Going beyond this snapshot of core features and characteristics, what are the differences between the Contax N Digital and the Olympus PEN E-PL7? 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 Contax N Digital and the Olympus E-PL7. 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 E-PL7 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 Olympus E-PL7 is considerably smaller (63 percent) than the Contax N Digital. Moreover, the E-PL7 is substantially lighter (64 percent) than the N Digital. In this context, it is worth noting that neither the N Digital nor the E-PL7 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.

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 obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-PL7 was launched at a markedly lower price (by 92 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.

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 are more costly to manufacture and tend to 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 Olympus E-PL7 a Four Thirds sensor. The sensor area in the E-PL7 is 74 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.0. The sensor in the N Digital has a native 3:2 aspect ratio, while the one in the E-PL7 offers a 4:3 aspect.

Despite having a smaller sensor, the E-PL7 offers a higher resolution of 15.9 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 3.76μm versus 11.90μm for the N Digital). However, it should be noted that the E-PL7 is much more recent (by 12 years and 6 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.

The resolution advantage of the Olympus E-PL7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-PL7 for good quality output (200 dots per inch) amounts to 23 x 17.3 inches or 58.5 x 43.9 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.8 x 35.1 cm, and for excellent quality (300 dpi) 15.4 x 11.5 inches or 39 x 29.3 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 Olympus PEN E-PL7 are ISO 200 to ISO 25600, 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 E-PL7 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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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.

Many modern cameras are not only capable of taking still images, but can also record movies. The E-PL7 indeed provides for movie recording, while the N Digital does not. The highest resolution format that the E-PL7 can use is 1080/30p.

Feature comparison

Apart from 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 E-PL7 relies on live view and the rear LCD for framing. That said, the E-PL7 can be equipped with an optional viewfinder – the VF-4. The table below summarizes some of the other core capabilities of the Contax N Digital and Olympus E-PL7 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 E-PL7 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 Olympus E-PL7 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 E-PL7 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 Olympus PEN E-PL7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-PL7 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the N Digital does not provide wifi capability.

Studio photographers will appreciate that the Contax N Digital (unlike the E-PL7) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the N Digital and the E-PL7 have been discontinued, but can regularly be found used on ebay. The E-PL7 was replaced by the Olympus E-PL8, 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 Olympus websites.

Review summary

So what is the bottom line? Is there a clear favorite between the Contax N Digital and the Olympus E-PL7? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Contax N Digital:

• 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 1/4000s) to freeze action.
• 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).

Reasons to prefer the Olympus PEN E-PL7:

• More detail: Has more megapixels (15.9 vs 6.1MP), which boosts linear resolution by 58%.
• 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 (1037k vs 200k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (8 vs 4 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More compact: Is smaller (115x67mm vs 152x138mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 633g or 64 percent) and is thus easier to take along.
• Longer lasting: Gets more shots (350 versus 100) out of a single battery charge.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• More legacy lens friendly: Can use many non-native lenses via adapters.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• More affordable: Was introduced into a lower priced category (92 percent cheaper at launch).
• More modern: Reflects 12 years and 6 months of technical progress since the N Digital launch.

If the count of relative strengths (bullet points above) is taken as a measure, the E-PL7 is the clear winner of the contest (17 : 6 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 Olympus E-PL7 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens 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 E-PL7 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 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 ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
