Canon 100D versus Ricoh GR II
The Canon EOS 100D (called Canon SL1 in some regions) and the Ricoh GR II are two digital cameras that were officially introduced, respectively, in March 2013 and June 2015. The 100D is a DSLR, while the GR II is a fixed lens compact. Both cameras are equipped with an APS-C sensor. The Canon has a resolution of 17.9 megapixel, whereas the Ricoh provides 16.1 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.
Body comparison: Canon 100D vs Ricoh GR II
The side-by-side display below illustrates the physical size and weight of the Canon 100D and the Ricoh GR II. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the 100D – represents the basis or 100 percent across all the size and weight measures).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Ricoh GR II is considerably smaller (31 percent) than the Canon 100D. In this context, it is worth noting that neither the 100D nor the GR II are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the GR II has a lens build in, whereas the 100D is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can find an overview of optics for the 100D and their specifications in the Canon EF Lens Catalog.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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: Canon 100D vs Ricoh GR II
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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.
Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the GR II is 11 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (100D) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Despite having a smaller sensor, the Canon 100D offers a higher resolution of 17.9 megapixel, compared with 16.1 MP of the Ricoh 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 4.31μm versus 4.79μm for the GR II). Moreover, it should be noted that the GR II is much more recent (by 2 years and 2 months) than the 100D, 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 the GR II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
For most cameras, data on sensor performance has been reported by DXO Mark. 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. Of the two cameras under consideration, the GR II offers substantially better image quality than the 100D (overall score 17 points higher). The advantage is based on 1.8 bits higher color depth, 2.4 EV in additional dynamic range, and 0.4 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

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, and both provide the same movie specifications (1080/30p).
Feature comparison: Canon 100D vs Ricoh GR II
Apart from body and sensor, cameras can and do differ across a range of features. For example, the 100D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the GR II relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon 100D and Ricoh GR II in connection with corresponding information for a sample of similar cameras.

If the number of relative strengths (bullet points above) is taken as a guide, the GR II emerges as the winner of the match-up (10 : 8 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.
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 100D or the GR II 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 above review scores should be interpreted with care, though. The ratings are only valid when refering to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, 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.
