Body comparison

The side-by-side display below illustrates the physical size and weight of the Sony A7C II and the Sony A7R III. 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.

The A7C II can be obtained in two different colors (black, silver), while the A7R III is only available in black.

Compare A7C II versus A7R III top
Comparison A7C II or A7R III rear

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 notably larger (38 percent) than the Sony A7C II. Moreover, the A7R III is markedly heavier (26 percent) than the A7C 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Sony FE Lens Catalog. Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.

The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will naturally be influenced heavily by the price. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The A7C II was launched at a markedly lower price (by 31 percent) than the A7R III, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 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.

In terms of chip-set technology, the A7C II uses a more advanced image processing engine (BIONZ XR) than the A7R III (BIONZ X), with benefits for noise reduction, color accuracy, and processing speed.

Sony A7C II and Sony A7R III sensor measures

With 42.2MP, the A7R III offers a higher resolution than the A7C II (32.7MP), but the A7R III has smaller individual pixels (pixel pitch of 4.52μm versus 5.12μm for the A7C II). Yet, the A7C II is a much more recent model (by 5 years and 10 months) than the A7R III, 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The resolution advantage of the Sony A7R III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7R III for good quality output (200 dots per inch) amounts to 39.8 x 26.5 inches or 101 x 67.4 cm, for very good quality (250 dpi) 31.8 x 21.2 inches or 80.8 x 53.9 cm, and for excellent quality (300 dpi) 26.5 x 17.7 inches or 67.3 x 44.9 cm. The corresponding values for the Sony A7C II are 35 x 23.4 inches or 89 x 59.3 cm for good quality, 28 x 18.7 inches or 71.2 x 47.5 cm for very good quality, and 23.4 x 15.6 inches or 59.3 x 39.6 cm for excellent quality prints.

Unlike the A7C 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).

The Sony Alpha A7C II has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 50-204800. The corresponding ISO settings for the Sony Alpha A7R III are ISO 100 to ISO 32000, with the possibility to increase the ISO range to 50-102400.

Technology-wise, both cameras are equipped with BSI-CMOS (Backside Illuminated Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.
The A7C II has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the A7R III does not have a selfie-screen.

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, both cameras under consideration feature an 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 A7C II and the Sony A7R III 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.

Concerning the storage of imaging data, both the A7C II and the A7R III write their files to SDXC or Memory Stick PRO Duo cards. The A7R III features dual card slots, which can be very useful in case a memory card fails. In contrast, the A7C II only has one slot. Both the A7C II and the A7R III support UHS-II cards, which provide for Ultra High Speed data transfer of up to 312 MB/s (the second slot of the A7R III only offers slower UHS-I transfer rates, though).

Studio photographers will appreciate that the Sony A7R III (unlike the A7C II) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The A7C II is a recent model that features in the current product line-up of Sony. In contrast, the A7R III has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the A7R III was succeeded by the Sony A7R IV. Further information on the features and operation of the A7C II and A7R III can be found, respectively, in the Sony A7C II Manual (free pdf) or the online Sony A7R III Manual.

Review summary

So how do things add up? Which of the two cameras – the Sony A7C II or the Sony A7R III – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.


Arguments in favor of the Sony Alpha A7C II:

  • Better jpgs: Has a more modern image processing engine (BIONZ XR vs BIONZ X).
  • Better video: Provides higher movie framerates (4K/60p versus 4K/30p).
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • More compact: Is smaller (124x71mm vs 127x96mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 136g or 21 percent) and hence easier to carry around.
  • Faster data transfer: Supports a more advanced USB protocol (3.2 vs 3.1).
  • More affordable: Was introduced into a lower priced category (31 percent cheaper at launch).
  • More modern: Reflects 5 years and 10 months of technical progress since the A7R III launch.


Reasons to prefer the Sony Alpha A7R III:

  • More detail: Has more megapixels (42.2 vs 32.7MP), which boosts linear resolution by 13%.
  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (3686k vs 2360k dots).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.78x vs 0.7x).
  • More detailed LCD: Has a higher resolution rear screen (1440k vs 1037k dots).
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Longer lasting: Gets more shots (650 versus 540) out of a single battery charge.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More heavily discounted: Has been around for much longer (launched in October 2017).

If the count of relative strengths (bullet points above) is taken as a measure, the A7R III emerges as the winner of the match-up (11 : 9 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. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

A7C II 09:11 A7R III

How about other alternatives? Do the specifications of the Sony A7C II and the Sony A7R III place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the A7C II or the A7R III perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

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.

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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
