Epson R-D1 vs Olympus TG-6
The Epson R-D1 and the Olympus Tough TG-6 are two digital cameras that were officially introduced, respectively, in March 2004 and May 2019. The R-D1 is a rangefinder-style mirrorless camera, while the TG-6 is a fixed lens compact. The cameras are based on an APS-C (R-D1) and a 1/2.3-inch (TG-6) sensor. The Epson has a resolution of 6 megapixels, whereas the Olympus provides 12 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 Olympus Tough TG-6? 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 Olympus TG-6. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.
The TG-6 can be obtained in two different colors (black, red), 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 Olympus TG-6 is considerably smaller (41 percent) than the Epson R-D1. It is noteworthy in this context that the TG-6 is splash and dust-proof, while the R-D1 does not feature any corresponding weather-sealing. More than that, the TG-6 is water-proof up to 15m and can, thus, be used for underwater photography.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the TG-6 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 TG-6 can be charged via the USB port, which can be very convenient when travelling.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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.

|Notes: 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 TG-6 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
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 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 Olympus TG-6 a 1/2.3-inch sensor. The sensor area in the TG-6 is 92 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 5.6. The sensor in the R-D1 has a native 3:2 aspect ratio, while the one in the TG-6 offers a 4:3 aspect.
Despite having a smaller sensor, the TG-6 offers a higher resolution of 12 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 1.53μm versus 7.85μm for the R-D1). However, it should be noted that the TG-6 is much more recent (by 15 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 Olympus TG-6 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the TG-6 for good quality output (200 dots per inch) amounts to 20 x 15 inches or 50.8 x 38.1 cm, for very good quality (250 dpi) 16 x 12 inches or 40.6 x 30.5 cm, and for excellent quality (300 dpi) 13.3 x 10 inches or 33.9 x 25.4 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 Olympus Tough TG-6 are ISO 100 to ISO 12800 (no boost).
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.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The TG-6 indeed provides for movie recording, while the R-D1 does not. The highest resolution format that the TG-6 can use is 4K/30p.
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 TG-6 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Epson R-D1, the Olympus TG-6, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The TG-6 has one, while the R-D1 does not. While the built-in flash of the TG-6 is not very powerful, it can at times be useful as a fill-in light.
The Olympus TG-6 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 TG-6 uses SDXC cards. The TG-6 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 Olympus Tough TG-6 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 TG-6 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 TG-6) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Travel and landscape photographers will find it useful that the TG-6 has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.
The TG-6 is a recent model that features in the current product line-up of Olympus. 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 Olympus websites.
So how do things add up? Which of the two cameras – the Epson R-D1 or the Olympus TG-6 – 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.
Reasons to prefer the Epson R-D1:
- Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
- Richer colors: The pixel size advantage translates into images with better, more accurate colors.
- More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
- Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
- 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).
Arguments in favor of the Olympus Tough TG-6:
- More detail: Has more megapixels (12 vs 6MP), which boosts linear resolution by 38%.
- Broader imaging potential: Can capture not only stills but also 4K/30p 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 (1040k vs 235k dots).
- Faster burst: Shoots at higher frequency (20 vs 1 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Ready to shoot: Has an integrated lens, whereas the R-D1 necessitates an extra lens.
- More compact: Is smaller (113x66mm 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.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- Water-proof: Is rugged and sealed and can thus be used for underwater photography (up to 15m).
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- Easier geotagging: Features an internal GPS sensor to log localization data.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More modern: Reflects 15 years and 2 months of technical progress since the R-D1 launch.
If the number of relative strengths (bullet points above) is taken as a guide, the TG-6 is the clear winner of the contest (19 : 9 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 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the R-D1 or the TG-6 perform in practice. 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 above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
