Going beyond this snapshot of core features and characteristics, what are the differences between the Epson R-D1 and the Nikon D40? 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 D40. 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 dimensions are rounded to the nearest millimeter.

Size Epson R-D1 vs Nikon D40
Compare R-D1 versus D40 top
Comparison R-D1 or D40 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D40 is notably smaller (8 percent) than the Epson R-D1. Moreover, the D40 is markedly lighter (16 percent) than the R-D1. In this context, it is worth noting that neither the R-D1 nor the D40 are weather-sealed.

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 (D40).

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The D40 was launched at a markedly lower price (by 83 percent) than the R-D1, 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 size of the imaging sensor is a crucial determinant 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. 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 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.

Epson R-D1 and Nikon D40 sensor measures

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 6 megapixels. This similarity in sensor specs implies that both the R-D1 and the D40 have the same pixel density, as well as the same pixel size. It should, however, be noted that the D40 is much more recent (by 2 years and 8 months) than the R-D1, and its sensor will have benefitted from technological advances during this time.

The Epson R-D1 has a native sensitivity range from ISO 200 to ISO 1600. The corresponding ISO settings for the Nikon D40 are ISO 200 to ISO 1600, 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.

R-D1 versus D40 MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Note: DXO values in italics represent estimates based on sensor size and age.
Neither the R-D1 nor the D40 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 variety of features. The R-D1 and the D40 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 D40 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The D40 has one, while the R-D1 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.

Concerning the storage of imaging data, both the R-D1 and the D40 write their files to SDHC 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 D40 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Epson R-D1 (unlike the D40) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the R-D1 and the D40 have been discontinued, but can regularly be found used on ebay. The D40 was replaced by the Nikon D40X, 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 how do things add up? Is there a clear favorite between the Epson R-D1 and the Nikon D40? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Advantages of the Epson R-D1:

  • 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 March 2004).

ilogo

Arguments in favor of the Nikon D40:

  • 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 (1/4000s vs 1/2000s) to freeze action.
  • Faster burst: Shoots at higher frequency (2.5 vs 1 flaps/sec) to capture the decisive moment.
  • Less heavy: Has a lower weight (by 98g or 16 percent) and is thus easier to take along.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (83 percent cheaper at launch).
  • More modern: Reflects 2 years and 8 months of technical progress since the R-D1 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the D40 is the clear winner of the contest (7 : 2 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 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.

R-D1 02:07 D40

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 D40 in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major 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.

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

The above review scores should be interpreted with care, 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
