Canon 1D Mark II N versus Sony A7S

The Canon EOS-1D Mark II N and the Sony Alpha A7S are two professional cameras that were revealed to the public, respectively, in August 2005 and April 2014. The 1D Mark II N is a DSLR, while the A7S is a mirrorless interchangeable lens camera. The cameras are based on an APS-H (1D Mark II N) and a full frame (A7S) sensor. The Canon has a resolution of 8.2 megapixel, whereas the Sony provides 12 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon 1D Mark II N vs Sony A7S

The physical size and weight of the Canon 1D Mark II N and the Sony A7S are illustrated in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth measures are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the 1D Mark II N – represents 100 percent across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A7S is considerably smaller (52 percent) than the Canon 1D Mark II N. Moreover, the A7S is substantially lighter (69 percent) than the 1D Mark II N. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can find an overview of optics for the two cameras in the Canon EF Lens Catalog (1D Mark II N) and the Sony FE Lens Catalog (A7S). Mirrorless cameras, such as the A7S, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.

Concerning battery life, the 1D Mark II N gets 1200 shots out of its NP-E3 battery, while the A7S can take 380 images on a single charge of its NP-FW50 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

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 A7S was launched at a markedly lower price (by 38 percent) than the 1D Mark II N, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison: Canon 1D Mark II N vs Sony A7S

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 1D Mark II N features an APS-H sensor and the Sony A7S a full frame sensor. The sensor area in the A7S is 56 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon 1D Mark II N and Sony A7S sensor measures

With 12MP, the A7S offers a higher resolution than the 1D Mark II N (8.2MP), but the A7S nevertheless has larger individual pixels (pixel pitch of 8.45μm versus 8.17μm for the 1D Mark II N) due to its larger sensor. Moreover, the A7S is a much more recent model (by 8 years and 7 months) than the 1D Mark II N, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

1D Mark II N versus A7S MP

For most 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. Of the two cameras under consideration, the A7S offers substantially better image quality than the 1D Mark II N (overall score 21 points higher). The advantage is based on 1.6 bits higher color depth, 2 EV in additional dynamic range, and 1.9 stops in additional low light sensitivity.

Many modern cameras cannot only take still pictures, but also record videos. The A7S indeed provides for movie recording, while the 1D Mark II N does not. The highest resolution format that the A7S can use is 1080/60p.

Feature comparison: Canon 1D Mark II N vs Sony A7S

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A7S has an electronic viewfinder (2400k dots), while the 1D Mark II N has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The table below summarizes some of the other core capabilities of the Canon 1D Mark II N and Sony A7S in connection with corresponding information for a sample of similar cameras.

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 1D Mark II N or the A7S. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is where reviews by experts come in. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Care should be taken when interpreting the review scores above, 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 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.
