Body comparison

The side-by-side display below illustrates the physical size and weight of the Sony A7R III and the Canon 5DS. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.

Size Sony A7R III vs Canon 5DS
Compare A7R III versus 5DS top
Comparison A7R III or 5DS rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 5DS is considerably larger (45 percent) than the Sony A7R III. Moreover, the 5DS is substantially heavier (43 percent) than the A7R III. 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 compare the optics available for the two cameras in the Sony FE Lens Catalog (A7R III) and the Canon EF Lens Catalog (5DS). Mirrorless cameras, such as the Sony A7R III, 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 III gets 650 shots out of its Sony NP-FZ100 battery, while the 5DS can take 700 images on a single charge of its Canon LP-E6 power pack. The power pack in the A7R III can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

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 A7R III was launched at a somewhat lower price (by 14 percent) than the 5DS, 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

The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 are more costly to manufacture and tend to 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 III and Canon 5DS sensor measures

With 50.3MP, the 5DS offers a higher resolution than the A7R III (42.2MP), but the 5DS has smaller individual pixels (pixel pitch of 4.14μm versus 4.52μm for the A7R III). Yet, the A7R III is a much more recent model (by 2 years and 8 months) than the 5DS, and its sensor will 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 the A7R III has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Canon 5DS implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 5DS for good quality output (200 dots per inch) amounts to 43.4 x 29 inches or 110.3 x 73.6 cm, for very good quality (250 dpi) 34.8 x 23.2 inches or 88.3 x 58.8 cm, and for excellent quality (300 dpi) 29 x 19.3 inches or 73.6 x 49 cm. The corresponding values for the Sony A7R III are 39.8 x 26.5 inches or 101 x 67.4 cm for good quality, 31.8 x 21.2 inches or 80.8 x 53.9 cm for very good quality, and 26.5 x 17.7 inches or 67.3 x 44.9 cm for excellent quality prints.

The A7R III has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Unlike the 5DS, 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).

The Sony Alpha A7R III has a native sensitivity range from ISO 100 to ISO 32000, which can be extended to ISO 50-102400. The corresponding ISO settings for the Canon EOS 5DS are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 50-12800.

In terms of underlying technology, the A7R III is build around a BSI-CMOS sensor, while the 5DS uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

A7R III versus 5DS MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 review, the A7R III provides substantially higher image quality than the 5DS, with an overall score that is 13 points higher. This advantage is based on 1.3 bits higher color depth, 2.3 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 cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the A7R III provides a higher video resolution than the 5DS. It can shoot video footage at 4K/30p, while the Canon is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A7R III has an electronic viewfinder (3686k dots), while the 5DS 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 viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the A7R III has a higher magnification than the one of the 5DS (0.78x vs 0.71x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Sony A7R III and Canon 5DS in connection with corresponding information for a sample of similar cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One feature that differentiates the A7R III and the 5DS is in-body image stabilization (IBIS). The A7R III reduces the risk of handshake-induced blur with all attached lenses, while the 5DS offers no blur reduction with lenses that themselves do not provide optical image stabilization.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the A7R III is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Sony A7R III and the Canon 5DS both have an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

The A7R III writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the 5DS uses Compact Flash or SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails. The A7R III supports UHS-II cards (on its first slot), while the 5DS can use UHS-I cards.

It is notable that the A7R III has a headphone jack, which is not present on the 5DS This port makes it possible to attach external headphones and monitor the quality of sound during the recording process.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.

Both the A7R III and the 5DS have been discontinued, but can regularly be found used on ebay. The A7R III was replaced by the Sony A7R IV, while the 5DS does not have a direct successor. Further information on the features and operation of the A7R III and 5DS can be found, respectively, in the Sony A7R III Manual (free pdf) or the online Canon 5DS Manual.

  • More affordable: Was introduced into a lower priced segment (14 percent cheaper at launch).
  • More modern: Reflects 2 years and 8 months of technical progress since the 5DS launch.

ilogo

Reasons to prefer the Canon EOS 5DS:

  • More detail: Has more megapixels (50.3 vs 42.2MP), which boosts linear resolution by 9%.
  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • More heavily discounted: Has been around for much longer (launched in February 2015).

If the count of individual advantages (bullet points above) is taken as a guide, the A7R III is the clear winner of the match-up (27 : 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. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

How about other alternatives? Do the specifications of the Sony A7R III and the Canon 5DS place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the A7R III or the 5DS. 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.

Expert reviews

This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
