Nikon D40 vs Ricoh GR III
The Nikon D40 and the Ricoh GR III are two digital cameras that were revealed to the public, respectively, in November 2006 and February 2019. The D40 is a DSLR, while the GR III is a fixed lens compact. Both cameras are equipped with an APS-C sensor. The Nikon has a resolution of 6 megapixels, whereas the Ricoh provides 24 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 D40 and the Ricoh GR III? 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 side-by-side display below illustrates the physical size and weight of the Nikon D40 and the Ricoh GR III. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures 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 III is considerably smaller (42 percent) than the Nikon D40. In this context, it is worth noting that neither the D40 nor the GR III are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the GR III has a lens built in, whereas the D40 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 D40 and their specifications in the Nikon Lens Catalog.
Concerning battery life, the D40 gets 470 shots out of its EN-EL9 battery, while the GR III can take 200 images on a single charge of its DB-110 power pack. The power pack in the GR III can be charged via the USB port, which can be very convenient when travelling.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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.
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. 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 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 III is 1 percent smaller. 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.
Despite having a slightly smaller sensor, the GR III offers a higher resolution of 24 megapixels, compared with 6 MP of the D40. 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 3.91μm versus 7.85μm for the D40). However, it should be noted that the GR III is much more recent (by 12 years and 3 months) than the D40, 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 III has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Ricoh GR III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GR III 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 Nikon D40 are 15 x 10 inches or 38.2 x 25.4 cm for good quality, 12 x 8 inches or 30.6 x 20.3 cm for very good quality, and 10 x 6.7 inches or 25.5 x 16.9 cm for excellent quality prints.
The GR III has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Nikon D40 has a native sensitivity range from ISO 200 to ISO 1600, which can be extended to ISO 200-3200. The corresponding ISO settings for the Ricoh GR III are ISO 100 to ISO 102400 (no boost).
In terms of underlying technology, the D40 is build around a CCD sensor, while the GR III 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 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"). 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. The GR III indeed provides for movie recording, while the D40 does not. The highest resolution format that the GR III can use is 1080/60p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the D40 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the GR III relies on live view and the rear LCD for framing. That said, the GR III can be equipped with an optional viewfinder – the GV-1. The table below summarizes some of the other core capabilities of the Nikon D40 and Ricoh GR III 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 D40 has one, while the GR III does not. While the built-in flash of the D40 is not very powerful, it can at times be useful as a fill-in light.
The Ricoh GR III 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 D40 writes its imaging data to SDHC cards, while the GR III uses SDXC cards. The GR III supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the D40 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 D40 and Ricoh GR III and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GR III offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the D40 does not provide wifi capability.
The GR III is a recent model that features in the current product line-up of Ricoh. In contrast, the D40 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the D40 was succeeded by the Nikon D40X. Further information on the features and operation of the D40 and GR III can be found, respectively, in the Nikon D40 Manual (free pdf) or the online Ricoh GR III Manual.
So what is the bottom line? Which of the two cameras – the Nikon D40 or the Ricoh GR III – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

If the number of relative strengths (bullet points above) is taken as a guide, the GR III is the clear winner of the contest (19 : 6 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 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.
How about other alternatives? Do the specifications of the Nikon D40 and the Ricoh GR III place the cameras among the top in their class? Find out in the latest Best DSLR 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the D40 and the GR III in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
