 4+), with benefits for noise reduction, color accuracy, and processing speed.
With 26.2MP, the Canon RP offers a higher resolution than the SX620 (20.2MP), but the Canon RP nevertheless has larger individual pixels (pixel pitch of 5.74μm versus 1.18μm for the SX620) due to its larger sensor. Moreover, the Canon RP is a much more recent model (by 2 years and 9 months) than the SX620, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the SX620 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Canon RP implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Canon RP for good quality output (200 dots per inch) amounts to 31.2 x 20.8 inches or 79.2 x 52.8 cm, for very good quality (250 dpi) 25 x 16.6 inches or 63.4 x 42.3 cm, and for excellent quality (300 dpi) 20.8 x 13.9 inches or 52.8 x 35.2 cm. The corresponding values for the Canon SX620 are 25.9 x 19.4 inches or 65.8 x 49.4 cm for good quality, 20.7 x 15.6 inches or 52.7 x 39.5 cm for very good quality, and 17.3 x 13 inches or 43.9 x 32.9 cm for excellent quality prints.
The Canon RP has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS RP has a native sensitivity range from ISO 100 to ISO 40000, which can be extended to ISO 50-102400. The corresponding ISO settings for the Canon PowerShot SX620 HS are ISO 80 to ISO 3200 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the Canon RP provides a higher video resolution than the SX620. It can shoot video footage at 4K/30p, while the SX620 is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the Canon RP has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the SX620 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon RP and Canon SX620 along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The Canon RP has a touchscreen, while the SX620 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The Canon RP has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the SX620 does not have a selfie-screen.
The Canon RP has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
Concerning the storage of imaging data, both the Canon RP and the SX620 write their files to SDXC cards. The Canon RP supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the SX620 cannot take advantage of Ultra High Speed SD 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 EOS RP and Canon PowerShot SX620 HS and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the Canon RP has a hotshoe, while the SX620 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Both the Canon RP and the SX620 are recent models that are part of the current product line-up. The SX620 replaced the earlier Canon SX610, while the Canon RP does not have a direct predecessor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.

If the count of individual advantages (bullet points above) is taken as a guide, the Canon RP is the clear winner of the match-up (25 : 10 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 remains incomplete and does no justice, for example, to the way the Canon RP or the SX620 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.
This is why expert reviews 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], 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.

|Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.|
The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
