Nikon D3100 vs Ricoh GR II
The Nikon D3100 and the Ricoh GR II are two digital cameras that were officially introduced, respectively, in August 2010 and June 2015. The D3100 is a DSLR, while the GR II is a fixed lens compact. Both cameras are equipped with an APS-C sensor. The Nikon has a resolution of 14.2 megapixels, whereas the Ricoh provides 16.1 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 Nikon D3100 and the Ricoh GR II? 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 physical size and weight of the Nikon D3100 and the Ricoh GR II 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 width, height and depth measures are rounded to the nearest millimeter.
The D3100 can be obtained in two different colors (black, red), while the GR II is only available in black.
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 (38 percent) than the Nikon D3100. In this context, it is worth noting that neither the D3100 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 built in, whereas the D3100 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the D3100 and their specifications in the Nikon Lens Catalog.
Concerning battery life, the D3100 gets 550 shots out of its EN-EL14 battery, while the GR II can take 320 images on a single charge of its DB65 power pack. The power pack in the GR II can be charged via the USB port, which can be very convenient when travelling.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will obviously take relative prices into account. 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. 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.
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. 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 are more costly to manufacture and tend to 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 4 percent bigger. They nevertheless have the same format factor of 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
With 16.1MP, the GR II offers a higher resolution than the D3100 (14.2MP), but the GR II has smaller individual pixels (pixel pitch of 4.79μm versus 5.01μm for the D3100). Yet, the GR II is a much more recent model (by 4 years and 9 months) than the D3100, and its sensor will have benefitted from technological advances during this time that 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.
The resolution advantage of the Ricoh GR II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GR II for good quality output (200 dots per inch) amounts to 24.6 x 16.3 inches or 62.6 x 41.5 cm, for very good quality (250 dpi) 19.7 x 13.1 inches or 50.1 x 33.2 cm, and for excellent quality (300 dpi) 16.4 x 10.9 inches or 41.7 x 27.6 cm. The corresponding values for the Nikon D3100 are 23 x 15.4 inches or 58.5 x 39 cm for good quality, 18.4 x 12.3 inches or 46.8 x 31.2 cm for very good quality, and 15.4 x 10.2 inches or 39 x 26 cm for excellent quality prints.
The Nikon D3100 has a native sensitivity range from ISO 100 to ISO 3200, which can be extended to ISO 100-12800. The corresponding ISO settings for the Ricoh GR II are ISO 100 to ISO 25600 (no boost).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under consideration, the GR II offers substantially better image quality than the D3100 (overall score 13 points higher). The advantage is based on 1.1 bits higher color depth, 2.4 EV in additional dynamic range, and 0.2 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.
|Ricoh GR II||APS-C||16.1||4928||3264||1080/30p||23.6||13.7||1078||80|
|Canon G7 X||1-inch||20.0||5472||3648||1080/60p||23.0||12.7||556||71|
|Panasonic GM5||Four Thirds||15.8||4592||3448||1080/60p||22.1||11.7||721||66|
|Sony RX100 III||1-inch||20.0||5472||3648||1080/60p||22.4||12.3||495||67|
Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the GR II provides a faster frame rate than the D3100. It can shoot movie footage at 1080/30p, while the Nikon is limited to 1080/24p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the D3100 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. That said, the GR II can be equipped with an optional viewfinder – the GV-1. The table below summarizes some of the other core capabilities of the Nikon D3100 and Ricoh GR II in connection with corresponding information for a sample of similar cameras.
|Ricoh GR II||optional||n||3.0||1230||fixed||n||1/4000s||4.0||Y||n|
|Canon G7 X||none||n||3.0||1040||tilting||Y||1/2000s||6.5||Y||Y|
|Sony RX100 III||1440||n||3.0||1229||tilting||n||1/2000s||10.0||Y||Y|
The Ricoh GR II 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.
Concerning the storage of imaging data, both the D3100 and the GR II write their files to SDXC cards. The GR II supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the D3100 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 Nikon D3100 and Ricoh GR II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.
| WiFi |
|Ricoh GR II||Y||stereo||mono||-||-||micro||2.0||Y||Y||-|
|Canon G7 X||-||stereo||mono||-||-||micro||2.0||Y||Y||-|
|Sony RX100 III||-||stereo||mono||-||-||micro||2.0||Y||Y||-|
It is notable that the GR II offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the D3100 does not provide wifi capability.
The GR II is a recent model that features in the current product line-up of Ricoh. In contrast, the D3100 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the D3100 was succeeded by the Nikon D3200. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon and Ricoh websites.
So how do things add up? Is there a clear favorite between the Nikon D3100 and the Ricoh GR II? Which camera is better? The listing below highlights the relative strengths of the two models.

If the count of individual advantages (bullet points above) is taken as a guide, the GR II is the clear winner of the contest (17 : 5 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 D3100 or the GR II perform in practice. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
