Sony A99 II versus Sony A7R II

The Sony Alpha ALT-A99 II and the Sony Alpha A7R II are two digital cameras that were revealed to the public, respectively, in September 2016 and June 2015. The A99 II is a DSLR, 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.

Body comparison

An illustration of the physical size and weight of the Sony A99 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 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 side – the A99 II – represents the basis for the calculations 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 notably smaller (18 percent) than the Sony A99 II. Moreover, the A7R II is markedly lighter (26 percent) than the A99 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. Hence, you might want to study the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

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. The two cameras under review were launched at the same price and fall into the same 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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. 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 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.

Sensor size

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 42.2 megapixel. This similarity in sensor specs implies that both the A99 II and the A7R II have the same pixel density, as well as the same pixel size. It should, however, be noted that the A99 II is a somewhat more recent model (by 1 year and 3 months) than the A7R II, and its sensor might have benefitted from technological advances during this time. 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.

Sensor resolution

Consistent information on actual sensor performance is available from DXO Mark for most 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"). Of the two cameras under consideration, the A7R II has a markedly higher DXO score than the A99 II (overall score 6 points higher), which will translate into better image quality. The advantage is based on 0.6 bits higher color depth, 0.5 EV in additional dynamic range, and 0.6 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (4K/30p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The A99 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 A99 II and Sony A7R II in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

The A99 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.

Summary

So what is the bottom line? Is there a clear favorite between the Sony A99 II and the Sony A99 II? The listing below highlights the relative strengths of the two models.


Advantages of the Sony Alpha ALT-A99 II:

  • Easier setting verification: Has an LCD display on top to control shooting parameters.
  • Faster burst: Shoots at higher frequency (12 vs 5 flaps/sec) to capture the decisive moment.
  • Longer lasting: Can take more shots (490 versus 290) on a single battery charge.
  • More modern: Is somewhat more recent (announced 1 year and 3 months after the A7R II).

Reasons to prefer the Sony Alpha A7R II:

  • Better image quality: Scores markedly higher (6 points) in the DXO overall evaluation.
  • Better low-light sensitivity: Can shoot in dim conditions (0.6 stops ISO advantage).
  • More compact: Is smaller (127x96mm vs 143x104mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 224g or 26 percent) and is thus easier to take along.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • More heavily discounted: Has been on the market for longer (launched in June 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 (6 : 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.

A99 II 04:06 A7R II

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the A99 II or the A7R II handle or perform in practice. 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. 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 assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
