Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX70 HS and the Ricoh GR IIIx? 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.

Body comparison

The physical size and weight of the Canon SX70 and the Ricoh GR IIIx 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 size 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 Ricoh GR IIIx is considerably smaller (42 percent) than the Canon SX70. Moreover, the GR IIIx is substantially lighter (57 percent) than the SX70. In this context, it is worth noting that neither the SX70 nor the GR IIIx are weather-sealed.

Concerning battery life, the SX70 gets 325 shots out of its Canon LP-E12 battery, while the GR IIIx can take 200 images on a single charge of its Ricoh DB-110 power pack. The power pack in the GR IIIx 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 SX70 was launched at a markedly lower price (by 45 percent) than the GR IIIx, which puts it into a different market segment. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. 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.

Sensor comparison

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 generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels in a sensor of the same technological generation. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 SX70 features a 1/2.3-inch sensor and the Ricoh GR IIIx an APS-C sensor. The sensor area in the GR IIIx 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 SX70 has a native 4:3 aspect ratio, while the one in the GR IIIx offers a 3:2 aspect.

With 24MP, the GR IIIx offers a higher resolution than the SX70 (20.2MP), but the GR IIIx nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 1.18μm for the SX70) due to its larger sensor. Moreover, the GR IIIx is a much more recent model (by 2 years and 11 months) than the SX70, 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 IIIx implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GR IIIx 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 SX70 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 GR IIIx has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon PowerShot SX70 HS has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Ricoh GR IIIx are ISO 100 to ISO 102400 (no boost).

In terms of underlying technology, the SX70 is build around a BSI-CMOS sensor, while the GR IIIx uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

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 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. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the SX70 provides a higher video resolution than the GR IIIx. It can shoot video footage at 4K/30p, while the Ricoh is limited to 1080/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the SX70 has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GR IIIx relies on live view and the rear LCD for framing. That said, the GR IIIx can be equipped with an optional viewfinder – the GV-3. The table below summarizes some of the other core capabilities of the Canon SX70 and Ricoh GR IIIx in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The SX70 has one, while the GR IIIx does not. While the built-in flash of the SX70 is not very powerful, it can at times be useful as a fill-in light.

The Ricoh GR IIIx 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 SX70 is equipped with a zoom lens, while the GR IIIx comes with a built-in prime. The SX70 has a 21-1365mm f/3.4-6.5 optic and the GR IIIx offers a 40mm 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 IIIx offers the faster maximum aperture.

Concerning the storage of imaging data, both the SX70 and the GR IIIx write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

Connectivity comparison

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 SX70 HS and Ricoh GR IIIx and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SX70 has a microphone port, which is missing on the GR IIIx. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Both the SX70 and the GR IIIx are recent models that are part of the current product line-up. The SX70 replaced the earlier Canon SX60 , while the GR IIIx followed on from the Ricoh GR II. Further information on the features and operation of the SX70 and GR IIIx can be found, respectively, in the Canon SX70 Manual (free pdf) or the online Ricoh GR IIIx Manual.

If the count of individual advantages (bullet points above) is taken as a guide, the GR IIIx is the clear winner of the contest (17 : 11 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 SX70 and the Ricoh GR IIIx place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Prime Lens Compact 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the SX70 or the GR IIIx. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

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], digitalcameraworld [DCW], 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 ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
