Ricoh GR II versus Canon G7 X

The Ricoh GR II and the Canon PowerShot G7 X are two digital cameras that were announced, respectively, in June 2015 and September 2014. Both the GR II and the G7X are fixed lens compact cameras that are based on an APS-C (GR II) and an one-inch (G7X) sensor. The Ricoh has a resolution of 16.1 megapixel, whereas the Canon provides 20 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The two cameras under review were launched at the same price and fall into the same 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Ricoh GR II vs Canon G7 X

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. 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Ricoh GR II features an APS-C sensor and the Canon G7 X an one-inch sensor. The sensor area in the G7X is 69 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Ricoh GR II and Canon G7 X sensor measures

Despite having a smaller sensor, the G7X offers a higher resolution of 20 megapixel, compared with 16.1 MP of the GR II. This megapixel 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 II). Moreover, it should be noted that the GR II is a somewhat more recent model (by 9 months) than the G7X, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the GR II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

GR II versus G7X 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"). Of the two cameras under review, the GR II has a notably higher overall DXO score than the G7X (overall score 9 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.6 bits higher color depth, 1 EV in additional dynamic range, and 1 stops in additional low light sensitivity. 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 cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the G7X provides a faster frame rate than the GR II. It can shoot movie footage at 1080/60p, while the Ricoh is limited to 1080/30p.

 

Feature comparison: Ricoh GR II vs Canon G7 X

Beyond body and sensor, cameras can and do differ across a range of features. The GR II and the G7X 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 II can be equipped with an optional viewfinder – the GV-1. The following table reports on some other key feature differences and similarities of the Ricoh GR II, the Canon G7 X, and comparable cameras.

The G7X is equipped with a zoom lens, while the GR II comes with a build-in prime. The G7X has a 24-100mm f/1.8-2.8 optic and the GR II 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 offers the faster maximum aperture.

Both the GR II and the G7X have been discontinued, but can regularly be found used on eBay. The G7X was replaced by the Canon G7 X Mark II, while the GR II was followed by the ...

  • Longer lasting: Can take more shots (320 versus 210) on a single battery charge.
  • More modern: Is somewhat more recent (announced 9 months after the G7X).

ilogo

Arguments in favor of the Canon PowerShot G7 X:

  • More detail: Has more megapixels (20 vs 16.1MP), which boosts linear resolution by 11%.
  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster burst: Shoots at higher frequency (6.5 vs 4 flaps/sec) to capture the decisive moment.
  • 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.
  • More compact: Is smaller (103x60mm vs 117x63mm) and will fit more readily into a bag.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More heavily discounted: Has been on the market for longer (launched in September 2014).

If the count of relative strengths (bullet points above) is taken as a measure, the G7X comes out slightly ahead of the GR II (11 : 10 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.

GR II 10:11 G7X

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 GR II or the G7X handle or 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 hands-on reviews by experts are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
