Sony A7 II vs A7R II
The Sony Alpha A7 II and the Sony Alpha A7R II are two enthusiast cameras that were officially introduced, respectively, in November 2014 and June 2015. Both the A7 II and the A7R II are mirrorless interchangeable lens cameras that are equipped with a full frame sensor. The A7 II has a resolution of 24 megapixels, whereas the A7R II 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 Alpha A7 II and the Sony Alpha A7R II? 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.
The side-by-side display below illustrates the physical size and weight of the Sony A7 II and the Sony A7R II. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter.
In this particular case, the Sony A7 II and the Sony A7R II have exactly the same width and height, and, thus, have identically-sized bodies. However, the A7R II is slightly heavier (4 percent) than the A7 II. 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 since they do not consider the interchangeable lenses that both of these cameras require. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Sony FE Lens Catalog. Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.
The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The A7 II was launched at a markedly lower price (by 38 percent) than the A7R 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.
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. 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 more expensive and lead to bigger and heavier cameras 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.
With 42.2MP, the A7R II offers a higher resolution than the A7 II (24MP), but the A7R II has smaller individual pixels (pixel pitch of 4.52μm versus 5.97μm for the A7 II). Yet, the A7R II is a somewhat more recent model (by 6 months) than the A7 II, and its sensor might 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 II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Sony A7R II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7R II 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 A7 II 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 Sony Alpha A7 II has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 50-51200. The corresponding ISO settings for the Sony Alpha A7R II are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-102400.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 consideration, the A7R II has a markedly higher DXO score than the A7 II (overall score 8 points higher), which will translate into better image quality. The advantage is based on 1.1 bits higher color depth, 0.3 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 can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the A7R II provides a better video resolution than the A7 II. It can shoot movie footage at 4K/30p, while the A7 II is limited to 1080/60p.
Apart from body and sensor, cameras can and do differ across a range of features. The A7 II and the A7R II are similar in the sense that both feature an electronic viewfinder, which is helpful when framing images in bright sunlight. Moreover, their viewfinders offer an identical resolution of 2400k dots. The table below summarizes some of the other core capabilities of the Sony A7 II and Sony A7R II in connection with corresponding information for a sample of similar cameras.

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 II 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).
Concerning the storage of imaging data, both the A7 II and the A7R II write their files to SDXC or Memory Stick PRO Duo cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
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 Alpha A7 II and Sony Alpha A7R II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the A7 II and the A7R II have been discontinued, but can regularly be found used on eBay. The A7 II was replaced by the Sony A7 III, while the A7R II was followed by the Sony Alpha A7R III. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Sony website.
So how do things add up? Is the Sony A7 II better than the Sony A7R II or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Sony Alpha A7 II:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Longer lasting: Can take more shots (350 versus 290) on a single battery charge.
- More affordable: Was introduced into a lower priced category (38 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in November 2014).
Advantages of the Sony Alpha A7R II:
- 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.
- Better image quality: Scores markedly higher (8 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.1 bits more color depth).
- 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).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.78x vs 0.71x).
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- More modern: Was introduced somewhat (6 months) more recently.
If the count of individual advantages (bullet points above) is taken as a guide, the A7R II is the clear winner of the contest (9 : 4 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. 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.
How about other alternatives? Do the specifications of the Sony A7 II and the Sony A7R II place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing 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 says little about, for example, the shooting experience and imaging performance of the A7 II and the A7R II in practical situations. 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 adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
