Canon 1D Mark IV versus Sony A7S II

The Canon EOS-1D Mark IV and the Sony Alpha 7S II are two professional cameras that were announced, respectively, in October 2009 and September 2015. The 1D Mark IV is a DSLR, while the A7S II is a mirrorless interchangeable lens camera. The cameras are based on an APS-H (1D Mark IV) and a full frame sensor. The Canon has a resolution of 16 megapixel, whereas the Sony provides 12 MP.

Body comparison

An illustration of the physical size and weight of the Canon 1D Mark IV and the Sony A7S II is provided 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. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the 1D Mark IV – represents the basis or 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 II is notably smaller (50 percent) than the Canon 1D Mark IV. Moreover, the A7S II is substantially lighter (49 percent) than the 1D Mark IV. 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 IV) and the Sony FE Lens Catalog (A7S II). Mirrorless cameras, such as the A7S II, 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.

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 comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The A7S II was launched at a markedly lower price (by 40 percent) than the 1D Mark IV, 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

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 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors are more costly to manufacture and tent to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 1D Mark IV features an APS-H sensor and the Sony A7S II a full frame sensor. The sensor area in the A7S II is 63 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.

Sensor size

Despite having a smaller sensor, the Canon 1D Mark IV offers a higher resolution of 16 megapixel, compared with 12 MP of the Sony A7S II. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 5.70μm versus 8.40μm for the A7S II). Moreover, it should be noted that the A7S II is much more recent (by 5 years and 10 months) than the 1D Mark IV, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

Sensor resolution

For most cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under consideration, the A7S II offers substantially better image quality than the 1D Mark IV (overall score 11 points higher). The advantage is based on 0.8 bits higher color depth, 1.3 EV in additional dynamic range, and 1.2 stops in additional low light sensitivity. 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. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the A7S II provides a better video resolution than the 1D Mark IV. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the A7S II has an electronic viewfinder (2400k dots), while the 1D Mark IV 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 IV and Sony A7S II in connection with corresponding information for a sample of similar cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

Reasons to prefer the Sony Alpha 7S II:

  • Better image quality: Scores substantially higher (11 points) in the DXO overall evaluation.
  • More dynamic range: Captures a broader range of light and dark details (1.3 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (1.2 stops ISO advantage).
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More detailed LCD: Has a higher resolution rear screen (1229k vs 920k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • More compact: Is smaller (127x96mm vs 156x157mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 603g or 49 percent) and is thus easier to take along.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More affordable: Was introduced into a lower priced category (40 percent cheaper at launch).
  • More modern: Reflects 5 years and 10 months of technical progress since the 1D Mark IV launch.

If the count of relative strengths (bullet points above) is taken as a measure, the A7S II is the clear winner of the contest (13 : 6 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.

1D Mark IV 06:13 A7S II

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 1D Mark IV or the A7S II. 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 why expert reviews are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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. 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.
