Going beyond this snapshot of core features and characteristics, what are the differences between the Contax N Digital and the Fujifilm X20? 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 Fujifilm X20 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.

The X20 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 Fujifilm X20 is considerably smaller (61 percent) than the Contax N Digital. In this context, it is worth noting that neither the N Digital nor the X20 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the X20 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.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The X20 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

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. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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.

Of the two cameras under consideration, the Contax N Digital features a full frame sensor and the Fujifilm X20 a 2/3 sensor. The sensor area in the X20 is 93 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 3.9. The sensor in the N Digital has a native 3:2 aspect ratio, while the one in the X20 offers a 4:3 aspect.

Despite having a smaller sensor, the X20 offers a higher resolution of 12 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 2.20μm versus 11.90μm for the N Digital). However, it should be noted that the X20 is much more recent (by 10 years and 10 months) 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 X20 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Fujifilm X20 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X20 for good quality output (200 dots per inch) amounts to 20 x 15 inches or 50.8 x 38.1 cm, for very good quality (250 dpi) 16 x 12 inches or 40.6 x 30.5 cm, and for excellent quality (300 dpi) 13.3 x 10 inches or 33.9 x 25.4 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 X20 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Contax N Digital has a native sensitivity range from ISO 50 to ISO 1600. The corresponding ISO settings for the Fujifilm X20 are ISO 100 to ISO 12800 (no boost).

In terms of underlying technology, the N Digital is build around a CCD sensor, while the X20 uses a CMOS imager. Like most digital cameras, the N Digital uses a Bayer filter for capturing RGB colors on a square grid of photosensors. In contrast, the X20 employs a more randomized X-Trans layout of photosites, which according to Fujifilm helps to minimize moiré.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. The X20 indeed provides for movie recording, while the N Digital does not. The highest resolution format that the X20 can use is 1080/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The N Digital and the X20 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 Contax N Digital and Fujifilm X20 along with similar information for a selection of comparators.

One feature that is present on the N Digital, but is missing on the X20 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 X20 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 Fujifilm X20 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 X20) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the N Digital and the X20 have been discontinued, but can regularly be found used on ebay. The X20 was replaced by the Fujifilm X30, 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 Fujifilm websites.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Contax N Digital and the Fujifilm X20? Which camera is better? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Contax N Digital:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
• Richer colors: The pixel size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
• 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.
• 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 Fujifilm X20:

• More detail: Has more megapixels (12 vs 6.1MP), which boosts linear resolution by 37%.
• 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 1080/60p video.
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Larger screen: Has a bigger rear LCD (2.8" vs 2.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (460k vs 200k dots).
• Faster burst: Shoots at higher frequency (12 vs 4 flaps/sec) to capture the decisive moment.
• Ready to shoot: Comes with an integrated lens, while the N Digital requires a separate lens.
• More compact: Is smaller (117x70mm 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 (270 versus 100) out of a single battery charge.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• 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 10 years and 10 months of technical progress since the N Digital launch.

If the count of relative strengths (bullet points above) is taken as a measure, the X20 is the clear winner of the contest (15 : 11 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. 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 Contax N Digital and the Fujifilm X20 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Travel-Zoom 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 says little about, for example, the shooting experience and imaging performance of the N Digital and the X20 in practical situations. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

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.

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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.
