Epson R-D1 vs Nikon D2H

The Epson R-D1 and the Nikon D2H are two digital cameras that were revealed to the public, respectively, in March 2004 and July 2003. The R-D1 is a rangefinder-style mirrorless camera, while the D2H is a DSLR. Both cameras are equipped with an APS-C sensor. The Epson has a resolution of 6 megapixels, whereas the Nikon provides 4 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 D2H? 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 side-by-side display below illustrates the physical size and weight of the Epson R-D1 and the Nikon D2H. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

Size Epson R-D1 vs Nikon D2H
Compare R-D1 versus D2H top
Comparison R-D1 or D2H rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D2H is considerably larger (88 percent) than the Epson R-D1. Moreover, the D2H is substantially heavier (73 percent) than the R-D1. It is noteworthy in this context that the D2H 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 (D2H).

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 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.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

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 R-D1 was launched at a somewhat lower price (by 14 percent) than the D2H, which makes it more attractive for photographers on a tight budget. 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 imaging sensor is a crucial determinant 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 D2H is 2 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.

Epson R-D1 and Nikon D2H sensor measures

With 6MP, the R-D1 offers a higher resolution than the D2H (4MP), but the R-D1 has smaller individual pixels (pixel pitch of 7.85μm versus 9.50μm for the D2H). However, the R-D1 is a somewhat more recent model (by 7 months) than the D2H, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.

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 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 Epson R-D1 has a native sensitivity range from ISO 200 to ISO 1600. The corresponding ISO settings for the Nikon D2H are ISO 200 to ISO 1600, with the possibility to increase the ISO range to 200-6400.

R-D1 versus D2H MP

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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Neither the R-D1 nor the D2H offer Live View, so that they cannot project the live image that the sensor receives onto the rear screen. Moreover, both cameras are still-image focused and cannot record videos.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The R-D1 and the D2H 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 table below summarizes some of the other core capabilities of the Epson R-D1 and Nikon D2H in connection with corresponding information for a sample of similar cameras.

One feature that is present on the D2H, 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 D2H uses Compact Flash cards.

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 D2H have been discontinued, but can regularly be found used on eBay. The D2H was replaced by the Nikon D2Hs, while the R-D1 does not have a direct successor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Epson and Nikon websites.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Epson R-D1 or the Nikon D2H – 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.

ilogo

Advantages of the Epson R-D1:

  • More detail: Offers more megapixels (6 vs 4MP) with a 22% higher linear resolution.
  • More detailed LCD: Has a higher resolution rear screen (235k vs 211k dots).
  • More compact: Is smaller (142x89mm vs 158x150mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 450g or 42 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced segment (14 percent cheaper at launch).
  • More modern: Is somewhat more recent (announced 7 months after the D2H).

ilogo

Reasons to prefer the Nikon D2H:

  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • Larger screen: Has a bigger rear LCD (2.5" vs 2.0") for image review and settings control.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/2000s) to freeze action.
  • Faster burst: Shoots at higher frequency (8 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 on the market for longer (launched in July 2003).

If the number of relative strengths (bullet points above) is taken as a guide, the D2H comes out slightly ahead of the R-D1 (7 : 6 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. 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.

R-D1 06:07 D2H

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 R-D1 and the D2H in practical situations. 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 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], 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

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. 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.
