Canon SX620 vs Sigma fp
The Canon PowerShot SX620 HS and the Sigma fp are two digital cameras that were revealed to the public, respectively, in May 2016 and July 2019. The SX620 is a fixed lens compact, while the fp is a mirrorless interchangeable lens camera. The cameras are based on a 1/2.3-inch (SX620) and a full frame (fp) sensor. The Canon has a resolution of 20.2 megapixels, whereas the Sigma provides 24 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 PowerShot SX620 HS and the Sigma fp? 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 physical size and weight of the Canon SX620 and the Sigma fp are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.
The SX620 can be obtained in three different colors (black, silver, red), while the fp 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 Sigma fp is considerably larger (43 percent) than the Canon SX620. It is noteworthy in this context that the fp is splash and dust-proof, while the SX620 does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX620 has a lens built in, whereas the fp is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.
The power pack in the fp can be charged via the USB port, which can be very convenient when travelling.

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 launched at a lower price than the fp, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
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. 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon SX620 features a 1/2.3-inch sensor and the Sigma fp a full frame sensor. The sensor area in the fp is 2964 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.0. The sensor in the SX620 has a native 4:3 aspect ratio, while the one in the fp offers a 3:2 aspect.
With 24MP, the fp offers a higher resolution than the SX620 (20.2MP), but the fp nevertheless has larger individual pixels (pixel pitch of 5.98μm versus 1.18μm for the SX620) due to its larger sensor. Moreover, the fp is a much more recent model (by 3 years and 2 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 pixel-units. 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 Sigma fp implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the fp for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 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 PowerShot SX620 HS has a native sensitivity range from ISO 80 to ISO 3200. The corresponding ISO settings for the Sigma fp are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 6-102400.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the fp provides a better video resolution than the SX620. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. The SX620 and the fp 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 adjacent table lists some of the other core features of the Canon SX620 and Sigma fp along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The SX620 has one, while the fp does not. While the built-in flash of the SX620 is not very powerful, it can at times be useful as a fill-in light.
The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the fp is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The Sigma fp 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 SX620 and the fp write their files to SDXC cards. The fp 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 PowerShot SX620 HS and Sigma fp and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.
| WiFi |
|Canon G9 X Mark II||-||stereo||mono||-||-||micro||2.0||Y||Y||Y|
|Canon G7 X Mark II||-||stereo||mono||-||-||micro||2.0||Y||Y||-|
|Canon G5 X||Y||stereo||mono||-||-||mini||2.0||Y||Y||-|
|Canon G9 X||-||stereo||mono||-||-||micro||2.0||Y||Y||-|
It is notable that the SX620 offers wifi support, while the fp does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the SX620 and the fp are recent models that are part of the current product line-up. The SX620 replaced the earlier Canon SX610, while the fp 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 and Sigma websites.
So how do things add up? Is there a clear favorite between the Canon SX620 and the Sigma fp? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Canon PowerShot SX620 HS:
- Ready to shoot: Has a lens built-in, whereas the fp requires a separate lens.
- More compact: Is smaller (97x57mm vs 113x70mm) and thus needs less room in the bag.
- Less heavy: Is lighter even though it comes with a built-in lens (unlike the fp).

- Faster buffer clearing: Has an SD card interface that supports the UHS-II standard.
- More modern: Reflects 3 years and 2 months of technical progress since the SX620 launch.
If the count of individual advantages (bullet points above) is taken as a guide, the fp is the clear winner of the contest (20 : 9 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. 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 SX620 and the Sigma fp place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Mirrorless Interchangeable Lens Camera listings 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 SX620 or the fp 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.
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 (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.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
