Sony RX1R versus Sony RX100 III
The Sony Cyber-shot DSC-RX1R and the Sony Cyber-shot DSC-RX100 III are two digital cameras that were officially introduced, respectively, in June 2013 and May 2014. Both the RX1R and the RX100 III are fixed lens compact cameras that are based on a full frame (RX1R) and an one-inch (RX100 III) sensor. The RX1R has a resolution of 24 megapixel, whereas the RX100 III provides 20 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 RX1R vs Sony RX100 III
An illustration of the physical size and weight of the Sony RX1R and the Sony RX100 III is provided in the side-by-side display below. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter. You can also use the toggle button 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 RX1R – represents 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 Sony RX100 III is notably smaller (19 percent) than the Sony RX1R. Moreover, the RX100 III is substantially lighter (40 percent) than the RX1R. In this context, it is worth noting that neither the RX1R nor the RX100 III are weather-sealed.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

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 RX100 III was launched at a markedly lower price (by 71 percent) than the RX1R, which puts it into a different market segment. 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 RX1R vs Sony RX100 III
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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Sony RX1R features a full frame sensor and the Sony RX100 III an one-inch sensor. The sensor area in the RX100 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.
With 24MP, the RX1R offers a higher resolution than the RX100 III (20MP), but the RX1R nevertheless has larger individual pixels (pixel pitch of 5.97μm versus 2.41μm for the RX100 III) due to its larger sensor. However, the RX100 III is a somewhat more recent model (by 10 months) than the RX1R, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the RX1R has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 RX1R provides substantially higher image quality than the RX100 III, with an overall score that is 24 points higher. This advantage is based on 2.6 bits higher color depth, 1.3 EV in additional dynamic range, and 2.4 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.

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, and both provide the same movie specifications (1080/60p).
Feature comparison: Sony RX1R vs Sony RX100 III
Beyond body and sensor, cameras can and do differ across a range of features. For example, the RX100 III has an electronic viewfinder (1440k dots), which can be very helpful when shooting in bright sunlight. In contrast, the RX1R relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Sony RX1R and Sony RX100 III along with similar information for a selection of comparators.

The RX100 III is equipped with a zoom lens, while the RX1R comes with a build-in prime. The RX100 III has a 24-70mm f/1.8-2.8 optic and the RX1R offers a 35mm f/2.0 (focal lengths in full frame equivalent terms). Hence, the RX100 III provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the RX1R. The RX100 III offers the faster maximum aperture.
Both the RX1R and the RX100 III have been discontinued, but can regularly be found used on eBay. The RX1R was replaced by the Sony RX1R II, while the RX100 III was followed by the Sony RX100 IV.

If the count of relative strengths (bullet points above) is taken as a measure, the RX100 III is the clear winner of the contest (12 : 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.
In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the RX1R or the RX100 III. 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. This is why expert reviews are important. 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).

Care should be taken when interpreting the review scores above, 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.
