Sony A7R II versus Canon 5DS R

The Sony Alpha A7R II and the Canon EOS 5DS R are two digital cameras that were officially introduced, respectively, in June 2015 and February 2015. The A7R II is a mirrorless interchangeable lens camera, while the 5DS R is a DSLR. Both cameras are equipped with a full frame sensor. The Sony has a resolution of 42.2 megapixel, whereas the Canon provides 50.3 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: Sony A7R II vs Canon 5DS R

The side-by-side display below illustrates the physical size and weight of the Sony A7R II and the Canon 5DS R. 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 width, height and depth dimensions are rounded to the nearest millimeter. You can also toggle the display 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 A7R 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 Canon 5DS R is considerably larger (45 percent) than the Sony A7R II. Moreover, the 5DS R is substantially heavier (49 percent) than the A7R 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. Both cameras have similarly sized sensors, but DSLRs have a larger flange-to-focal plane distance than mirrorless cameras, which imposes contraints on the optical engineering process and generally leads to bigger and heavier lenses. You can find an overview of optics for the two cameras in the Sony FE Lens Catalog (A7R II) and the Canon EF Lens Catalog (5DS R). Mirrorless cameras, such as the Sony A7R II, have moreover the advantage that they have a relatively short flange to focal plane distance and can thus use many lenses from other systems via adapters.

Concerning battery life, the A7R II gets 290 shots out of its NP-FW50 battery, while the 5DS R can take 700 images on a single charge of its LP-E6 power pack.

The camera’s price is obviously a critical decision-making factor. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The A7R II was launched at a somewhat lower price (by 14 percent) than the 5DS R, which makes it more attractive for photographers on a tight budget. 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: Sony A7R II vs Canon 5DS R

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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature a full frame sensor, but their sensors differ slightly in size. They nevertheless have the same format factor of 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sony A7R II and Canon 5DS R sensor measures

With 50.3MP, the 5DS R offers a higher resolution than the A7R II (42.2MP), but the 5DS R has smaller individual pixels (pixel pitch of 4.14μm versus 4.52μm for the A7R II). It is noteworthy in this context that the A7R II is a somewhat more recent model (by 4 months) than the 5DS R, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

A7R II versus 5DS R MP

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"). Of the two cameras under review, the A7R II provides substantially higher image quality than the 5DS R, with an overall score that is 12 points higher. This advantage is based on 1.4 bits higher color depth, 1.5 EV in additional dynamic range, and 0.6 stops in additional low light sensitivity. 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. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the A7R II provides a higher video resolution than the 5DS R. It can shoot video footage at 4K/30p, while the Canon is limited to 1080/60p.

 

Feature comparison: Sony A7R II vs Canon 5DS R

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A7R II has an electronic viewfinder (2400k dots), while the 5DS R 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 following table reports on some other key feature differences and similarities of the Sony A7R II, the Canon 5DS R, and comparable cameras.

One feature that differentiates the A7R II and the 5DS R is in-body image stabilization (IBIS). The A7R II reduces the risk of handshake-induced blur with all attached lenses, while the 5DS R has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

The A7R II writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the 5DS R uses Compact Flash or SDXC cards. The 5DS R features dual card slots, which can be very useful in case a memory card fails. In contrast, the A7R II only has one slot.

If the count of individual advantages (bullet points above) is taken as a guide, the A7R II is the clear winner of the match-up (17 : 8 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.

A7R II 17:08 5DS R

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 A7R II and the 5DS R in practical situations. 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 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 review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, 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.
