Sony RX1R II versus Sony RX100 IV
The Sony Cyber-shot DSC-RX1R II and the Sony Cyber-shot DSC-RX100 IV are two digital cameras that were officially introduced, respectively, in October 2015 and June 2015. Both the RX1R II and the RX100 IV are fixed lens compact cameras that are based on a full frame (RX1R II) and an one-inch sensor. The RX1R II has a resolution of 42.2 megapixel, whereas the RX100 IV provides 20 MP.
An illustration of the physical size and weight of the Sony RX1R II and the Sony RX100 IV is provided in the side-by-side display below. Three successive views from the front, the top, and the rear are shown. All size 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 II – 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 IV is notably smaller (19 percent) than the Sony RX1R II. Moreover, the RX100 IV is substantially lighter (41 percent) than the RX1R II. In this context, it is worth noting that neither the RX1R II nor the RX100 IV are weather-sealed.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The RX100 IV was launched at a markedly lower price (by 70 percent) than the RX1R II, 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.
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. 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Sony RX1R II features a full frame sensor and the Sony RX100 IV an one-inch sensor. The sensor area in the RX100 IV 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 42.2MP, the RX1R II offers a higher resolution than the RX100 IV (20MP), but the RX1R II nevertheless has larger individual pixels (pixel pitch of 4.50μm versus 2.41μm for the RX100 IV) due to its larger sensor. Moreover, the RX1R II is a somewhat more recent model (by 4 months) than the RX100 IV, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the RX1R II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
For most 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 RX1R II provides substantially higher image quality than the RX100 IV, with an overall score that is 27 points higher. This advantage is based on 3 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the RX100 IV provides a better video resolution than the RX1R II. It can shoot movie footage at 4K/30p, while the RX1R II is limited to 1080/60p.
Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the RX1R II offers a slightly higher resolution than the one in the RX100 IV (2360k vs 2359k dots). The adjacent table lists some of the other core features of the Sony RX1R II and Sony RX100 IV along with similar information for a selection of comparators. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

The RX100 IV is equipped with a zoom lens, while the RX1R II comes with a build-in prime. The RX100 IV has a 24-70mm f/1.8-2.8 optic and the RX1R II offers a 35mm f/2.0 (focal lengths in full frame equivalent terms). Hence, the RX100 IV provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the RX1R II. The RX100 IV offers the faster maximum aperture.
The RX1R II is a current model that online retailers, such as amazon, will have in stock. In contrast, the RX100 IV has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the RX100 IV was succeeded by the Sony RX100 V.
So what conclusions can be drawn? Is the Sony RX1R II better than the Sony RX100 IV or vice versa? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Sony Cyber-shot DSC-RX1R II:

If the count of relative strengths (bullet points above) is taken as a measure, the RX100 IV 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.
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 handling experience and imaging performance when actually working with the RX1R II or the RX100 IV. 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. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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