Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D2H and the Ricoh GR? 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.

Body comparison

An illustration of the physical size and weight of the Nikon D2H and the Ricoh GR is provided 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.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Ricoh GR is considerably smaller (70 percent) than the Nikon D2H. It is worth mentioning in this context that the D2H is splash and dust resistant, while the GR does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the GR has a lens built in, whereas the D2H 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 D2H and their specifications in the Nikon Lens Catalog.

Concerning battery life, the D2H gets 2900 shots out of its Nikon EN-EL4a battery, while the GR can take 290 images on a single charge of its Ricoh DB-65 power pack. As can be seen in the images above, the D2H has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. The power pack in the GR 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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The GR was launched at a lower price than the D2H, despite having a lens built in. 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 is 2 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.

With 16.1MP, the GR offers a higher resolution than the D2H (4MP), but the GR has smaller individual pixels (pixel pitch of 4.79μm versus 9.50μm for the D2H). Yet, the GR is a much more recent model (by 9 years and 8 months) than the D2H, 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 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Ricoh GR implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GR 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 D2H are 12.3 x 8.2 inches or 31.3 x 20.7 cm for good quality, 9.9 x 6.5 inches or 25 x 16.6 cm for very good quality, and 8.2 x 5.4 inches or 20.9 x 13.8 cm for excellent quality prints.

The Nikon D2H has a native sensitivity range from ISO 200 to ISO 1600, which can be extended to ISO 200-6400. The corresponding ISO settings for the Ricoh GR are ISO 100 to ISO 25600 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

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 consideration, the GR offers substantially better image quality than the D2H (overall score 38 points higher). The advantage is based on 4.7 bits higher color depth, 3.5 EV in additional dynamic range, and 1.5 stops in additional low light sensitivity. 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 can also record movies. The GR indeed provides for movie recording, while the D2H does not. The highest resolution format that the GR can use is 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the D2H has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the GR relies on live view and the rear LCD for framing. That said, the GR can be equipped with an optional viewfinder – the GV-1. The following table reports on some other key feature differences and similarities of the Nikon D2H, the Ricoh GR, and comparable cameras.

One feature that is present on the D2H, but is missing on the GR is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The Ricoh GR 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 D2H writes its imaging data to Compact Flash cards, while the GR uses SDXC cards.

Connectivity comparison

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 D2H and Ricoh GR and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Nikon D2H (unlike the GR) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the D2H and the GR have been discontinued, but can regularly be found used on ebay. The D2H was replaced by the Nikon D2Hs, while the GR was followed by the Ricoh GR II. Further information on the features and operation of the D2H and GR can be found, respectively, in the Nikon D2H Manual (free pdf) or the online Ricoh GR Manual.

Review summary

So how do things add up? Which of the two cameras – the Nikon D2H or the Ricoh GR – 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.

Arguments in favor of the Nikon D2H:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Easier framing: Has an optical viewfinder for image composition and settings control.
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• Faster burst: Shoots at higher frequency (8 vs 4 flaps/sec) to capture the decisive moment.
• More flexible: Can take a variety of interchangeable lenses, including specialty optics.
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Longer lasting: Can take more shots (2900 versus 290) on a single battery charge.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• More heavily discounted: Has been available for much longer (launched in July 2003).

Reasons to prefer the Ricoh GR:

• More detail: Has more megapixels (16.1 vs 4MP), which boosts linear resolution by 100%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Scores substantially higher (38 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (4.7 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (3.5 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (1.5 stops ISO advantage).
• Broader imaging potential: Can capture not only stills but also 1080/30p video.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1230k vs 211k dots).
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Ready to shoot: Comes with an integrated lens, while the D2H requires a separate lens.
• More compact: Is smaller (117x61mm vs 158x150mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the D2H).
• Easier travel charging: Can be conveniently charged via its USB port.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 9 years and 8 months of technical progress since the D2H launch.

If the count of individual advantages (bullet points above) is taken as a guide, the GR is the clear winner of the contest (17 : 11 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding 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 D2H and the Ricoh GR 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 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 D2H or the GR. 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.

Expert reviews

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.

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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
