Canon SX620 vs Contax N Digital
The Canon PowerShot SX620 HS and the Contax N Digital are two digital cameras that were announced, respectively, in May 2016 and February 2002. The SX620 is a fixed lens compact, while the N Digital is a DSLR. The cameras are based on a 1/2.3-inch (SX620) and a full frame (N Digital) sensor. The Canon has a resolution of 20.2 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 PowerShot SX620 HS 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 SX620 and the Contax N Digital. 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 SX620 can be obtained in three different colors (black, silver, red), 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 Contax N Digital is considerably larger (279 percent) than the Canon SX620. In this context, it is worth noting that neither the SX620 nor the N Digital are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX620 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 following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

The price is, of course, an important factor in any camera decision. 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 SX620 was launched at a lower price than the N Digital, despite having a lens built in. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The size of the sensor inside a digital camera is one of the key determinants 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon SX620 features a 1/2.3-inch sensor and the Contax N Digital a full frame sensor. The sensor area in the N Digital is 2986 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.0. The sensor in the SX620 has a native 4:3 aspect ratio, while the one in the N Digital offers a 3:2 aspect.
Despite having a smaller sensor, the Canon SX620 offers a higher resolution of 20.2 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 1.18μm versus 11.90μm for the N Digital). However, it should be noted that the SX620 is much more recent (by 14 years and 2 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 SX620 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Canon SX620 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SX620 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 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 Canon PowerShot SX620 HS has a native sensitivity range from ISO 80 to ISO 3200. The corresponding ISO settings for the Contax N Digital are ISO 50 to ISO 1600 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 also of capturing video footage. The SX620 indeed provides movie recording capabilities, while the N Digital does not. The highest resolution format that the SX620 can use is 1080/30p.
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 SX620 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon SX620 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 SX620 has one, while the N Digital does not. While the built-in flash of the SX620 is not very powerful, it can at times be useful as a fill-in light.
The SX620 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 PowerShot SX620 HS and Contax N Digital and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SX620 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 SX620) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The SX620 is a recent model that features in the current product line-up of Canon. In contrast, the N Digital has been discontinued (but can be found pre-owned on eBay). There has not been a direct replacement model for the N Digital from Contax. 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? Which of the two cameras – the Canon SX620 or the Contax N Digital – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

If the number of relative strengths (bullet points above) is taken as a guide, the SX620 comes out slightly ahead of the N Digital (15 : 14 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 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.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the SX620 and the N Digital 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.
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], 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 assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
