Sony A7 II versus Nikon D800E

The Sony Alpha A7 II and the Nikon D800E are two digital cameras that were announced, respectively, in November 2014 and February 2012. The A7 II is a mirrorless interchangeable lens camera, while the D800 is a DSLR. Both cameras are equipped with a full frame sensor. The Sony has a resolution of 24 megapixel, whereas the Nikon provides 36.2 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: Sony A7 II vs Nikon D800E

An illustration of the physical size and weight of the Sony A7 II and the Nikon D800E 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 size dimensions are rounded to the nearest millimeter. You can also toggle the display 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 A7 II – 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 Nikon D800E is considerably larger (47 percent) than the Sony A7 II. Moreover, the D800 is substantially heavier (67 percent) than the A7 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 find an overview of optics for the two cameras in the Sony FE Lens Catalog (A7 II) and the Nikon Lens Catalog (D800). Mirrorless cameras, such as the Sony A7 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 A7 II gets 350 shots out of its NP-FW50 battery, while the D800 can take 900 images on a single charge of its EN-EL15 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera purchase will naturally be influenced heavily by the price. The listed launch 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 39 percent) than the D800, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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: Sony A7 II vs Nikon D800E

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 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. The sensor area in the D800 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.

In terms of underlying technology, both cameras are build around CMOS sensors.

Sony A7 II and Nikon D800E sensor measures

With 36.2MP, the D800 offers a higher resolution than the A7 II (24MP), but the D800 has smaller individual pixels (pixel pitch of 4.88μm versus 5.97μm for the A7 II). Yet, the A7 II is a much more recent model (by 2 years and 9 months) than the D800, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the D800 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

A7 II versus D800 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 D800 has a markedly higher DXO score than the A7 II (overall score 6 points higher), which will translate into better image quality. The advantage is based on 0.7 bits higher color depth, 0.7 EV in additional dynamic range, and 0.3 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

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, but the A7 II provides a higher frame rate than the D800. It can shoot video footage at 1080/60p, while the Nikon is limited to 1080/30p.

 

Feature comparison: Sony A7 II vs Nikon D800E

Apart from body and sensor, cameras can and do differ across a range of features. For example, the A7 II has an electronic viewfinder (2400k dots), while the D800 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 table below summarizes some of the other core capabilities of the Sony A7 II and Nikon D800E in connection with corresponding information for a sample of similar cameras.

Review summary: Sony A7 II vs Nikon D800E

So how do things add up? Is the Sony A7 II better than the Nikon D800E or vice versa? The listing below highlights the relative strengths of the two models.

ilogo

Advantages of the Sony Alpha A7 II:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More detailed LCD: Has a higher resolution rear screen (1230k vs 921k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster burst: Shoots at higher frequency (5 vs 4 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (127x96mm vs 146x123mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 401g or 40 percent) and hence easier to carry around.
  • More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
  • Sharper images: Has hand-shake reducing image stabilization build-in.
  • More affordable: Was introduced into a lower priced category (39 percent cheaper at launch).
  • More modern: Reflects 2 years and 9 months of technical progress since the D800 launch.

ilogo

Reasons to prefer the Nikon D800E:

  • More detail: Has more megapixels (36.2 vs 24MP), which boosts linear resolution by 23%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Scores markedly higher (6 points) in the DXO overall evaluation.
  • More dynamic range: Captures a broader range of light and dark details (0.7 EV of extra DR).
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Easier setting verification: Has 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.
  • Longer lasting: Gets more shots (900 versus 350) out of a single battery charge.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More heavily discounted: Has been around for much longer (launched in February 2012).

If the count of individual advantages (bullet points above) is taken as a guide, the A7 II emerges as the winner of the contest (12 : 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.

A7 II 12:10 D800

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 A7 II and the D800 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 table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
