Sony RX1 vs A7R III
The Sony Cyber-shot DSC-RX1 and the Sony Alpha A7R III are two enthusiast cameras that were officially introduced, respectively, in September 2012 and October 2017. The RX1 is a fixed lens compact, while the A7R III is a mirrorless interchangeable lens camera. Both cameras are equipped with a full frame sensor. The RX1 has a resolution of 24 megapixels, whereas the A7R III provides 42.2 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Cyber-shot DSC-RX1 and the Sony Alpha A7R III? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
Body comparison
The side-by-side display below illustrates the physical size and weight of the Sony RX1 and the Sony A7R III. 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.
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 larger (66 percent) than the Sony RX1. It is noteworthy in this context that the A7R III is splash and dust-proof, while the RX1 does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX1 has a lens built in, whereas the A7R III 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 A7R III and their specifications in the Sony FE Lens Catalog.
Concerning battery life, the RX1 gets 270 shots out of its NP-BX1 battery, while the A7R III can take 650 images on a single charge of its NP-FZ100 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.

Any camera decision 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 RX1 was launched at a lower price than the A7R III, despite having a lens built in. 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.
Sensor comparison
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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies and lenses.
Both cameras under consideration feature a full frame sensor, but their sensors differ slightly in size. The sensor area in the A7R III is 1 percent bigger. 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.
With 42.2MP, the A7R III offers a higher resolution than the RX1 (24MP), but the A7R III has smaller individual pixels (pixel pitch of 4.52μm versus 5.96μm for the RX1). Yet, the A7R III is a much more recent model (by 5 years and 1 month) than the RX1, 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.
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 RX1 are 30 x 20 inches or 76.2 x 50.8 cm for good quality, 24 x 16 inches or 61 x 40.6 cm for very good quality, and 20 x 13.3 inches or 50.8 x 33.9 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 RX1, 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 Cyber-shot DSC-RX1 has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 50-102400. 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.
In terms of underlying technology, the RX1 is build around a CMOS sensor, while the A7R III uses a BSI-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.
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 has a markedly higher DXO score than the RX1 (overall score 7 points higher), which will translate into better image quality. The advantage is based on 0.9 bits higher color depth, 0.4 EV in additional dynamic range, and 0.5 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 also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the A7R III provides a better video resolution than the RX1. It can shoot movie footage at 4K/30p, while the RX1 is limited to 1080/60p.
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), which can be very helpful when shooting in bright sunlight. In contrast, the RX1 relies on live view and the rear LCD for framing. That said, the RX1 can be equipped with an optional viewfinder – the FDA-EV1MK. The following table reports on some other key feature differences and similarities of the Sony RX1, the Sony A7R III, and comparable cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one. |
One difference between the cameras concerns the presence of an on-board flash. The RX1 has one, while the A7R III does not. While the built-in flash of the RX1 is not very powerful, it can at times be useful as a fill-in light.
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 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 RX1 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 RX1 only has one slot. The A7R III supports UHS-II cards on its first slot and UHS-I on its second one, while the RX1 cannot take advantage of Ultra High Speed SD cards.
Connectivity comparison
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Sony Cyber-shot DSC-RX1 and Sony Alpha A7R III and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7R III offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the RX1 does not provide wifi capability.
Studio photographers will appreciate that the Sony A7R III (unlike the RX1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the RX1 and the A7R III have been discontinued, but can regularly be found used on ebay. The RX1 was replaced by the Sony RX1R, while the A7R III was followed by the Sony A7R IV. Further information on the features and operation of the RX1 and A7R III can be found, respectively, in the Sony RX1 Manual (free pdf) or the online Sony A7R III Manual.
Review summary
So how do things add up? Is the Sony RX1 better than the Sony A7R III or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Sony Cyber-shot DSC-RX1:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Ready to shoot: Has a lens built-in, whereas the A7R III requires a separate lens.
- More compact: Is smaller (113x65mm vs 127x96mm) and thus needs less room in the bag.
- Less heavy: Is lighter even though it comes with a built-in lens (unlike the A7R III).
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More heavily discounted: Has been available for much longer (launched in September 2012).
Reasons to prefer the Sony Alpha A7R III:
- More detail: Has more megapixels (42.2 vs 24MP), which boosts linear resolution by 33%.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- High quality composites: Can combine several shots after pixel-shifting its sensor.
- Better image quality: Scores markedly higher (7 points) in the DXO overall evaluation.
- Better low-light sensitivity: Can shoot in dim conditions (0.5 stops ISO advantage).
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- Better sound control: Has a headphone port that enables audio monitoring while recording.
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- More detailed LCD: Has a higher resolution rear screen (1440k vs 1229k dots).
- 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 shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.

- Faster buffer clearing: Supports Ultra High Speed (UHS-II and UHS-I) SDXC cards.
- More modern: Reflects 5 years and 1 month of technical progress since the RX1 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 (28 : 7 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 RX1 and the Sony A7R III place the cameras among the top in their class? Find out in the latest Best Prime Lens Compact Camera and Best Mirrorless Interchangeable Lens 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 RX1 or the A7R III. 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 hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
