Body comparison

The side-by-side display below illustrates the physical size and weight of the Sony A7C and the Sony RX10 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 can be obtained in two different colors (black, silver), while the RX10 III is only available in black.

Comparison A7C or RX10 III rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony RX10 III is notably larger (42 percent) than the Sony A7C. 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 and possibly misleading, as the RX10 III has a lens built in, whereas the A7C is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the A7C and their specifications in the Sony FE Lens Catalog.

Concerning battery life, the A7C gets 740 shots out of its Sony NP-FZ100 battery, while the RX10 III can take 420 images on a single charge of its Sony NP-FW50 power pack. 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.

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 RX10 III was launched at a lower price than the A7C, despite having a lens built in. 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 imaging sensor is a crucial determinant 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Sony A7C features a full frame sensor and the Sony RX10 III an one-inch sensor. The sensor area in the RX10 III is 86 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sony A7C and Sony RX10 III sensor measures

With 24MP, the A7C offers a higher resolution than the RX10 III (20MP), but the A7C nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 2.41μm for the RX10 III) due to its larger sensor. Moreover, the A7C is a much more recent model (by 4 years and 5 months) than the RX10 III, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The resolution advantage of the Sony A7C implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7C for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Sony RX10 III are 27.4 x 18.2 inches or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inches or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inches or 46.3 x 30.9 cm for excellent quality prints.

The A7C has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Sony Alpha A7C 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 Cyber-shot DSC-RX10 III are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 64-25600.

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.

A7C versus RX10 III MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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 A7C provides substantially higher image quality than the RX10 III, with an overall score that is 25 points higher. This advantage is based on 1.9 bits higher color depth, 2.1 EV in additional dynamic range, and 2.9 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.

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

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The A7C has a touchscreen, while the RX10 III has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The A7C 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 RX10 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 has 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 and the RX10 III write their files to SDXC or Memory Stick PRO Duo cards. The A7C supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the RX10 III can use UHS-I cards (up to 104 MB/s).

Review summary

So how do things add up? Which of the two cameras – the Sony A7C or the Sony RX10 III – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.


Reasons to prefer the Sony Alpha A7C:

  • More detail: Offers more megapixels (24 vs 20MP) with a 10% higher linear resolution.
  • Better image quality: Scores substantially higher (25 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (1.9 bits more color depth).
  • More dynamic range: Captures a larger spectrum of light and dark details (2.1 EV of extra DR).
  • Better low-light sensitivity: Requires less light for good images (2.9 stops ISO advantage).
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
  • More compact: Is smaller (124x71mm vs 133x94mm) and thus needs less room in the bag.
  • Longer lasting: Can take more shots (740 versus 420) on a single battery charge.
  • Faster data transfer: Supports a more advanced USB protocol (3.2 vs 2.0).
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
  • More modern: Reflects 4 years and 5 months of technical progress since the RX10 III launch.


Arguments in favor of the Sony Cyber-shot DSC-RX10 III:

  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.59x).
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • More detailed LCD: Has a higher resolution rear screen (1229k vs 922k dots).
  • Faster burst: Shoots at higher frequency (14 vs 10 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Has an integrated lens, whereas the A7C necessitates an extra lens.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More heavily discounted: Has been around for much longer (launched in March 2016).

If the number of relative strengths (bullet points above) is taken as a guide, the A7C is the clear winner of the match-up (18 : 8 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.

A7C 18:08 RX10 III

How about other alternatives? Do the specifications of the Sony A7C and the Sony RX10 III place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Superzoom Camera listings 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 or the RX10 III perform in practice. 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 where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular 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 were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
