Nikon D3S vs Canon 1D Mark II

The Nikon D3S and the Canon EOS-1D Mark II are two professional cameras that were revealed to the public, respectively, in October 2009 and January 2004. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (D3S) and an APS-H (1D Mark II) sensor. The Nikon has a resolution of 12.1 megapixels, whereas the Canon provides 8.2 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 Nikon D3S and the Canon EOS-1D Mark II? 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 Nikon D3S and the Canon 1D Mark II 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.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 1D Mark II is somewhat smaller (2 percent) than the Nikon D3S. However, the 1D Mark II is markedly heavier (24 percent) than the D3S. 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Nikon Lens Catalog (D3S) and the Canon EF Lens Catalog (1D Mark II).

Concerning battery life, the D3S gets 4200 shots out of its Nikon EN-EL4a battery, while the 1D Mark II can take 1200 images on a single charge of its Canon NP-E3 power pack. As can be seen in the images above, both cameras have a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power.

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 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 1D Mark II was launched at a somewhat lower price (by 13 percent) than the D3S, which makes it more attractive for photographers on a tight budget. 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Nikon D3S features a full frame sensor and the Canon 1D Mark II an APS-H sensor. The sensor area in the 1D Mark II is 36 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.3. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 12.1MP, the D3S offers a higher resolution than the 1D Mark II (8.2MP), but the D3S nevertheless has larger individual pixels (pixel pitch of 8.43μm versus 8.17μm for the 1D Mark II) due to its larger sensor. Moreover, the D3S is a much more recent model (by 5 years and 8 months) than the 1D Mark II, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The resolution advantage of the Nikon D3S implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D3S for good quality output (200 dots per inch) amounts to 21.3 x 14.2 inches or 54.1 x 36 cm, for very good quality (250 dpi) 17 x 11.3 inches or 43.2 x 28.8 cm, and for excellent quality (300 dpi) 14.2 x 9.4 inches or 36 x 24 cm. The corresponding values for the Canon 1D Mark II are 17.5 x 11.7 inches or 44.5 x 29.7 cm for good quality, 14 x 9.3 inches or 35.6 x 23.7 cm for very good quality, and 11.7 x 7.8 inches or 29.7 x 19.8 cm for excellent quality prints.

The Nikon D3S has a native sensitivity range from ISO 200 to ISO 12800, which can be extended to ISO 100-102400. The corresponding ISO settings for the Canon EOS-1D Mark II are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 50-3200.

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.

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. Of the two cameras under review, the D3S provides substantially higher image quality than the 1D Mark II, with an overall score that is 16 points higher. This advantage is based on 1.2 bits higher color depth, 0.9 EV in additional dynamic range, and 1.7 stops in additional low light sensitivity. 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 also of capturing video footage. The D3S indeed provides movie recording capabilities, while the 1D Mark II does not. The highest resolution format that the D3S can use is 720/24p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The D3S and the 1D Mark II 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 D3S has a higher magnification than the one of the 1D Mark II (0.70x vs 0.55x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Nikon D3S and Canon 1D Mark II along with similar information for a selection of comparators.

The Nikon D3S 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 D3S writes its imaging data to Compact Flash cards, while the 1D Mark II uses Compact Flash or SD cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.

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 Nikon D3S and Canon EOS-1D Mark II 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 D3S and the 1D Mark II have been discontinued, but can regularly be found used on ebay. The 1D Mark II was replaced by the Canon 1D Mark II N, while the D3S was followed by the Nikon D4. Further information on the features and operation of the D3S and 1D Mark II can be found, respectively, in the Nikon D3S Manual (free pdf) or the online Canon 1D Mark II Manual.

Review summary

So what is the bottom line? Is the Nikon D3S better than the Canon 1D Mark II or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Nikon D3S:

• More detail: Offers more megapixels (12.1 vs 8.2MP) with a 21% higher linear resolution.
• Better image quality: Scores substantially higher (16 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (1.2 bits more color depth).
• More dynamic range: Captures a larger spectrum of light and dark details (0.9 EV of extra DR).
• Better low-light sensitivity: Requires less light for good images (1.7 stops ISO advantage).
• Broader imaging potential: Can record not only still images but also 720/24p movies.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.55x).
• 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 (921k vs 230k dots).
• Faster burst: Shoots at higher frequency (11 vs 8.3 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Less heavy: Is lighter (by 295g or 19 percent) and hence easier to carry around.
• Longer lasting: Can take more shots (4200 versus 1200) on a single battery charge.
• Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
• More modern: Reflects 5 years and 8 months of technical progress since the 1D Mark II launch.

Advantages of the Canon EOS-1D Mark II:

• More affordable: Was released into a lower priced segment (13 percent cheaper at launch).
• More heavily discounted: Has been around for much longer (launched in January 2004).

If the count of relative strengths (bullet points above) is taken as a measure, the D3S is the clear winner of the match-up (15 : 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.

How about other alternatives? Do the specifications of the Nikon D3S and the Canon 1D Mark II 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 incomplete and does no justice, for example, to the way the D3S or the 1D Mark II 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 why hands-on reviews by experts are important. 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.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
