Epson R-D1 vs Olympus E-PL2

The Epson R-D1 and the Olympus PEN E-PL2 are two digital cameras that were revealed to the public, respectively, in March 2004 and January 2011. The R-D1 is a rangefinder-focusing mirrorless, while the E-PL2 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (R-D1) and a Four Thirds (E-PL2) sensor. The Epson has a resolution of 6 megapixels, whereas the Olympus provides 12.2 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Epson R-D1 and the Olympus E-PL2. 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.

The E-PL2 can be obtained in four different colors (black, silver, red, white), while the R-D1 is only available in black.

Size Epson R-D1 vs Olympus E-PL2
Compare R-D1 versus E-PL2 top
Comparison R-D1 or E-PL2 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-PL2 is considerably smaller (35 percent) than the Epson R-D1. Moreover, the E-PL2 is substantially lighter (42 percent) than the R-D1. In this context, it is worth noting that neither the R-D1 nor the E-PL2 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Leica M Lens Catalog (R-D1) and the Micro Four Thirds Lens Catalog (E-PL2).

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.

Any camera decision will obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The E-PL2 was launched at a markedly lower price (by 80 percent) than the R-D1, which puts it into a different market segment. 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 sensor inside a digital camera is one of the key determinants 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 Olympus E-PL2 a Four Thirds sensor. The sensor area in the E-PL2 is 39 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the R-D1 has a native 3:2 aspect ratio, while the one in the E-PL2 offers a 4:3 aspect.

Epson R-D1 and Olympus E-PL2 sensor measures

Despite having a smaller sensor, the E-PL2 offers a higher resolution of 12.2 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 4.29μm versus 7.85μm for the R-D1). However, it should be noted that the E-PL2 is much more recent (by 6 years and 9 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 E-PL2 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-PL2 for good quality output (200 dots per inch) amounts to 20.2 x 15.1 inches or 51.2 x 38.4 cm, for very good quality (250 dpi) 16.1 x 12.1 inches or 41 x 30.7 cm, and for excellent quality (300 dpi) 13.4 x 10.1 inches or 34.1 x 25.6 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 PEN E-PL2 are ISO 200 to ISO 6400 (no boost).

In terms of underlying technology, the R-D1 is build around a CCD sensor, while the E-PL2 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.

R-D1 versus E-PL2 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.

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 E-PL2 relies on live view and the rear LCD for framing. That said, the E-PL2 can be equipped with an optional viewfinder – the VF-2. The table below summarizes some of the other core capabilities of the Epson R-D1 and Olympus E-PL2 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 E-PL2 has one, while the R-D1 does not. While the built-in flash of the E-PL2 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 E-PL2 write their files to SDHC cards.

Studio photographers will appreciate that the Epson R-D1 (unlike the E-PL2) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the R-D1 and the E-PL2 have been discontinued, but can regularly be found used on ebay. The E-PL2 was replaced by the Olympus E-PL3, while the R-D1 does not have a direct successor. Further information on the features and operation of the R-D1 and E-PL2 can be found, respectively, in the Epson R-D1 Manual (free pdf) or the online Olympus E-PL2 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Epson R-D1 or the Olympus E-PL2 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Advantages of the Epson R-D1:

  • Easier framing: Has an optical viewfinder for image composition and settings control.
  • 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

Reasons to prefer the Olympus PEN E-PL2:

  • More detail: Has more megapixels (12.2 vs 6MP), which boosts linear resolution by 40%.
  • Broader imaging potential: Can capture not only stills but also 720/30p 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 (460k vs 235k dots).
  • Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
  • Faster burst: Shoots at higher frequency (3 vs 1 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (114x72mm vs 142x89mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 258g or 42 percent) and is thus easier to take along.
  • 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 into a lower priced category (80 percent cheaper at launch).
  • More modern: Reflects 6 years and 9 months of technical progress since the R-D1 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the E-PL2 is the clear winner of the contest (12 : 3 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 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.

R-D1 03:12 E-PL2

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the R-D1 or the E-PL2 perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

Expert reviews

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], 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.

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

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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.
