Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS-1Ds and the Canon EOS 5DS R? 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 physical size and weight of the Canon 1Ds and the Canon 5DS R are illustrated 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 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 5DS R is notably smaller (28 percent) than the Canon 1Ds. Moreover, the 5DS R is markedly lighter (26 percent) than the 1Ds. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Canon EF Lens Catalog.

Concerning battery life, the 1Ds gets 600 shots out of its Canon NP-E3 battery, while the 5DS R can take 700 images on a single charge of its Canon LP-E6 power pack. As can be seen in the images above, the 1Ds has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. In order to provide similar functionality for the 5DS R, Canon provides the BG-E11 vertical grip as an optional accessory (see here on ebay).

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

Any camera decision will naturally be influenced heavily by the price. 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 5DS R was launched at a markedly lower price (by 59 percent) than the 1Ds, 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. 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Both cameras under consideration feature a full frame sensor, but their sensors differ slightly in size. The sensor area in the 5DS R is 1 percent bigger. They nevertheless have the same format factor of 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 50.3MP, the 5DS R offers a higher resolution than the 1Ds (11MP), but the 5DS R has smaller individual pixels (pixel pitch of 4.14μm versus 8.83μm for the 1Ds). Yet, the 5DS R is a much more recent model (by 12 years and 4 months) than the 1Ds, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the 5DS R has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Canon 5DS R implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 5DS R for good quality output (200 dots per inch) amounts to 43.4 x 29 inches or 110.3 x 73.6 cm, for very good quality (250 dpi) 34.8 x 23.2 inches or 88.3 x 58.8 cm, and for excellent quality (300 dpi) 29 x 19.3 inches or 73.6 x 49 cm. The corresponding values for the Canon 1Ds are 20.3 x 13.5 inches or 51.6 x 34.3 cm for good quality, 16.3 x 10.8 inches or 41.3 x 27.5 cm for very good quality, and 13.5 x 9 inches or 34.4 x 22.9 cm for excellent quality prints.

The Canon EOS-1Ds has a native sensitivity range from ISO 100 to ISO 1250, which can be extended to ISO 50-1250. The corresponding ISO settings for the Canon EOS 5DS R are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 50-12800.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

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"). Of the two cameras under consideration, the 5DS R offers substantially better image quality than the 1Ds (overall score 23 points higher). The advantage is based on 2.8 bits higher color depth, 1.4 EV in additional dynamic range, and 1.3 stops in additional low light sensitivity. 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 are not only capable of taking still images, but can also record movies. The 5DS R indeed provides for movie recording, while the 1Ds does not. The highest resolution format that the 5DS R can use is 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The 1Ds and the 5DS R 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 viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the 5DS R has a higher magnification than the one of the 1Ds (0.71x vs 0.70x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Canon 1Ds, the Canon 5DS R, and comparable cameras.

The Canon 5DS R has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

The 1Ds writes its imaging data to Compact Flash cards, while the 5DS R uses Compact Flash or SDXC cards. The 5DS R features dual card slots, which can be very useful in case a memory card fails. In contrast, the 1Ds only has one slot.

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-1Ds and Canon EOS 5DS R 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 1Ds and the 5DS R have been discontinued, but can regularly be found used on ebay. The 1Ds was replaced by the Canon 1Ds Mark II, while the 5DS R does not have a direct successor. Further information on the features and operation of the 1Ds and 5DS R can be found, respectively, in the Canon 1Ds Manual (free pdf) or the online Canon 5DS R Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Canon 1Ds and the Canon 5DS R? Which camera is better? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Canon EOS-1Ds:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• More heavily discounted: Has been available for much longer (launched in September 2002).

Arguments in favor of the Canon EOS 5DS R:

• More detail: Has more megapixels (50.3 vs 11MP), which boosts linear resolution by 114%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Scores substantially higher (23 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (2.8 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (1.4 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (1.3 stops ISO advantage).
• Broader imaging potential: Can capture not only stills but also 1080/30p video.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.71x vs 0.70x).
• Larger screen: Has a bigger rear LCD (3.2" vs 2.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 120k dots).
• Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More compact: Is smaller (152x116mm vs 156x158mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 335g or 26 percent) and is thus easier to take along.
• Longer lasting: Gets more shots (700 versus 600) out of a single battery charge.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More affordable: Was introduced into a lower priced category (59 percent cheaper at launch).
• More modern: Reflects 12 years and 4 months of technical progress since the 1Ds launch.

If the count of individual advantages (bullet points above) is taken as a guide, the 5DS R is the clear winner of the contest (18 : 3 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.

How about other alternatives? Do the specifications of the Canon 1Ds and the Canon 5DS R place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 1Ds or the 5DS R. 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 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 above review scores should be interpreted 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
