Epson R-D1 vs Panasonic LX100
The Epson R-D1 and the Panasonic Lumix DMC-LX100 are two enthusiast cameras that were announced, respectively, in March 2004 and September 2014. The R-D1 is a rangefinder-style mirrorless camera, while the LX100 is a fixed lens compact. The cameras are based on an APS-C (R-D1) and a Four Thirds (LX100) sensor. The Epson has a resolution of 6 megapixels, whereas the Panasonic provides 12.7 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 Panasonic Lumix DMC-LX100? 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.
The side-by-side display below illustrates the physical size and weight of the Epson R-D1 and the Panasonic LX100. 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.
The LX100 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 Panasonic LX100 is considerably smaller (40 percent) than the Epson R-D1. In this context, it is worth noting that neither the R-D1 nor the LX100 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the LX100 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 adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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.

Any camera decision will obviously take relative prices into account. 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 LX100 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Epson R-D1 features an APS-C sensor and the Panasonic LX100 a Four Thirds sensor. The sensor area in the LX100 is 50 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.2. The sensor in the R-D1 has a native 3:2 aspect ratio, while the one in the LX100 offers a 4:3 aspect. The LX100 has the particularity of featuring a switch that allows to toggle between multiple aspect ratios, while maintaining the same field of view and full image resolution.
Despite having a smaller sensor, the LX100 offers a higher resolution of 12.7 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 3.82μm versus 7.85μm for the R-D1). However, it should be noted that the LX100 is much more recent (by 10 years and 6 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 Panasonic LX100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the LX100 for good quality output (200 dots per inch) amounts to 20.6 x 15.4 inches or 52.2 x 39.2 cm, for very good quality (250 dpi) 16.4 x 12.4 inches or 41.8 x 31.4 cm, and for excellent quality (300 dpi) 13.7 x 10.3 inches or 34.8 x 26.1 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 Panasonic Lumix DMC-LX100 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
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.

Many modern cameras cannot only take still pictures, but also record videos. The LX100 indeed provides for movie recording, while the R-D1 does not. The highest resolution format that the LX100 can use is 4K/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the LX100 has an electronic viewfinder (2764k dots), while the R-D1 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The adjacent table lists some of the other core features of the Epson R-D1 and Panasonic LX100 along with similar information for a selection of comparators.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the LX100 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The Panasonic LX100 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
The R-D1 writes its imaging data to SDHC cards, while the LX100 uses SDXC cards. The LX100 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the R-D1 cannot take advantage of Ultra High Speed SD cards.
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 Panasonic Lumix DMC-LX100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the LX100 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the R-D1 does not provide wifi capability.
Studio photographers will appreciate that the Epson R-D1 (unlike the LX100) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The LX100 is a recent model that features in the current product line-up of Panasonic. In contrast, the R-D1 has been discontinued (but can be found pre-owned on eBay). There has not been a direct replacement model for the R-D1 from Epson. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Epson and Panasonic websites.
So how do things add up? Which of the two cameras – the Epson R-D1 or the Panasonic LX100 – 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.
Arguments in favor of the Epson R-D1:
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- 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 Panasonic Lumix DMC-LX100:
- More detail: Has more megapixels (12.7 vs 6MP), which boosts linear resolution by 42%.
- Flexible image proportions: Has a multi-aspect sensor that allows for alternative image shapes.
- Broader imaging potential: Can capture not only stills but also 4K/30p video.
- More framing info: Has an electronic viewfinder that displays shooting data.
- 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 (921k vs 235k dots).
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
- Faster burst: Shoots at higher frequency (11 vs 1 flaps/sec) to capture the decisive moment.
- Less disturbing: Has an electronic shutter option for completely silent shooting.

If the count of individual advantages (bullet points above) is taken as a guide, the LX100 is the clear winner of the contest (19 : 4 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the R-D1 or the LX100. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

The review scores listed above should be treated 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
