Sony A7S II vs Nikon D850
The Sony Alpha 7S II and the Nikon D850 are two professional cameras that were announced, respectively, in September 2015 and July 2017. The A7S II is a mirrorless interchangeable lens camera, while the D850 is a DSLR. Both cameras are equipped with a full frame sensor. The Sony has a resolution of 12 megapixels, whereas the Nikon provides 45.4 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Alpha 7S II and the Nikon D850? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
Body comparison
An illustration of the physical size and weight of the Sony A7S II and the Nikon D850 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D850 is considerably larger (48 percent) than the Sony A7S II. Moreover, the D850 is substantially heavier (60 percent) than the A7S 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. Both cameras have similarly sized sensors, but DSLRs have a larger flange-to-focal plane distance than mirrorless cameras, which imposes contraints on the optical engineering process and generally leads to bigger and heavier lenses. You can compare the optics available for the two cameras in the Sony FE Lens Catalog (A7S II) and the Nikon Lens Catalog (D850). Mirrorless cameras, such as the Sony A7S II, have moreover the advantage that they have a relatively short flange to focal plane distance and can thus use many lenses from other systems via adapters.
Concerning battery life, the A7S II gets 370 shots out of its Sony NP-FW50 battery, while the D850 can take 1840 images on a single charge of its Nikon EN-EL15a power pack. The power pack in the A7S II can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will obviously take relative prices into account. 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 A7S II was somewhat cheaper (by 9 percent) than the D850 at launch, but both cameras fall into the same price category. 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 sensor inside a digital camera is one of the key determinants 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 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 D850 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 45.4MP, the D850 offers a higher resolution than the A7S II (12MP), but the D850 has smaller individual pixels (pixel pitch of 4.35μm versus 8.40μm for the A7S II). Yet, the D850 is a somewhat more recent model (by 1 year and 10 months) than the A7S II, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the D850 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Nikon D850 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D850 for good quality output (200 dots per inch) amounts to 41.3 x 27.5 inches or 104.9 x 69.9 cm, for very good quality (250 dpi) 33 x 22 inches or 83.9 x 55.9 cm, and for excellent quality (300 dpi) 27.5 x 18.3 inches or 69.9 x 46.6 cm. The corresponding values for the Sony A7S II are 21.2 x 14.2 inches or 53.8 x 36 cm for good quality, 17 x 11.3 inches or 43.1 x 28.8 cm for very good quality, and 14.1 x 9.4 inches or 35.9 x 24 cm for excellent quality prints.
The Sony Alpha 7S II has a native sensitivity range from ISO 100 to ISO 102400, which can be extended to ISO 50-409600. The corresponding ISO settings for the Nikon D850 are ISO 64 to ISO 25600, with the possibility to increase the ISO range to 32-102400.
In terms of underlying technology, the A7S II is build around a CMOS sensor, while the D850 uses a BSI-CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.
For many cameras, data on sensor performance has been reported by DXO Mark. 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 D850 offers substantially better image quality than the A7S II (overall score 15 points higher). The advantage is based on 2.8 bits higher color depth, 1.5 EV in additional dynamic range, and 0.2 stops of reduced 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 have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (4K/30p).
Feature comparison
Beyond body and sensor, cameras can and do differ across a range of features. For example, the A7S II has an electronic viewfinder (2400k dots), while the D850 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 viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the A7S II has a higher magnification than the one of the D850 (0.78x vs 0.75x), so that the size of the image transmitted appears closer to the size seen with the naked human eye.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one. |
One feature that differentiates the A7S II and the D850 is in-body image stabilization (IBIS). The A7S II reduces the risk of handshake-induced blur with all attached lenses, while the D850 offers no blur reduction with lenses that themselves do not provide optical image stabilization.
The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the A7S II is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The Nikon D850 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
The A7S II writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the D850 uses SDXC or XQD cards. The D850 features dual card slots, which can be very useful in case a memory card fails. In contrast, the A7S II only has one slot. The D850 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the A7S II can use UHS-I cards (up to 104 MB/s).
Connectivity comparison
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process.

Studio photographers will appreciate that the Nikon D850 (unlike the A7S II) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The D850 is a recent model that features in the current product line-up of Nikon. In contrast, the A7S II has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the A7S II was succeeded by the Sony A7S III. Further information on the features and operation of the A7S II and D850 can be found, respectively, in the Sony A7S II Manual (free pdf) or the online Nikon D850 Manual.
Review summary
So what conclusions can be drawn? Which of the two cameras – the Sony A7S II or the Nikon D850 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Sony Alpha 7S II:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- More framing info: Has an electronic viewfinder that displays shooting data.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.78x vs 0.75x).
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- More compact: Is smaller (127x96mm vs 146x124mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 378g or 38 percent) and hence easier to carry around.
- Easier travel charging: Can be conveniently charged via its USB port.
- Sharper images: Has hand-shake reducing image stabilization built-in.
- More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
- More heavily discounted: Has been on the market for longer (launched in September 2015).
Reasons to prefer the Nikon D850:
- More detail: Has more megapixels (45.4 vs 12MP), which boosts linear resolution by 95%.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Scores substantially higher (15 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (2.8 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (1.5 EV of extra DR).
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- Easier setting verification: Features a control panel on top to check shooting parameters.
- Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (2359k vs 1229k dots).
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- Faster burst: Shoots at higher frequency (9 vs 5 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Longer lasting: Gets more shots (1840 versus 370) out of a single battery charge.
- Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
- Easier wireless transfer: Supports Bluetooth for image sharing without cables.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
- More modern: Was introduced somewhat (1 year and 10 months) more recently.
If the number of relative strengths (bullet points above) is taken as a guide, the D850 is the clear winner of the contest (19 : 10 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. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Sony A7S II and the Nikon D850 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the A7S II and the D850 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.
Expert reviews
This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
