Canon XSi vs Epson R-D1
The Canon EOS Rebel XSi (called Canon 450D in some regions) and the Epson R-D1 are two digital cameras that were announced, respectively, in January 2008 and March 2004. The XSi 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 12.2 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 XSi 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.
An illustration of the physical size and weight of the Canon XSi 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 views from the front, the top, and the rear side are shown. All width, height and depth measures are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon XSi and the Epson R-D1 are of equal size. However, the R-D1 is markedly heavier (18 percent) than the XSi. In this context, it is worth noting that neither the XSi 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 (XSi) and the Leica M Lens Catalog (R-D1).
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.

Any camera decision will obviously take relative prices into account. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The XSi was launched at a markedly lower price (by 73 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 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 12 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (XSi) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Despite having a smaller sensor, the Canon XSi offers a higher resolution of 12.2 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 5.19μm versus 7.85μm for the R-D1). However, it should be noted that the XSi is much more recent (by 3 years and 10 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 XSi implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the XSi for good quality output (200 dots per inch) amounts to 21.4 x 14.2 inches or 54.3 x 36.2 cm, for very good quality (250 dpi) 17.1 x 11.4 inches or 43.4 x 28.9 cm, and for excellent quality (300 dpi) 14.2 x 9.5 inches or 36.2 x 24.1 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 XSi has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Epson R-D1 are ISO 200 to ISO 1600 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Apart from body and sensor, cameras can and do differ across a range of features. The XSi 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 table below summarizes some of the other core capabilities of the Canon XSi and Epson R-D1 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 XSi has one, while the R-D1 does not. While the built-in flash of the XSi is not very powerful, it can at times be useful as a fill-in light.
Concerning the storage of imaging data, both the XSi and the R-D1 write their files to SDHC 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 Canon EOS Rebel XSi 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 XSi) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the XSi and the R-D1 have been discontinued, but can regularly be found used on eBay. The XSi was replaced by the Canon T1i, 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.
So how do things add up? Is there a clear favorite between the Canon XSi and the Epson R-D1? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Canon EOS Rebel XSi:
- More detail: Offers more megapixels (12.2 vs 6MP) with a 42% higher linear resolution.
- Larger screen: Has a bigger rear LCD (3.0" vs 2.0") for image review and settings control.
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
- Faster burst: Shoots at higher frequency (3.5 vs 1 flaps/sec) to capture the decisive moment.
- Less heavy: Is lighter (by 96g 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 (73 percent cheaper at launch).
- More modern: Reflects 3 years and 10 months of technical progress since the R-D1 launch.
Advantages 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 count of individual advantages (bullet points above) is taken as a guide, the XSi is the clear winner of the match-up (8 : 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 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.
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 XSi or the R-D1. 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 why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera 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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
