Nikon D5600 versus Sony A99 II

The Nikon D5600 and the Sony Alpha ALT-A99 II are two digital cameras that were announced, respectively, in November 2016 and September 2016. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (D5600) and a full frame (A99 II) sensor. The Nikon has a resolution of 24 megapixel, whereas the Sony provides 42.2 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: Nikon D5600 vs Sony A99 II

An illustration of the physical size and weight of the Nikon D5600 and the Sony A99 II 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 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 D5600 – 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 A99 II is notably larger (24 percent) than the Nikon D5600. Moreover, the A99 II is substantially heavier (83 percent) than the D5600. It is noteworthy in this context that the A99 II is splash and dust-proof, while the D5600 does not feature any corresponding weather-sealing.

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.

Concerning battery life, the D5600 gets 970 shots out of its EN-EL14a battery, while the A99 II can take 490 images on a single charge of its NP-FM500H power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The D5600 was launched at a markedly lower price (by 78 percent) than the A99 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Nikon D5600 vs Sony A99 II

The size of the imaging sensor is a crucial determinant 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Nikon D5600 features an APS-C sensor and the Sony A99 II a full frame sensor. The sensor area in the A99 II is 135 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Nikon D5600 and Sony A99 II sensor measures

With 42.2MP, the A99 II offers a higher resolution than the D5600 (24MP), but the A99 II nevertheless has larger individual pixels (pixel pitch of 4.52μm versus 3.91μm for the D5600) due to its larger sensor. It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation. 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.

D5600 versus A99 II MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 A99 II has a markedly higher DXO score than the D5600 (overall score 8 points higher), which will translate into better image quality. The advantage is based on 1.3 bits higher color depth, 0.6 EV of lower dynamic range, and 0.8 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 are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the A99 II provides a better video resolution than the D5600. It can shoot movie footage at 4K/30p, while the Nikon is limited to 1080/60p.

 

Feature comparison: Nikon D5600 vs Sony A99 II

Apart from body and sensor, cameras can and do differ across a range of features. For example, the A99 II has an electronic viewfinder (2400k dots), while the D5600 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The adjacent table lists some of the other core features of the Nikon D5600 and Sony A99 II along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The D5600 has one, while the A99 II does not. While the build-in flash of the D5600 is not very powerful, it can at times be useful as a fill-in light.

The D5600 writes its imaging data to SDXC cards, while the A99 II uses SDXC or Memory Stick PRO Duo cards. The A99 II features dual card slots, which can be very useful in case a memory card fails. In contrast, the D5600 only has one slot.

D5600 09:14 A99 II

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the D5600 and the A99 II in practical situations. 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 (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
