Canon T2i vs Epson R-D1

The Canon EOS Rebel T2i (called Canon 550D in some regions) and the Epson R-D1 are two digital cameras that were officially introduced, respectively, in February 2010 and March 2004. The T2i is a DSLR, while the R-D1 is a rangefinder-focusing mirrorless camera. Both cameras are equipped with an APS-C sensor. The Canon has a resolution of 17.9 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 Rebel T2i 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 T2i 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 successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

Compare T2i versus R-D1 top
Comparison T2i 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 Canon T2i and the Epson R-D1 are of equal size. However, the R-D1 is markedly heavier (17 percent) than the T2i. In this context, it is worth noting that neither the T2i 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 (T2i) and the Leica M Lens Catalog (R-D1).

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The T2i was launched at a markedly lower price (by 77 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.

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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the R-D1 is 11 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (T2i) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon T2i and Epson R-D1 sensor measures

Despite having a smaller sensor, the Canon T2i offers a higher resolution of 17.9 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 4.31μm versus 7.85μm for the R-D1). However, it should be noted that the T2i is much more recent (by 5 years and 11 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 Canon T2i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T2i for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inches or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inches or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inches or 43.9 x 29.3 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 Canon EOS Rebel T2i has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-12800. The corresponding ISO settings for the Epson R-D1 are ISO 200 to ISO 1600 (no boost).

Many modern cameras are not only capable of taking still images, but can also record movies. The T2i indeed provides movie recording capabilities, while the R-D1 does not. The highest resolution format that the T2i can use is 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The T2i 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. The adjacent table lists some of the other core features of the Canon T2i and Epson R-D1 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The T2i has one, while the R-D1 does not. While the built-in flash of the T2i is not very powerful, it can at times be useful as a fill-in light.

The T2i writes its imaging data to SDXC 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 Rebel T2i and Epson R-D1 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 T2i) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the T2i and the R-D1 have been discontinued, but can regularly be found used on eBay. The T2i was replaced by the Canon T3i, 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 conclusions can be drawn? Is there a clear favorite between the Canon T2i and the Epson R-D1? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Advantages of the Canon EOS Rebel T2i:

  • More detail: Offers more megapixels (17.9 vs 6MP) with a 72% higher linear resolution.
  • Broader imaging potential: Can record not only still images but also 1080/30p movies.
  • 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 shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
  • Faster burst: Shoots at higher frequency (3.7 vs 1 flaps/sec) to capture the decisive moment.
  • Less heavy: Is lighter (by 90g or 15 percent) and hence easier to carry around.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced into a lower priced category (77 percent cheaper at launch).
  • More modern: Reflects 5 years and 11 months of technical progress since the R-D1 launch.

ilogo

Arguments in favor of the Epson R-D1:

  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • More heavily discounted: Has been around for much longer (launched in March 2004).

If the number of relative strengths (bullet points above) is taken as a guide, the T2i is the clear winner of the match-up (10 : 2 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 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.

T2i 10:02 R-D1

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the T2i or the R-D1 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 adjacent summary-table relays the overall verdicts of several of the most popular camera 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.

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

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
