Epson R-D1 vs Sony RX100
The Epson R-D1 and the Sony Cyber-shot DSC-RX100 are two digital cameras that were officially introduced, respectively, in March 2004 and June 2012. The R-D1 is a rangefinder-focusing mirrorless camera, while the RX100 is a fixed lens compact. The cameras are based on an APS-C (R-D1) and an one-inch (RX100) sensor. The Epson has a resolution of 6 megapixels, whereas the Sony provides 20 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 Sony Cyber-shot DSC-RX100? 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 Sony RX100. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size 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 Sony RX100 is considerably smaller (53 percent) than the Epson R-D1. In this context, it is worth noting that neither the R-D1 nor the RX100 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX100 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 power pack in the RX100 can be charged via the USB port, which can be very convenient when travelling.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The RX100 was launched at a lower price than the R-D1, despite having a lens built in. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
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. 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.
Of the two cameras under consideration, the Epson R-D1 features an APS-C sensor and the Sony RX100 an one-inch sensor. The sensor area in the RX100 is 69 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Despite having a smaller sensor, the RX100 offers a higher resolution of 20 megapixels, compared with 6 MP of the R-D1. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 2.41μm versus 7.85μm for the R-D1). However, it should be noted that the RX100 is much more recent (by 8 years and 2 months) than the R-D1, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The resolution advantage of the Sony RX100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX100 for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 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 Sony Cyber-shot DSC-RX100 are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-25600.
In terms of underlying technology, the R-D1 is build around a CCD sensor, while the RX100 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.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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").

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The RX100 indeed provides for movie recording, while the R-D1 does not. The highest resolution format that the RX100 can use is 1080/60p.
Feature comparison
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the R-D1 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the RX100 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 Sony RX100 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 RX100 has one, while the R-D1 does not. While the built-in flash of the RX100 is not very powerful, it can at times be useful as a fill-in light.
The R-D1 writes its imaging data to SDHC cards, while the RX100 uses SDXC or Memory Stick PRO Duo 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 Sony Cyber-shot DSC-RX100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the R-D1 has a hotshoe, while the RX100 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Studio photographers will appreciate that the Epson R-D1 (unlike the RX100) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the R-D1 and the RX100 have been discontinued, but can regularly be found used on ebay. The RX100 was replaced by the Sony RX100 II, while the R-D1 does not have a direct successor. Further information on the features and operation of the R-D1 and RX100 can be found, respectively, in the Epson R-D1 Manual (free pdf) or the online Sony RX100 Manual.
Review summary
So how do things add up? Is the Epson R-D1 better than the Sony RX100 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Advantages of 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 lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- 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).
Reasons to prefer the Sony Cyber-shot DSC-RX100:
- More detail: Has more megapixels (20 vs 6MP), which boosts linear resolution by 82%.
- Broader imaging potential: Can capture not only stills but also 1080/60p video.
- Larger screen: Has a bigger rear LCD (3.0" vs 2.0") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (1229k vs 235k dots).
- Faster burst: Shoots at higher frequency (10 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 (102x58mm 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 travel charging: Can be conveniently charged via its USB port.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- 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 8 years and 2 months of technical progress since the R-D1 launch.
If the count of relative strengths (bullet points above) is taken as a measure, the RX100 is the clear winner of the contest (13 : 5 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 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.
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 RX100. 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 hands-on reviews by experts 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
