Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G7X Mark III was somewhat cheaper (by 6 percent) than the GR at launch, but both cameras fall into the same price category. 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.

Sensor comparison

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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon G7 X Mark III features an one-inch sensor and the Ricoh GR an APS-C sensor. The sensor area in the GR is 219 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon G7 X Mark III and Ricoh GR sensor measures

Despite having a smaller sensor, the Canon G7 X Mark III offers a higher resolution of 20 megapixels, compared with 16.1 MP of the Ricoh GR. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 2.41μm versus 4.79μm for the GR). However, it should be noted that the G7X Mark III is much more recent (by 6 years and 2 months) than the GR, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the GR has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Canon G7 X Mark III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G7X Mark III for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Ricoh GR are 24.6 x 16.3 inches or 62.6 x 41.5 cm for good quality, 19.7 x 13.1 inches or 50.1 x 33.2 cm for very good quality, and 16.4 x 10.9 inches or 41.7 x 27.6 cm for excellent quality prints.

The Canon PowerShot G7 X Mark III has a native sensitivity range from ISO 125 to ISO 12800, which can be extended to ISO 125-25600. The corresponding ISO settings for the Ricoh GR are ISO 100 to ISO 25600 (no boost).

In terms of underlying technology, the G7X Mark III is build around a BSI-CMOS sensor, while the GR 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.

G7X Mark III versus GR MP

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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The G7X Mark III and the GR 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 can be equipped with an optional viewfinder – the GV-1. The adjacent table lists some of the other core features of the Canon G7 X Mark III and Ricoh GR 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 G7X Mark III has a touchscreen, while the GR has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The G7X Mark III 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 GR does not have a selfie-screen.

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 G7X Mark III 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 Canon G7 X Mark III and the Ricoh GR both have 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 G7X Mark III is equipped with a zoom lens, while the GR comes with a built-in prime. The G7X Mark III has a 24-100mm f/1.8-2.8 optic and the GR 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 G7X Mark III offers the faster maximum aperture.

Concerning the storage of imaging data, both the G7X Mark III and the GR 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.

It is notable that the G7X Mark III has a microphone port, which is missing on the GR. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

The G7X Mark III is a recent model that features in the current product line-up of Canon. In contrast, the GR has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the GR was succeeded by the Ricoh GR II. Further information on the features and operation of the G7X Mark III and GR can be found, respectively, in the Canon G7 X Mark III Manual (free pdf) or the online Ricoh GR Manual.

Review summary

So what is the bottom line? Is the Canon G7 X Mark III better than the Ricoh GR or vice versa? The listing below highlights the relative strengths of the two models.

ilogo

Advantages of the Canon PowerShot G7 X Mark III:

  • More detail: Offers more megapixels (20 vs 16.1MP) with a 11% higher linear resolution.
  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (30 vs 4 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/2.8).
  • Wider view: Has a wider-angle lens that facilitates landscape or interior shots.

ilogo

Arguments in favor of the Ricoh GR:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
  • More detailed LCD: Has a higher resolution rear screen (1230k vs 1040k dots).
  • Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
  • Less heavy: Has a lower weight (by 59g or 19 percent) and is thus easier to take along.
  • Longer lasting: Gets more shots (290 versus 235) out of a single battery charge.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • More heavily discounted: Has been around for much longer (launched in April 2013).

If the count of relative strengths (bullet points above) is taken as a measure, the G7X Mark III is the clear winner of the match-up (16 : 8 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.

G7X Mark III 16:08 GR

How about other alternatives? Do the specifications of the Canon G7 X Mark III and the Ricoh GR place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Prime Lens Compact Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G7X Mark III or the GR. 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 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 (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 review scores listed above should be treated 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 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.
