Canon T7i vs Contax N Digital
The Canon EOS Rebel T7i (called Canon 800D in some regions) and the Contax N Digital are two digital cameras that were revealed to the public, respectively, in February 2017 and February 2002. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (T7i) and a full frame (N Digital) sensor. The Canon has a resolution of 24 megapixels, whereas the Contax provides 6.1 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS Rebel T7i and the Contax N Digital? 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.
The side-by-side display below illustrates the physical size and weight of the Canon T7i and the Contax N Digital. 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 dimensions are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Contax N Digital is considerably larger (60 percent) than the Canon T7i. Moreover, the N Digital is substantially heavier (86 percent) than the T7i. In this context, it is worth noting that neither the T7i nor the N Digital 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 T7i, there are third party battery grips available as optional accessories (see here on eBay).
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The T7i 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.
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. 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon T7i features an APS-C sensor and the Contax N Digital a full frame sensor. The sensor area in the N Digital is 160 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Despite having a smaller sensor, the Canon T7i offers a higher resolution of 24 megapixels, compared with 6.1 MP of the Contax 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 T7i is much more recent (by 14 years and 11 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 T7i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T7i 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 T7i has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS Rebel T7i has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 100-51200. The corresponding ISO settings for the Contax N Digital are ISO 50 to ISO 1600 (no boost).
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 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 T7i indeed provides movie recording capabilities, while the N Digital does not. The highest resolution format that the T7i can use is 1080/60p.
Apart from body and sensor, cameras can and do differ across a variety of features. The T7i and the N Digital 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 T7i (0.73x vs 0.51x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Canon T7i and Contax N Digital along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The T7i has one, while the N Digital does not. While the built-in flash of the T7i is not very powerful, it can at times be useful as a fill-in light.The T7i has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the N Digital does not have a selfie-screen.
The T7i writes its imaging data to SDXC cards, while the N Digital uses Compact Flash cards.
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 Canon EOS Rebel T7i and Contax N Digital and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

|Contax N Digital||Y||-||-||-||-||-||FW||-||-||-|
It is notable that the T7i offers wifi support, while the N Digital does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Studio photographers will appreciate that the Contax N Digital (unlike the T7i) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the T7i and the N Digital have been discontinued, but can regularly be found used on eBay. The T7i was replaced by the Canon T8i, 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 Canon and Contax websites.
So what is the bottom line? Is the Canon T7i better than the Contax N Digital or vice versa? A synthesis of the relative strong points of each of the models is listed below.

- More heavily discounted: Has been around for much longer (launched in February 2002).
If the count of relative strengths (bullet points above) is taken as a measure, the T7i is the clear winner of the match-up (18 : 6 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 Canon T7i and the Contax N Digital 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 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 T7i or the N Digital perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
