Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 5D and the Contax N Digital? 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 5D and the Contax N Digital. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. 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 Contax N Digital is notably larger (22 percent) than the Canon 5D. Moreover, the N Digital is markedly heavier (11 percent) than the 5D. It is worth mentioning in this context that the 5D is splash and dust resistant, while the N Digital does not feature any corresponding weather-sealing.

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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

As can be seen in the images above, the N Digital 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 5D, Canon provides the BG-E4 vertical grip as an optional accessory (see here on ebay).

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The 5D was launched at a markedly lower price (by 55 percent) than the N Digital, 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

The size of the sensor inside a digital camera is one of the key determinants 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 more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature a full frame sensor and have a format factor (sometimes also referred to as "crop factor") of 1.0. Within the spectrum of camera sensors, this places the review cameras among the large-sensor cameras that aim for top notch image quality. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

While the two cameras under review share the same sensor size, the 5D offers a higher resolution of 12.7 megapixels, compared with 6.1 MP of the N Digital. This megapixels advantage translates into a 44 percent gain in linear resolution. On the other hand, these sensor specs imply that the 5D has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 8.25μm versus 11.90μm for the N Digital). In this context, it should be noted, however, that the 5D is much more recent (by 3 years and 5 months) than the N Digital, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.

The resolution advantage of the Canon 5D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 5D for good quality output (200 dots per inch) amounts to 21.8 x 14.6 inches or 55.5 x 37 cm, for very good quality (250 dpi) 17.5 x 11.6 inches or 44.4 x 29.6 cm, and for excellent quality (300 dpi) 14.6 x 9.7 inches or 37 x 24.7 cm. The corresponding values for the Contax N Digital are 15.2 x 10 inches or 38.6 x 25.5 cm for good quality, 12.2 x 8 inches or 30.9 x 20.4 cm for very good quality, and 10.1 x 6.7 inches or 25.7 x 17 cm for excellent quality prints.

The Canon EOS 5D has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 50-3200. The corresponding ISO settings for the Contax N Digital are ISO 50 to ISO 1600 (no boost).

In terms of underlying technology, the 5D is build around a CMOS sensor, while the N Digital 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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The 5D and the N Digital 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 viewfinder in the 5D offers a wider field of view (96%) than the one in the N Digital (95%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the N Digital has a higher magnification (0.73x vs 0.71x), 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 Canon 5D and Contax N Digital along with similar information for a selection of comparators.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.

Both the 5D and the N Digital have been discontinued, but can regularly be found used on ebay. The 5D was replaced by the Canon 5D Mark II, while the N Digital 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 Contax websites.

Review summary

So how do things add up? Which of the two cameras – the Canon 5D or the Contax N Digital – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Canon EOS 5D:

• More detail: Offers more megapixels (12.7 vs 6.1MP) with a 44% higher linear resolution.
• More complete view: Has a viewfinder with a larger field of view (96% vs 95%).
• Larger screen: Has a bigger rear LCD (2.5" vs 2.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (230k vs 200k dots).
• More compact: Is smaller (152x113mm vs 152x138mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 95g or 10 percent) and hence easier to carry around.
• Longer lasting: Can take more shots (400 versus 100) on a single battery charge.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• More affordable: Was introduced into a lower priced category (55 percent cheaper at launch).
• More modern: Reflects 3 years and 5 months of technical progress since the N Digital launch.

Advantages of the Contax N Digital:

• Larger viewfinder image: Features a viewfinder with a higher magnification (0.73x vs 0.71x).
• Faster burst: Shoots at higher frequency (4 vs 3 flaps/sec) to capture the decisive moment.
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• More heavily discounted: Has been around for much longer (launched in February 2002).

If the count of relative strengths (bullet points above) is taken as a measure, the 5D is the clear winner of the match-up (10 : 4 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. 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.

How about other alternatives? Do the specifications of the Canon 5D and the Contax N Digital 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 5D or the N Digital. 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 expert reviews 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.

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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
