Canon 1D Mark II versus Sony A7R III

The Canon EOS-1D Mark II and the Sony Alpha A7R III are two digital cameras that were revealed to the public, respectively, in January 2004 and October 2017. The 1D Mark II is a DSLR, while the A7R III is a mirrorless interchangeable lens camera. The cameras are based on an APS-H (1D Mark II) and a full frame (A7R III) sensor. The Canon has a resolution of 8.2 megapixel, whereas the Sony provides 42.2 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 vs Sony A7R III

The physical size and weight of the Canon 1D Mark II and the Sony A7R III are illustrated in the side-by-side display below. 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 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 II – 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 A7R III is considerably smaller (51 percent) than the Canon 1D Mark II. Moreover, the A7R III is substantially lighter (58 percent) than the 1D Mark II. 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) and the Sony FE Lens Catalog (A7R III). Mirrorless cameras, such as the A7R III, 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 gets 1200 shots out of its NP-E3 battery, while the A7R III can take 650 images on a single charge of its NP-FZ100 power pack. As can be seen in the images above, the 1D Mark II has a battery grip build in. This facilitates image-taking in portrait orientation and contributes to its long-lasting power supply. In order to provide similar functionality for the A7R III, Sony provides the VG-C3EM vertical grip as an optional accessory (see here on eBay).

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

Any camera purchase will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The A7R III was launched at a markedly lower price (by 29 percent) than the 1D Mark II, 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: Canon 1D Mark II vs Sony A7R III

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. 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 tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 1D Mark II features an APS-H sensor and the Sony A7R III a full frame sensor. The sensor area in the A7R III is 57 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 and Sony A7R III sensor measures

With 42.2MP, the A7R III offers a higher resolution than the 1D Mark II (8.2MP), but the A7R III has smaller individual pixels (pixel pitch of 4.52μm versus 8.17μm for the 1D Mark II). Yet, the A7R III is a much more recent model (by 13 years and 8 months) than the 1D Mark II, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the A7R III has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

Unlike the 1D Mark II, the A7R III has the capacity to capture high quality composite images by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

1D Mark II versus A7R III MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 A7R III offers substantially better image quality than the 1D Mark II (overall score 34 points higher). The advantage is based on 3.7 bits higher color depth, 3.6 EV in additional dynamic range, and 1.8 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The A7R III indeed provides for movie recording, while the 1D Mark II does not. The highest resolution format that the A7R III can use is 4K/30p.

 

Feature comparison: Canon 1D Mark II vs Sony A7R III

Beyond body and sensor, cameras can and do differ across a range of features. For example, the A7R III has an electronic viewfinder (3686k dots), while the 1D Mark II 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 and Sony A7R III in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 1D Mark II, but is missing on the A7R III 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 reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the A7R III features an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

The A7R III is a current model that online retailers, such as amazon, will have in stock. In contrast, the 1D Mark II has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 1D Mark II was succeeded by the Canon 1D Mark II N.

Review summary: Canon 1D Mark II vs Sony A7R III

So how do things add up? Is there a clear favorite between the Canon 1D Mark II and the Sony A7R III? A synthesis of the relative strong points of each of the models is listed below.

  • 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.
  • Faster burst: Shoots at higher frequency (10 vs 8.3 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More compact: Is smaller (127x96mm vs 156x158mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 885g or 58 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 (29 percent cheaper at launch).
  • More modern: Reflects 13 years and 8 months of technical progress since the 1D Mark II launch.

If the count of relative strengths (bullet points above) is taken as a measure, the A7R III is the clear winner of the contest (21 : 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.

1D Mark II 06:21 A7R III

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the 1D Mark II and the A7R III 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 rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog). The detailed reviews can be accessed by clicking on the site logo in the table header.

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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
