Going beyond this snapshot of core features and characteristics, what are the differences between the Epson R-D1 and the Leica X1? 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 Leica X1. 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.

The X1 can be obtained in two different colors (black, silver), while the R-D1 is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Leica X1 is considerably smaller (41 percent) than the Epson R-D1. In this context, it is worth noting that neither the R-D1 nor the X1 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the X1 has a lens built in, whereas the R-D1 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 R-D1 and their specifications in the Leica M Lens Catalog.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

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 X1 was launched at a lower price than the R-D1, 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the 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.

While the two cameras under review share the same sensor size, the X1 offers a higher resolution of 12.2 megapixels, compared with 6 MP of the R-D1. This megapixels advantage translates into a 42 percent gain in linear resolution. On the other hand, these sensor specs imply that the X1 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 5.51μm versus 7.85μm for the R-D1). However, it should be noted that the X1 is much more recent (by 5 years and 6 months) than the R-D1, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.

The resolution advantage of the Leica X1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X1 for good quality output (200 dots per inch) amounts to 21.4 x 14.3 inches or 54.3 x 36.3 cm, for very good quality (250 dpi) 17.1 x 11.4 inches or 43.4 x 29 cm, and for excellent quality (300 dpi) 14.2 x 9.5 inches or 36.2 x 24.2 cm. The corresponding values for the Epson R-D1 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 Epson R-D1 has a native sensitivity range from ISO 200 to ISO 1600. The corresponding ISO settings for the Leica X1 are ISO 100 to ISO 3200 (no boost).

In terms of underlying technology, the R-D1 is build around a CCD sensor, while the X1 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 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the R-D1 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the X1 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Epson R-D1 and Leica X1 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 X1 has one, while the R-D1 does not. While the built-in flash of the X1 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 X1 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 Leica X1 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 X1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the R-D1 and the X1 have been discontinued, but can regularly be found used on ebay. The X1 was replaced by the Leica X2, while the R-D1 does not have a direct successor. Further information on the features and operation of the R-D1 and X1 can be found, respectively, in the Epson R-D1 Manual (free pdf) or the online Leica X1 Manual.

Review summary

So how do things add up? Is the Epson R-D1 better than the Leica X1 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Epson R-D1:

• Easier framing: Has an optical viewfinder for image composition and settings control.
• More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
• 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).

Advantages of the Leica X1:

• More detail: Has more megapixels (12.2 vs 6MP), which boosts linear resolution by 42%.
• Larger screen: Has a bigger rear LCD (2.7" vs 2.0") for image review and settings control.
• Faster burst: Shoots at higher frequency (3 vs 1 flaps/sec) to capture the decisive moment.
• Ready to shoot: Has an integrated lens, whereas the R-D1 necessitates an extra lens.
• More compact: Is smaller (124x60mm vs 142x89mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the R-D1).
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 5 years and 6 months of technical progress since the R-D1 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the X1 is the clear winner of the contest (10 : 4 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the R-D1 or the X1 perform in practice. 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], 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 above review scores should be interpreted 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
