Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX610 HS 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

The side-by-side display below illustrates the physical size and weight of the Canon SX610 and the Epson R-D1. 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.

The SX610 can be obtained in three different colors (black, 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 Epson R-D1 is considerably larger (97 percent) than the Canon SX610. In this context, it is worth noting that neither the SX610 nor the R-D1 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX610 has a lens built in, whereas the R-D1 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the R-D1 and their specifications in the Leica M Lens Catalog.

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 SX610 was launched at a lower price than the R-D1, despite having a lens built in. 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 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.

Of the two cameras under consideration, the Canon SX610 features a 1/2.3-inch sensor and the Epson R-D1 an APS-C sensor. The sensor area in the R-D1 is 1221 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.5. The sensor in the SX610 has a native 4:3 aspect ratio, while the one in the R-D1 offers a 3:2 aspect.

Despite having a smaller sensor, the Canon SX610 offers a higher resolution of 20.2 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 1.18μm versus 7.85μm for the R-D1). However, it should be noted that the SX610 is much more recent (by 10 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. Coming back to sensor resolution, it should be mentioned that the SX610 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Canon SX610 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SX610 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 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 PowerShot SX610 HS has a native sensitivity range from ISO 80 to ISO 3200. The corresponding ISO settings for the Epson R-D1 are ISO 200 to ISO 1600 (no boost).

In terms of underlying technology, the SX610 is build around a BSI-CMOS sensor, while the R-D1 uses a CCD 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 assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. The SX610 indeed provides movie recording capabilities, while the R-D1 does not. The highest resolution format that the SX610 can use is 1080/30p.

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 SX610 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon SX610 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 SX610 has one, while the R-D1 does not. While the built-in flash of the SX610 is not very powerful, it can at times be useful as a fill-in light.

The SX610 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 PowerShot SX610 HS and Epson R-D1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SX610 offers wifi support, while the R-D1 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Studio photographers will appreciate that the Epson R-D1 (unlike the SX610) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the SX610 and the R-D1 have been discontinued, but can regularly be found used on ebay. The SX610 was replaced by the Canon SX620, while the R-D1 does not have a direct successor. Further information on the features and operation of the SX610 and R-D1 can be found, respectively, in the Canon SX610 Manual (free pdf) or the online Epson R-D1 Manual.

Review summary

So what conclusions can be drawn? Is the Canon SX610 better than the Epson R-D1 or vice versa? The listing below highlights the relative strengths of the two models.

Advantages of the Canon PowerShot SX610 HS:

• More detail: Offers more megapixels (20.2 vs 6MP) with a 79% higher linear resolution.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• 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 (922k vs 235k dots).
• Faster burst: Shoots at higher frequency (2.5 vs 1 flaps/sec) to capture the decisive moment.
• Ready to shoot: Has a lens built-in, whereas the R-D1 requires a separate lens.
• More compact: Is smaller (105x61mm vs 142x89mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the R-D1).
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 10 years and 9 months of technical progress since the R-D1 launch.

Reasons to prefer the Epson R-D1:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
• Richer colors: The pixel size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
• Easier framing: Has an optical viewfinder for image composition and settings control.
• More flexible: Takes interchangeable lenses and can thus be used with different optics.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• 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 SX610 is the clear winner of the match-up (15 : 10 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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 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 SX610 or the R-D1 perform in practice. 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 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], 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 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 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.
