Sony A99 versus Sony A7 II
The Sony Alpha SLT-A99 and the Sony Alpha A7 II are two digital cameras that were revealed to the public, respectively, in September 2012 and November 2014. The A99 is a DSLR, while the A7 II is a mirrorless interchangeable lens camera. Both cameras are equipped with a full frame sensor. Both cameras offer a resolution of 24 megapixel.
The physical size and weight of the Sony A99 and the Sony A7 II are illustrated in the side-by-side display below. 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 A99 – 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 A7 II is notably smaller (25 percent) than the Sony A99. Moreover, the A7 II is markedly lighter (26 percent) than the A99. 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 A7 II was launched at a markedly lower price (by 29 percent) than the A99, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 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. 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 A7 II has a slightly larger sensor, both cameras offer the same resolution of 24 megapixel. This implies that the A7 II has a lower pixel density and marginally larger individual pixels (with a pixel pitch of 5.97μm versus 5.96μm for the A99), which gives it a potential advantage in terms of light gathering capacity. In addition, the A7 II is much more recent (by 2 years and 2 months) than the A99, and its sensor will have benefitted from technological advances during this time.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 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 are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/60p).
Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the A7 II offers a slightly higher resolution than the one in the A99 (2400k vs 2359k dots). The adjacent table lists some of the other core features of the Sony A99 and Sony A7 II along with similar information for a selection of comparators. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

The A7 II is a current model that online retailers, such as amazon, will have in stock. In contrast, the A99 has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the A99 was succeeded by the Sony A99 II.
So what conclusions can be drawn? Is there a clear favorite between the Sony A99 and the Sony A99? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Sony Alpha SLT-A99:
- Easier setting verification: Has an LCD display on top to control shooting parameters.
- More flexible LCD: Has full-flex screen for odd-angle shots in portrait or landscape orientation.
- Faster burst: Shoots at higher frequency (6 vs 5 flaps/sec) to capture the decisive moment.
- Longer lasting: Can take more shots (500 versus 350) on a single battery charge.
- More heavily discounted: Has been available for much longer (launched in September 2012).
Advantages of the Sony Alpha A7 II:
- Better low-light sensitivity: Can shoot in dim conditions (0.7 stops ISO advantage).
- More compact: Is smaller (127x96mm vs 147x111mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 213g or 26 percent) and is thus easier to take along.
- More legacy lens friendly: Can use many non-native lenses via adapters.
- More affordable: Was introduced into a lower priced category (29 percent cheaper at launch).
- More modern: Reflects 2 years and 2 months of technical progress since the A99 launch.
If the count of relative strengths (bullet points above) is taken as a measure, the A7 II comes out slightly ahead of the A99 (6 : 5 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features.
In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the A99 and the A7 II in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is why hands-on reviews by experts are important. The table below summarizes the assessments of some of the best known camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
