Epson R-D1 vs Panasonic GF2

The Epson R-D1 and the Panasonic Lumix DMC-GF2 are two digital cameras that were revealed to the public, respectively, in March 2004 and November 2010. The R-D1 is a rangefinder-focusing mirrorless, while the GF2 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (R-D1) and a Four Thirds (GF2) sensor. The Epson has a resolution of 6 megapixels, whereas the Panasonic 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 Panasonic Lumix DMC-GF2? 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

An illustration of the physical size and weight of the Epson R-D1 and the Panasonic GF2 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures are rounded to the nearest millimeter.

The GF2 can be obtained in four different colors (black, silver, red, white), 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 GF2 is considerably smaller (39 percent) than the Epson R-D1. Moreover, the GF2 is substantially lighter (50 percent) than the R-D1. In this context, it is worth noting that neither the R-D1 nor the GF2 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 (GF2).

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

The price is, of course, an important factor in any camera decision. 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 GF2 was launched at a markedly lower price (by 82 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 imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 are more costly to manufacture and tend to 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 Panasonic GF2 a Four Thirds sensor. The sensor area in the GF2 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 GF2 offers a 4:3 aspect.

Despite having a smaller sensor, the GF2 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 4.33μm versus 7.85μm for the R-D1). However, it should be noted that the GF2 is much more recent (by 6 years and 7 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 GF2 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GF2 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 Panasonic Lumix DMC-GF2 are ISO 100 to ISO 6400 (no boost).

In terms of underlying technology, the R-D1 is build around a CCD sensor, while the GF2 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.

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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The GF2 indeed provides for movie recording, while the R-D1 does not. The highest resolution format that the GF2 can use is 1080/60i.

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 GF2 relies on live view and the rear LCD for framing. That said, the GF2 can be equipped with an optional viewfinder – the DMW-LVF1. The table below summarizes some of the other core capabilities of the Epson R-D1 and Panasonic GF2 in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GF2 has a touchscreen, while the R-D1 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The R-D1 writes its imaging data to SDHC cards, while the GF2 uses SDXC 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 Panasonic Lumix DMC-GF2 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 GF2) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the R-D1 and the GF2 have been discontinued, but can regularly be found used on ebay. The GF2 was replaced by the Panasonic GF3, while the R-D1 does not have a direct successor. Further information on the features and operation of the R-D1 and GF2 can be found, respectively, in the Epson R-D1 Manual (free pdf) or the online Panasonic GF2 Manual.

Review summary

So how do things add up? Is the Epson R-D1 better than the Panasonic GF2 or vice versa? The listing below highlights the relative strengths of the two models.

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).

Reasons to prefer the Panasonic Lumix DMC-GF2:

• More detail: Has more megapixels (12 vs 6MP), which boosts linear resolution by 38%.
• Broader imaging potential: Can capture not only stills but also 1080/60i 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).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• Faster burst: Shoots at higher frequency (2.6 vs 1 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (113x68mm vs 142x89mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 310g or 50 percent) and is thus easier to take along.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• More affordable: Was introduced into a lower priced category (82 percent cheaper at launch).
• More modern: Reflects 6 years and 7 months of technical progress since the R-D1 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the GF2 is the clear winner of the contest (12 : 3 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 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 GF2. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why expert reviews are important. 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.

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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
