Nikon Df vs Sony A7 II

The Nikon Df and the Sony Alpha A7 II are two enthusiast cameras that were announced, respectively, in November 2013 and November 2014. The Df is a DSLR, while the A7 II is a mirrorless interchangeable lens camera. Both cameras are equipped with a full frame sensor. The Nikon has a resolution of 16.2 megapixels, whereas the Sony provides 24 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 Nikon Df and the Sony Alpha A7 II? 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: Nikon Df vs Sony A7 II

The physical size and weight of the Nikon Df and the Sony A7 II are illustrated 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.

The Df can be obtained in two different colors (black, silver), while the A7 II is only available in black.

Size Nikon Df vs Sony A7 II
Compare Df versus A7 II top
Comparison Df or A7 II rear

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 (23 percent) than the Nikon Df. Moreover, the A7 II is markedly lighter (21 percent) than the Df. 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 Nikon Lens Catalog (Df) and the Sony FE Lens Catalog (A7 II). Mirrorless cameras, such as the A7 II, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.

Concerning battery life, the Df gets 1400 shots out of its EN-EL14 battery, while the A7 II can take 350 images on a single charge of its NP-FW50 power pack. The power pack in the A7 II can be charged via the USB port, which can be very convenient when travelling.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

Any camera decision 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 27 percent) than the Df, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Nikon Df vs Sony A7 II

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 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.

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

Nikon Df and Sony A7 II sensor measures

Despite having a slightly smaller sensor, the A7 II offers a higher resolution of 24 megapixels, compared with 16.2 MP of the Df. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 5.97μm versus 7.29μm for the Df). However, it should be noted that the A7 II is a somewhat more recent model (by 1 year) than the Df, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.

The resolution advantage of the Sony A7 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7 II for good quality output (200 dots per inch) amounts to 30 x 20 inch or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inch or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inch or 50.8 x 33.9 cm. The corresponding values for the Nikon Df are 24.6 x 16.4 inch or 62.6 x 41.7 cm for good quality, 19.7 x 13.1 inch or 50.1 x 33.3 cm for very good quality, and 16.4 x 10.9 inch or 41.7 x 27.8 cm for excellent quality prints.

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

The Nikon Df has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 50-204800. The corresponding ISO settings for the Sony Alpha A7 II are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-51200.

Df versus A7 II MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 imaging performance.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The A7 II indeed provides for movie recording, while the Df does not. The highest resolution format that the A7 II can use is 1080/60p.

 

Feature comparison: Nikon Df vs Sony A7 II

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A7 II has an electronic viewfinder (2400k dots), while the Df 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 A7 II has a higher magnification than the one of the Df (0.71x vs 0.70x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Nikon Df and Sony A7 II along with similar information for a selection of comparators.

One feature that is present on the Df, but is missing on the A7 II is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The Nikon Df 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 Df writes its imaging data to SDXC cards, while the A7 II uses SDXC or Memory Stick PRO Duo cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

 

Connectivity comparison: Nikon Df vs Sony A7 II

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.

It is notable that the A7 II offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the Df does not offer wifi capability.

Studio photographers will appreciate that the Nikon Df (unlike the A7 II) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The Df is a recent model that features in the current product line-up of Nikon. In contrast, the A7 II has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the A7 II was succeeded by the Sony A7 III. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon and Sony websites.


Review summary: Nikon Df vs Sony A7 II

So what conclusions can be drawn? Is the Nikon Df better than the Sony A7 II or vice versa? The listing below highlights the relative strengths of the two models.

  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • More heavily discounted: Has been on the market for longer (launched in November 2013).

ilogo

Arguments in favor of the Sony Alpha A7 II:

  • More detail: Has more megapixels (24 vs 16.2MP), which boosts linear resolution by 22%.
  • Broader imaging potential: Can capture not only stills but also 1080/60p video.
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.71x vs 0.70x).
  • 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 shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • More compact: Is smaller (127x96mm vs 144x110mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 161g or 21 percent) and is thus easier to take along.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More affordable: Was introduced into a lower priced category (27 percent cheaper at launch).
  • More modern: Was introduced somewhat (1 year) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the A7 II is the clear winner of the contest (16 : 8 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.

Df 08:16 A7 II

How about other alternatives? Do the specifications of the Nikon Df and the Sony A7 II place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens 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 incomplete and does no justice, for example, to the way the Df or the A7 II perform in practice. 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.

Expert reviews: Nikon Df vs Sony A7 II

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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
