Canon SX430 vs Leica S3
The Canon PowerShot SX430 IS and the Leica S3 are two digital cameras that were revealed to the public, respectively, in January 2017 and September 2018. The SX430 is a fixed lens compact, while the S3 is a DSLR. The cameras are based on a 1/2.3-inch (SX430) and a medium format (S3) sensor. The Canon has a resolution of 19.9 megapixels, whereas the Leica provides 64 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 SX430 IS and the Leica S3? 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 SX430 and the Leica S3 are illustrated 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 dimensions are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Leica S3 is considerably larger (168 percent) than the Canon SX430. It is noteworthy in this context that the S3 is splash and dust-proof, while the SX430 does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX430 has a lens built in, whereas the S3 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Any camera decision will naturally be influenced heavily by the price. 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 SX430 was launched at a lower price than the S3, 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon SX430 features a 1/2.3-inch sensor and the Leica S3 a medium format sensor. The sensor area in the S3 is 4721 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 0.8. The sensor in the SX430 has a native 4:3 aspect ratio, while the one in the S3 offers a 3:2 aspect.
With 64MP, the S3 offers a higher resolution than the SX430 (19.9MP), but the S3 nevertheless has larger individual pixels (pixel pitch of 4.59μm versus 1.19μm for the SX430) due to its larger sensor. Moreover, the S3 is a somewhat more recent model (by 1 year and 8 months) than the SX430, and its sensor might 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 Leica S3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the S3 for good quality output (200 dots per inch) amounts to 49 x 32.7 inches or 124.5 x 83 cm, for very good quality (250 dpi) 39.2 x 26.1 inches or 99.6 x 66.4 cm, and for excellent quality (300 dpi) 32.7 x 21.8 inches or 83 x 55.3 cm. The corresponding values for the Canon SX430 are 25.8 x 19.3 inches or 65.4 x 49.1 cm for good quality, 20.6 x 15.5 inches or 52.3 x 39.3 cm for very good quality, and 17.2 x 12.9 inches or 43.6 x 32.7 cm for excellent quality prints.
The Canon PowerShot SX430 IS has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Leica S3 are ISO 100 to ISO 50000 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many 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 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 also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the S3 provides a better video resolution than the SX430. It can shoot movie footage at 4K/24p, while the Canon is limited to 720/25p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the S3 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the SX430 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Canon SX430, the Leica S3, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The SX430 has one, while the S3 does not. While the built-in flash of the SX430 is not very powerful, it can at times be useful as a fill-in light.
The SX430 writes its imaging data to SDXC cards, while the S3 uses Compact Flash or SDXC cards. The S3 features dual card slots, which can be very useful in case a memory card fails. In contrast, the SX430 only has one slot. The S3 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the SX430 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 SX430 IS and Leica S3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the S3 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The SX430 does not feature such a mic input.
Studio photographers will appreciate that the Leica S3 (unlike the SX430) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Travel and landscape photographers will find it useful that the S3 has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.
Both the SX430 and the S3 are recent models that are part of the current product line-up. The SX430 replaced the earlier Canon SX420, while the S3 followed on from the Leica S Typ 007. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Leica websites.
So what conclusions can be drawn? Which of the two cameras – the Canon SX430 or the Leica S3 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

If the count of individual advantages (bullet points above) is taken as a guide, the S3 is the clear winner of the contest (22 : 8 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the SX430 or the S3. 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 adjacent summary-table relays the overall verdicts of several of the most popular 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.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
