Contax N Digital vs Nikon D40X

The Contax N Digital and the Nikon D40X are two digital cameras that were announced, respectively, in February 2002 and March 2007. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (N Digital) and an APS-C (D40X) sensor. The Contax has a resolution of 6.1 megapixels, whereas the Nikon provides 10 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Body comparison

The physical size and weight of the Contax N Digital and the Nikon D40X 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.

The D40X can be obtained in two different colors (black, silver), while the N Digital is only available in black.

Size Contax N Digital vs Nikon D40X
Compare N Digital versus D40X top
Comparison N Digital or D40X rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D40X is considerably smaller (44 percent) than the Contax N Digital. Moreover, the D40X is substantially lighter (47 percent) than the N Digital. In this context, it is worth noting that neither the N Digital nor the D40X are weather-sealed.

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 D40X, there are third party battery grips available as optional accessories (see here on ebay).

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

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 D40X was launched at a markedly lower price (by 90 percent) than the N Digital, 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.

Of the two cameras under consideration, the Contax N Digital features a full frame sensor and the Nikon D40X an APS-C sensor. The sensor area in the D40X is 57 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Contax N Digital and Nikon D40X sensor measures

Despite having a smaller sensor, the D40X offers a higher resolution of 10 megapixels, compared with 6.1 MP of the N Digital. 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 6.11μm versus 11.90μm for the N Digital). However, it should be noted that the D40X is much more recent (by 5 years) than the N Digital, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Nikon D40X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D40X for good quality output (200 dots per inch) amounts to 19.4 x 13 inches or 49.2 x 32.9 cm, for very good quality (250 dpi) 15.5 x 10.4 inches or 39.3 x 26.3 cm, and for excellent quality (300 dpi) 12.9 x 8.6 inches or 32.8 x 21.9 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 Contax N Digital has a native sensitivity range from ISO 50 to ISO 1600. The corresponding ISO settings for the Nikon D40X are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 100-3200.

Technology-wise, both cameras are equipped with CCD (Charged Coupled Device) 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.

N Digital versus D40X MP

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"). The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The N Digital and the D40X 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 (95%), but the viewfinder of the N Digital has a higher magnification than the one of the D40X (0.73x vs 0.53x), 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 Contax N Digital, the Nikon D40X, and comparable cameras.

One feature that is present on the N Digital, but is missing on the D40X is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The N Digital writes its imaging data to Compact Flash cards, while the D40X uses SDHC cards.

Studio photographers will appreciate that the Contax N Digital (unlike the D40X) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the N Digital and the D40X have been discontinued, but can regularly be found used on ebay. The D40X was replaced by the Nikon D60 , 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 Contax and Nikon websites.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Contax N Digital and the Nikon D40X? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Reasons to prefer the Contax N Digital:

  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.73x vs 0.53x).
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • 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.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • More heavily discounted: Has been available for much longer (launched in February 2002).

ilogo

Arguments in favor of the Nikon D40X:

  • More detail: Has more megapixels (10 vs 6.1MP), which boosts linear resolution by 28%.
  • 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 (124x94mm vs 152x138mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 468g or 47 percent) and is thus easier to take along.
  • Longer lasting: Gets more shots (520 versus 100) out of a single battery charge.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (90 percent cheaper at launch).
  • More modern: Reflects 5 years of technical progress since the N Digital launch.

If the count of individual advantages (bullet points above) is taken as a guide, the D40X emerges as the winner of the match-up (9 : 7 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.

N Digital 07:09 D40X

How about other alternatives? Do the specifications of the Contax N Digital and the Nikon D40X 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 N Digital or the D40X. 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.

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 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.
