Canon 10D vs Epson R-D1

The Canon EOS 10D and the Epson R-D1 are two enthusiast cameras that were officially introduced, respectively, in February 2003 and March 2004. The 10D is a DSLR, while the R-D1 is a rangefinder-style mirrorless camera. Both cameras are equipped with an APS-C sensor. The Canon has a resolution of 6.3 megapixels, whereas the Epson provides 6 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 Canon EOS 10D and the Epson R-D1? 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 Canon 10D and the Epson R-D1 is provided in the side-by-side display below. 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.

Size Canon 10D vs Epson R-D1
Compare 10D versus R-D1 top
Comparison 10D or R-D1 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Epson R-D1 is notably smaller (21 percent) than the Canon 10D. Moreover, the R-D1 is markedly lighter (27 percent) than the 10D. In this context, it is worth noting that neither the 10D nor the R-D1 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. Both cameras have similarly sized sensors, but DSLRs have a larger flange-to-focal plane distance than mirrorless cameras, which imposes contraints on the optical engineering process and generally leads to bigger and heavier lenses. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (10D) and the Leica M Lens Catalog (R-D1).

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, just use the right or left arrows in the table to switch to the respective camera. Alternatively, you can also navigate to the CAM-parator app and make your selection from the full list of cameras there.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

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 10D was launched at a markedly lower price (by 33 percent) than the R-D1, which puts it into a different market segment. 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.

 

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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. 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.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the R-D1 is 8 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (10D) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon 10D and Epson R-D1 sensor measures

Despite having a smaller sensor, the Canon 10D offers a higher resolution of 6.3 megapixels, compared with 6 MP of the Epson 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 7.38μm versus 7.85μm for the R-D1). Moreover, it should be noted that the R-D1 is a somewhat more recent model (by 1 year) than the 10D, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The Canon EOS 10D has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Epson R-D1 are ISO 200 to ISO 1600 (no boost).

10D versus R-D1 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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").

Neither the 10D nor the R-D1 offer Live View, so that they cannot project the live image that the sensor receives onto the rear screen. Moreover, both cameras are still-image focused and cannot record videos.
 

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The 10D and the R-D1 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments.

One difference between the cameras concerns the presence of an on-board flash. The 10D has one, while the R-D1 does not. While the built-in flash of the 10D is not very powerful, it can at times be useful as a fill-in light.

The 10D writes its imaging data to Compact Flash cards, while the R-D1 uses SDHC 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 Canon EOS 10D and Epson R-D1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.

Both the 10D and the R-D1 have been discontinued, but can regularly be found used on eBay. The 10D was replaced by the Canon 20D, while the R-D1 does not have a direct successor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Epson websites.


Review summary

So what is the bottom line? Is there a clear favorite between the Canon 10D and the Epson R-D1? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Advantages of the Canon EOS 10D:

  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • 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.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced into a lower priced category (33 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in February 2003).

ilogo

Reasons to prefer the Epson R-D1:

  • Larger screen: Has a bigger rear LCD (2.0" vs 1.8") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (235k vs 118k dots).
  • More compact: Is smaller (142x89mm vs 150x107mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 230g or 27 percent) and is thus easier to take along.
  • More modern: Was introduced somewhat (1 year) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the 10D comes out slightly ahead of the R-D1 (6 : 5 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.

10D 06:05 R-D1

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 10D or the R-D1. 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 why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
