Epson R-D1 vs Nikon D1H

The Epson R-D1 and the Nikon D1H are two digital cameras that were officially introduced, respectively, in March 2004 and February 2001. The R-D1 is a rangefinder-focusing mirrorless camera, while the D1H is a DSLR. Both cameras are equipped with an APS-C sensor. The Epson has a resolution of 6 megapixels, whereas the Nikon provides 2.6 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 Epson R-D1 and the Nikon D1H? 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

The physical size and weight of the Epson R-D1 and the Nikon D1H 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 dimensions 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 Nikon D1H is considerably larger (90 percent) than the Epson R-D1. Moreover, the D1H is substantially heavier (77 percent) than the R-D1. It is noteworthy in this context that the D1H is splash and dust-proof, while the R-D1 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. Both cameras have similarly sized sensors, but DSLRs have a larger flange-to-focal plane distance than mirrorless cameras, which imposes contraints on the optical engineering process and generally leads to bigger and heavier lenses. You can compare the optics available for the two cameras in the Leica M Lens Catalog (R-D1) and the Nikon Lens Catalog (D1H).

As can be seen in the images above, the D1H has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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 obviously take relative prices into account. 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 R-D1 was launched at a markedly lower price (by 33 percent) than the D1H, which puts it into a different 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.

Sensor comparison

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. 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 associated with larger, more expensive camera bodies and lenses.

Both cameras under consideration feature an APS-C sensor and have a format factor (sometimes also referred to as "crop factor") of 1.5. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

While the two cameras under review share the same sensor size, the R-D1 offers a higher resolution of 6 megapixels, compared with 2.6 MP of the D1H. This megapixels advantage translates into a 50 percent gain in linear resolution. On the other hand, these sensor specs imply that the R-D1 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 7.85μm versus 11.93μm for the D1H). In this context, it should be noted, however, that the R-D1 is much more recent (by 3 years and 1 month) than the D1H, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.

The resolution advantage of the Epson R-D1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the R-D1 for good quality output (200 dots per inch) amounts to 15 x 10 inches or 38.2 x 25.4 cm, for very good quality (250 dpi) 12 x 8 inches or 30.6 x 20.3 cm, and for excellent quality (300 dpi) 10 x 6.7 inches or 25.5 x 16.9 cm. The corresponding values for the Nikon D1H are 10 x 6.6 inches or 25.4 x 16.7 cm for good quality, 8 x 5.2 inches or 20.3 x 13.3 cm for very good quality, and 6.7 x 4.4 inches or 16.9 x 11.1 cm for excellent quality prints.

The Epson R-D1 has a native sensitivity range from ISO 200 to ISO 1600. The corresponding ISO settings for the Nikon D1H are ISO 200 to ISO 800, with the possibility to increase the ISO range to 200-3200.

Technology-wise, both cameras are equipped with CCD (Charged Coupled Device) 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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The R-D1 and the D1H are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The adjacent table lists some of the other core features of the Epson R-D1 and Nikon D1H along with similar information for a selection of comparators.

One feature that is present on the D1H, but is missing on the R-D1 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 R-D1 writes its imaging data to SDHC cards, while the D1H uses Compact Flash 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 Epson R-D1 and Nikon D1H and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.

Both the R-D1 and the D1H have been discontinued, but can regularly be found used on ebay. The D1H was replaced by the Nikon D2H, while the R-D1 does not have a direct successor. Further information on the features and operation of the R-D1 and D1H can be found, respectively, in the Epson R-D1 Manual (free pdf) or the online Nikon D1H Manual.

Review summary

So how do things add up? Which of the two cameras – the Epson R-D1 or the Nikon D1H – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Epson R-D1:

• More detail: Offers more megapixels (6 vs 2.6MP) with a 51% higher linear resolution.
• More detailed LCD: Has a higher resolution rear screen (235k vs 120k dots).
• More compact: Is smaller (142x89mm vs 157x153mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 480g or 44 percent) and hence easier to carry around.
• More affordable: Was introduced into a lower priced category (33 percent cheaper at launch).
• More modern: Reflects 3 years and 1 month of technical progress since the D1H launch.

Advantages of the Nikon D1H:

• Easier setting verification: Features a control panel on top to check shooting parameters.
• Faster shutter: Has higher mechanical shutter speed (1/16000s vs 1/2000s) to freeze action.
• Faster burst: Shoots at higher frequency (5 vs 1 flaps/sec) to capture the decisive moment.
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• More heavily discounted: Has been around for much longer (launched in February 2001).

If the number of relative strengths (bullet points above) is taken as a guide, the match-up finishes in a tie (6 points each). 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.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the R-D1 or the D1H. 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.

Expert reviews

This is why expert reviews are important. 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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
