Canon 1Ds Mark III versus Nikon D3S

The Canon EOS-1Ds Mark III and the Nikon D3S are two professional cameras that were revealed to the public, respectively, in August 2007 and October 2009. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with a full frame sensor. The Canon has a resolution of 21 megapixel, whereas the Nikon provides 12.1 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon 1Ds Mark III vs Nikon D3S

An illustration of the physical size and weight of the Canon 1Ds Mark III and the Nikon D3S 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 width, height and depth dimensions are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left side – the 1Ds Mark III – represents the basis for the calculations across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D3S is somewhat larger (5 percent) than the Canon 1Ds Mark III. However, the D3S is markedly lighter (10 percent) than the 1Ds Mark III. 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. Yet, since both cameras are based around a full frame sensor, their respective lenses will tend to have similar dimensions and heft. You can find an overview of optics for the two cameras in the Canon EF Lens Catalog (1Ds Mark III) and the Nikon Lens Catalog (D3S).

Concerning battery life, the 1Ds Mark III gets 1800 shots out of its LP-E4 battery, while the D3S can take 4200 images on a single charge of its EN-EL4a power pack. As can be seen in the images above, both cameras have a battery grip build in. This facilitates image-taking in portrait orientation and gives it additional battery power.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The camera’s price is obviously a critical decision-making factor. 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 D3S was launched at a markedly lower price (by 35 percent) than the 1Ds Mark III, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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: Canon 1Ds Mark III vs Nikon D3S

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. 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 a full frame sensor, but their sensors differ slightly in size. 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.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

With 21MP, the 1Ds Mark III offers a higher resolution than the D3S (12.1MP), but the 1Ds Mark III has smaller individual pixels (pixel pitch of 6.41μm versus 8.43μm for the D3S). Moreover, the D3S is a somewhat more recent model (by 2 years and 1 month) than the 1Ds Mark III, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.

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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The D3S indeed provides for movie recording, while the 1Ds Mark III does not. The highest resolution format that the D3S can use is 720/24p.

Feature comparison: Canon 1Ds Mark III vs Nikon D3S

Apart from body and sensor, cameras can and do differ across a range of features. The 1Ds Mark III and the D3S 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 1Ds Mark III and Nikon D3S along with similar information for a selection of comparators. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

Both the 1Ds Mark III and the D3S write their imaging data to Compact Flash cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.

Both the 1Ds Mark III and the D3S have been discontinued, but can regularly be found used on eBay. The 1Ds Mark III was replaced by the Canon 1DX, while the D3S was followed by the Nikon D4.

Review summary: Canon 1Ds Mark III vs Nikon D3S

So how do things add up? Is there a clear favorite between the Canon 1Ds Mark III and the Nikon D3S? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Canon EOS-1Ds Mark III:

• More detail: Offers more megapixels (21 vs 12.1MP) with a 32% higher linear resolution.
• More heavily discounted: Has been available for much longer (launched in August 2007).

Advantages of the Nikon D3S:

• Better low-light sensitivity: Can shoot in dim conditions (1 stops ISO advantage).
• Broader imaging potential: Can capture not only stills but also 720/24p video.
• More detailed LCD: Has a higher resolution rear screen (921k vs 230k dots).
• Faster burst: Shoots at higher frequency (11 vs 5 flaps/sec) to capture the decisive moment.
• Longer lasting: Gets more shots (4200 versus 1800) out of a single battery charge.
• More affordable: Was introduced into a lower priced category (35 percent cheaper at launch).
• More modern: Reflects 2 years and 1 month of technical progress since the 1Ds Mark III launch.

If the count of individual advantages (bullet points above) is taken as a guide, the D3S is the clear winner of the contest (7 : 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.

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the 1Ds Mark III or the D3S handle or 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. This is why hands-on reviews by experts are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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. 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.
