Sony A7 II versus Sony A7R
The Sony Alpha A7 II and the Sony Alpha A7R are two enthusiast cameras that were officially introduced, respectively, in November 2014 and October 2013. Both the A7 II and the A7R are mirrorless interchangeable lens cameras that are equipped with a full frame sensor. The A7 II has a resolution of 24 megapixel, whereas the A7R provides 36.2 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 A7 II vs Sony A7R
The side-by-side display below illustrates the physical size and weight of the Sony A7 II and the Sony A7R. Three consecutive views from the front, the top, and the rear side 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 A7 II – represents the basis or 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 is somewhat smaller (2 percent) than the Sony A7 II. Moreover, the A7R is markedly lighter (22 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 find an overview of suitable optics 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 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 A7 II was launched at a somewhat lower price (by 13 percent) than the A7R, which makes it more attractive for photographers on a tight budget. 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 A7 II vs Sony A7R
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 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 36.2MP, the A7R offers a higher resolution than the A7 II (24MP), but the A7R has smaller individual pixels (pixel pitch of 4.88μm versus 5.97μm for the A7 II). It is noteworthy in this context that the A7 II is a somewhat more recent model (by 1 year and 1 month) than the A7R, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the A7R has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
Consistent information on actual sensor performance is available from DXO Mark for most cameras. 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 has a markedly higher DXO score than the A7 II (overall score 5 points higher), which will translate into better image quality. The advantage is based on 0.7 bits higher color depth, 0.5 EV in additional dynamic range, and 0.2 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (1080/60p).
Feature comparison: Sony A7 II vs Sony A7R
Apart from body and sensor, cameras can and do differ across a range of features. The A7 II and the A7R 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.

Both the A7 II and the A7R have been discontinued, but can regularly be found used on eBay. The A7R was replaced by the Sony A7R II, while the A7 II was followed by the Sony A7 III.
Review summary: Sony A7 II vs Sony A7R
So how do things add up? Which of the two cameras – the Sony A7 II or the Sony A7R – has the upper hand? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Sony Alpha A7 II:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Faster burst: Shoots at higher frequency (5 vs 4 flaps/sec) to capture the decisive moment.
- Sharper images: Has hand-shake reducing image stabilization build-in.
- More affordable: Was introduced into a lower priced segment (13 percent cheaper at launch).
- More modern: Is somewhat more recent (announced 1 year and 1 month after the A7R).
Advantages of the Sony Alpha A7R:
- More detail: Has more megapixels (36.2 vs 24MP), which boosts linear resolution by 23%.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Scores markedly higher (5 points) in the DXO overall evaluation.
- Less heavy: Has a lower weight (by 134g or 22 percent) and is thus easier to take along.
- More heavily discounted: Has been on the market for longer (launched in October 2013).
If the number of relative strengths (bullet points above) is taken as a guide, the match-up finishes in a tie (5 points each). 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.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the A7 II or the A7R. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable. This is why expert reviews are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

Care should be taken when interpreting the review scores above, 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
