Sony RX1R II versus Sony A7R II
The Sony Cyber-shot DSC-RX1R II and the Sony Alpha A7R II are two enthusiast cameras that were announced, respectively, in October 2015 and June 2015. The RX1R II is a fixed lens compact, while the A7R II is a mirrorless interchangeable lens camera. Both cameras are equipped with a full frame sensor. Both cameras offer a resolution of 42.2 megapixel.
An illustration of the physical size and weight of the Sony RX1R II and the Sony A7R II 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. If you prefer, you can also use the toggle button to switch to a comparison in percentage 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 A7R II is considerably larger (66 percent) than the Sony RX1R II. It is noteworthy in this context that the A7R II is splash and dust-proof, while the RX1R II does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX1R II has a lens build in, whereas the A7R II is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can find an overview of optics for the A7R II and their specifications in the Sony FE Lens Catalog.
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 comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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. 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. 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.
Both cameras under consideration feature a full frame sensor, but their sensors differ slightly in size. The sensor area in the A7R II 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.
Even though the A7R II has a slightly larger sensor, both cameras offer the same resolution of 42.2 megapixel. This implies that the A7R II has a lower pixel density and marginally larger individual pixels (with a pixel pitch of 4.52μm versus 4.50μm for the RX1R II), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the RX1R II is a somewhat more recent model (by 4 months) than the A7R II, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size. 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.
For most cameras, data on sensor performance has been reported by DXO Mark. 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. The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. 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 can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the A7R II 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.
Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the A7R II offers a slightly higher resolution than the one in the RX1R II (2400k vs 2360k dots). The following table reports on some other key feature differences and similarities of the Sony RX1R II, the Sony A7R II, and comparable cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

The RX1R II is a current model that online retailers, such as amazon, will have in stock. In contrast, the A7R II has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the A7R II was succeeded by the Sony Alpha A7R III.
So what conclusions can be drawn? Is the Sony RX1R II better than the Sony A7R II 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:
- Ready to shoot: Has a lens build-in, whereas the A7R II 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 build-in lens (unlike the A7R II).
- More modern: Is somewhat more recent (announced 4 months after the A7R II).
Advantages of the Sony Alpha A7R II:
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
- Faster shutter: Has a higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
- More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
- Longer lasting: Gets more shots (290 versus 220) out of a single battery charge.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
- More heavily discounted: Has been on the market for longer (launched in October 2015).
If the count of individual advantages (bullet points above) is taken as a guide, the A7R II emerges as the winner of the match-up (7 : 4 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.
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 A7R II. 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 table below summarizes the assessments of some of the best known camera review sites.

The review scores listed above should be treated with care, though. The ratings are only valid when refering to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, 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.
