Canon SX430 vs Ricoh GR III
The Canon PowerShot SX430 IS and the Ricoh GR III are two digital cameras that were announced, respectively, in January 2017 and February 2019. Both the SX430 and the GR III are fixed lens compact cameras that are based on a 1/2.3-inch (SX430) and an APS-C (GR III) sensor. The Canon has a resolution of 19.9 megapixels, whereas the Ricoh 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 SX430 IS and the Ricoh GR III? 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 SX430 and the Ricoh GR III. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures 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 Ricoh GR III is notably smaller (6 percent) than the Canon SX430. Moreover, the GR III is markedly lighter (20 percent) than the SX430. In this context, it is worth noting that neither the SX430 nor the GR III are weather-sealed.
The power pack in the GR III 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 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 markedly lower price (by 67 percent) than the GR III, which puts it into a different market segment. 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. 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 SX430 features a 1/2.3-inch sensor and the Ricoh GR III an APS-C sensor. The sensor area in the GR III is 1211 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.5. The sensor in the SX430 has a native 4:3 aspect ratio, while the one in the GR III offers a 3:2 aspect.
With 24MP, the GR III offers a higher resolution than the SX430 (19.9MP), but the GR III nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 1.19μm for the SX430) due to its larger sensor. Moreover, the GR III is a much more recent model (by 2 years and 1 month) than the SX430, 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 Ricoh GR III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GR III 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 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 GR III has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon PowerShot SX430 IS has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Ricoh GR III are ISO 100 to ISO 102400 (no boost).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 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 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 GR III provides a better video resolution than the SX430. It can shoot movie footage at 1080/60p, while the Canon is limited to 720/25p.
Apart from body and sensor, cameras can and do differ across a range of features. The SX430 and the GR III 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. That said, the GR III can be equipped with an optional viewfinder – the GV-1. The following table reports on some other key feature differences and similarities of the Canon SX430, the Ricoh GR III, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The SX430 has one, while the GR III 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 Ricoh GR III 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.
The SX430 is equipped with a zoom lens, while the GR III comes with a built-in prime. The SX430 has a 24-1080mm f/3.5-6.6 optic and the GR III offers a 28mm f/2.8 (focal lengths in full frame equivalent terms). Hence, the Canon provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the Ricoh. The GR III offers the faster maximum aperture.
Concerning the storage of imaging data, both the SX430 and the GR III write their files to SDXC cards. The GR III supports UHS-I cards (Ultra High Speed data transfer of up to 104 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 Ricoh GR III and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GR III has a hotshoe, which makes it possible to easily attach optional accessories, such as an external flash gun. The SX430 does not feature such an accessory-socket.
Both the SX430 and the GR III are recent models that are part of the current product line-up. The SX430 replaced the earlier Canon SX420, while the GR III followed on from the Ricoh GR II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Ricoh websites.
So how do things add up? Which of the two cameras – the Canon SX430 or the Ricoh GR III – 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 relative strengths (bullet points above) is taken as a measure, the GR III is the clear winner of the contest (20 : 5 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.

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 SX430 or the GR III 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.

Care should be taken when interpreting the review scores above, 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
