Body comparison

An illustration of the physical size and weight of the Sony A7 and the Nikon D850 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter.

Size Sony A7 vs Nikon D850
Compare A7 versus D850 top
Comparison A7 or D850 rear

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 (52 percent) than the Sony A7. Moreover, the D850 is substantially heavier (112 percent) than the A7. 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 (A7) and the Nikon Lens Catalog (D850). Mirrorless cameras, such as the Sony A7, 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 A7 gets 340 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 A7 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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 naturally be influenced heavily by the price. 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 A7 was launched at a markedly lower price (by 48 percent) than the D850, 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

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. 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, 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.

Sony A7 and Nikon D850 sensor measures

With 45.4MP, the D850 offers a higher resolution than the A7 (24MP), but the D850 has smaller individual pixels (pixel pitch of 4.35μm versus 5.97μm for the A7). Yet, the D850 is a much more recent model (by 3 years and 9 months) than the A7, and its sensor will 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 A7 are 30 x 20 inches or 76.2 x 50.8 cm for good quality, 24 x 16 inches or 61 x 40.6 cm for very good quality, and 20 x 13.3 inches or 50.8 x 33.9 cm for excellent quality prints.

The A7 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Sony Alpha A7 has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 50-51200. 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 A7 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.

A7 versus D850 MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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 D850 has a markedly higher DXO score than the A7 (overall score 10 points higher), which will translate into better image quality. The advantage is based on 1.6 bits higher color depth, 0.6 EV in additional dynamic range, and 0.2 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 can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the D850 provides a better video resolution than the A7. It can shoot movie footage at 4K/30p, while the Sony is limited to 1080/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the A7 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 D850 has a higher magnification than the one of the A7 (0.75x vs 0.71x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Sony A7, the Nikon D850, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The D850 has a touchscreen, while the A7 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

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 A7 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 A7 only has one slot. The D850 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the A7 can use UHS-I cards (up to 104 MB/s).

Studio photographers will appreciate that the Nikon D850 (unlike the A7) 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 A7 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the A7 was succeeded by the Sony A7 II. Further information on the features and operation of the A7 and D850 can be found, respectively, in the Sony A7 Manual (free pdf) or the online Nikon D850 Manual.

Review summary

So what is the bottom line? Is the Sony A7 better than the Nikon D850 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Reasons to prefer the Sony Alpha A7:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More compact: Is smaller (127x94mm vs 146x124mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 531g or 53 percent) and hence easier to carry around.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
  • More affordable: Was introduced into a lower priced category (48 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in October 2013).

ilogo

Arguments in favor of the Nikon D850:

  • More detail: Has more megapixels (45.4 vs 24MP), which boosts linear resolution by 38%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Scores markedly higher (10 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.6 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (0.6 EV of extra DR).
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.75x vs 0.71x).
  • 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 1230k 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 340) 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: Reflects 3 years and 9 months of technical progress since the A7 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the D850 is the clear winner of the contest (21 : 9 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 before making a camera decision. 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.

A7 09:21 D850

How about other alternatives? Do the specifications of the Sony A7 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the A7 or the D850. 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 following table reports the overall ratings of the cameras as published by some of the major camera 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 ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
