Going beyond this snapshot of core features and characteristics, what are the differences between the Contax N Digital and the Nikon Coolpix A? 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 Contax N Digital and the Nikon Coolpix A 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 Coolpix A can be obtained in two different colors (black, silver), while the N Digital is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon Coolpix A is considerably smaller (66 percent) than the Contax N Digital. In this context, it is worth noting that neither the N Digital nor the Coolpix A are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the Coolpix A has a lens built in, whereas the N Digital is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.

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.

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 Coolpix A was launched at a lower price than the N Digital, despite having a lens built in. 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. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Contax N Digital features a full frame sensor and the Nikon Coolpix A an APS-C sensor. The sensor area in the Coolpix A 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.

Despite having a smaller sensor, the Coolpix A offers a higher resolution of 16.1 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 4.78μm versus 11.90μm for the N Digital). However, it should be noted that the Coolpix A is much more recent (by 11 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. Coming back to sensor resolution, it should be mentioned that the Coolpix A has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Nikon Coolpix A implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Coolpix A for good quality output (200 dots per inch) amounts to 24.6 x 16.3 inches or 62.6 x 41.5 cm, for very good quality (250 dpi) 19.7 x 13.1 inches or 50.1 x 33.2 cm, and for excellent quality (300 dpi) 16.4 x 10.9 inches or 41.7 x 27.6 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 Coolpix A are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-25600.

In terms of underlying technology, the N Digital is build around a CCD sensor, while the Coolpix A uses a CMOS 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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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 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 Coolpix A indeed provides for movie recording, while the N Digital does not. The highest resolution format that the Coolpix A can use is 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the N Digital has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the Coolpix A relies on live view and the rear LCD for framing. That said, the Coolpix A can be equipped with an optional viewfinder – the DF-CP1. The table below summarizes some of the other core capabilities of the Contax N Digital and Nikon Coolpix A in connection with corresponding information for a sample of similar cameras.

One feature that is present on the N Digital, but is missing on the Coolpix A 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 Nikon Coolpix A 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 N Digital writes its imaging data to Compact Flash cards, while the Coolpix A uses SDXC cards.

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 Contax N Digital and Nikon Coolpix A and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

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

Both the N Digital and the Coolpix A have been discontinued, but can regularly be found used on ebay. Neither of the two has a direct successor, so they represent the end of the respective camera lines from Contax and Nikon. 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 is the bottom line? Which of the two cameras – the Contax N Digital or the Nikon Coolpix A – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Contax N Digital:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Easier framing: Has an optical viewfinder for image composition and settings control.
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/2000s) to freeze action.
• More flexible: Can take a variety of interchangeable lenses, including specialty optics.
• 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).

Advantages of the Nikon Coolpix A:

• More detail: Has more megapixels (16.1 vs 6.1MP), which boosts linear resolution by 62%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Broader imaging potential: Can capture not only stills but also 1080/30p video.
• 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 200k dots).
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Ready to shoot: Comes with an integrated lens, while the N Digital requires a separate lens.
• More compact: Is smaller (111x64mm vs 152x138mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the N Digital).
• Longer lasting: Gets more shots (230 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 at a lower price, despite coming with a built-in lens.
• More modern: Reflects 11 years of technical progress since the N Digital launch.

If the number of relative strengths (bullet points above) is taken as a guide, the Coolpix A is the clear winner of the contest (13 : 8 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 Contax N Digital and the Nikon Coolpix A place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Prime Lens Compact Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the N Digital or the Coolpix A 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.

Expert reviews

This is where reviews by experts come in. 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 ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
