Going beyond this snapshot of core features and characteristics, what are the differences between the Contax N Digital and the Canon EOS M100? 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 Canon M100. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

The M100 can be obtained in two different colors (black, white), 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 Canon M100 is considerably smaller (66 percent) than the Contax N Digital. Moreover, the M100 is substantially lighter (69 percent) than the N Digital. In this context, it is worth noting that neither the N Digital nor the M100 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 adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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 obviously take relative prices into account. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The M100 was launched at a markedly lower price (by 93 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 sensor inside a digital camera is one of the key determinants 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. 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 Canon M100 an APS-C sensor. The sensor area in the M100 is 62 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Despite having a smaller sensor, the M100 offers a higher resolution of 24 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 3.72μm versus 11.90μm for the N Digital). However, it should be noted that the M100 is much more recent (by 15 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 Canon M100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M100 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 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 M100 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 Canon EOS M100 are ISO 100 to ISO 25600 (no boost).

In terms of underlying technology, the N Digital is build around a CCD sensor, while the M100 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 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 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 M100 indeed provides for movie recording, while the N Digital does not. The highest resolution format that the M100 can use is 1080/60p.

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 M100 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Contax N Digital and Canon M100 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 M100 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 M100 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 Canon EOS M100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the N Digital has a hotshoe, while the M100 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Studio photographers will appreciate that the Contax N Digital (unlike the M100) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the N Digital and the M100 have been discontinued, but can regularly be found used on ebay. The M100 was replaced by the Canon M200, 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 Canon websites.

Review summary

So what conclusions can be drawn? Is the Contax N Digital better than the Canon M100 or vice versa? The listing below highlights the relative strengths of the two models.

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 lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• 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 Canon EOS M100:

• More detail: Has more megapixels (24 vs 6.1MP), which boosts linear resolution by 98%.
• 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 (3.0" vs 2.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k 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 (6.1 vs 4 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (108x67mm vs 152x138mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 688g or 69 percent) and is thus easier to take along.
• Longer lasting: Gets more shots (295 versus 100) out of a single battery charge.
• More legacy lens friendly: Can use many non-native lenses via adapters.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More affordable: Was introduced into a lower priced category (93 percent cheaper at launch).
• More modern: Reflects 15 years and 6 months of technical progress since the N Digital launch.

If the number of relative strengths (bullet points above) is taken as a guide, the M100 is the clear winner of the contest (19 : 7 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 Canon M100 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the N Digital or the M100 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 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.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
