Sony A7R II versus Sony A7R

The Sony Alpha A7R II and the Sony Alpha A7R are two enthusiast cameras that were announced, respectively, in June 2015 and October 2013. Both the A7R II and the A7R are mirrorless interchangeable lens cameras that are equipped with a full frame sensor. The A7R II has a resolution of 42.2 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 A7R II vs Sony A7R

An illustration of the physical size and weight of the Sony A7R II and the Sony A7R is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures 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 A7R 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 is somewhat smaller (2 percent) than the Sony A7R II. Moreover, the A7R is markedly lighter (26 percent) than the A7R 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 adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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 camera’s price is obviously a critical decision-making factor. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The A7R was launched at a markedly lower price (by 28 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.

 

Sensor comparison: Sony A7R II vs Sony A7R

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature a full frame sensor and have a format factor (sometimes also referred to as "crop factor") of 1.0. Within the spectrum of camera sensors, this places the review cameras among the large-sensor cameras that aim for top notch image quality. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sony A7R II and Sony A7R sensor measures

While the two cameras under review share the same sensor size, the A7R II offers a higher resolution of 42.2 megapixel, compared with 36.2 MP of the A7R. This megapixel advantage translates into a 8 percent gain in linear resolution. On the other hand, these sensor specs imply that the A7R II has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.52μm versus 4.88μm for the A7R). In this context, it should be noted, however, that the A7R II is a somewhat more recent model (by 1 year and 7 months) than the A7R, 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.

A7R II versus A7R MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. 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 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 higher video resolution than the A7R. It can shoot video footage at 4K/30p, while the A7R is limited to 1080/60p.

 

Feature comparison: Sony A7R II vs Sony A7R

Beyond body and sensor, cameras can and do differ across a range of features. The A7R 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. The following table reports on some other key feature differences and similarities of the Sony A7R II, the Sony A7R, and comparable cameras.

One feature that differentiates the A7R II and the A7R is in-body image stabilization (IBIS). The A7R II reduces the risk of handshake-induced blur with all attached lenses, while the A7R has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

Both the A7R II and the A7R write their imaging data to SDXC or Memory Stick PRO Duo cards.

Both the A7R 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 A7R II was followed by the Sony Alpha A7R III.

Review summary: Sony A7R II vs Sony A7R

So how do things add up? Which of the two cameras – the Sony A7R II or the Sony A7R – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.


Arguments in favor of the Sony Alpha A7R II:

  • More detail: Offers more megapixels (42.2 vs 36.2MP) with a 8% higher linear resolution.
  • Better low-light sensitivity: Requires less light for good images (0.3 stops ISO advantage).
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • 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 modern: Is somewhat more recent (announced 1 year and 7 months after the A7R).


Advantages of the Sony Alpha A7R:

  • Less heavy: Has a lower weight (by 160g or 26 percent) and is thus easier to take along.
  • Longer lasting: Gets more shots (340 versus 290) out of a single battery charge.
  • More affordable: Was introduced into a lower priced category (28 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in October 2013).

If the count of individual advantages (bullet points above) is taken as a guide, the A7R II emerges as the winner of the contest (6 : 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 when reflecting and deciding on a new camera.

A7R II 06:04 A7R

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 A7R II or the A7R. 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 where reviews by experts come in. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
