Body comparison

The side-by-side display below illustrates the physical size and weight of the Sony A7 III and the Nikon D4. 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 size dimensions are rounded to the nearest millimeter.

Size Sony A7 III vs Nikon D4
Compare A7 III versus D4 top
Comparison A7 III or D4 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D4 is considerably larger (106 percent) than the Sony A7 III. Moreover, the D4 is substantially heavier (106 percent) than the A7 III. 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 III) and the Nikon Lens Catalog (D4). Mirrorless cameras, such as the Sony A7 III, 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 III gets 610 shots out of its Sony NP-FZ100 battery, while the D4 can take 2600 images on a single charge of its Nikon EN-EL18 power pack. As can be seen in the images above, the D4 has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. In order to provide similar functionality for the A7 III, Sony provides the VG-C3EM vertical grip as an optional accessory (see here on ebay). The power pack in the A7 III can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The A7 III was launched at a markedly lower price (by 67 percent) than the D4, 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

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 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. 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.

Both cameras under consideration feature a full frame sensor, but their sensors differ slightly in size. The sensor area in the D4 is 2 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.

Sony A7 III and Nikon D4 sensor measures

Despite having a slightly smaller sensor, the Sony A7 III offers a higher resolution of 24 megapixels, compared with 16.2 MP of the Nikon D4. 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 5.94μm versus 7.29μm for the D4). However, it should be noted that the A7 III is much more recent (by 6 years and 1 month) than the D4, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Sony A7 III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7 III for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Nikon D4 are 24.6 x 16.4 inches or 62.6 x 41.7 cm for good quality, 19.7 x 13.1 inches or 50.1 x 33.3 cm for very good quality, and 16.4 x 10.9 inches or 41.7 x 27.8 cm for excellent quality prints.

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

The Sony Alpha A7 III has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 50-204800. The corresponding ISO settings for the Nikon D4 are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 50-204800.

In terms of underlying technology, the A7 III is build around a BSI-CMOS sensor, while the D4 uses a 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 III versus D4 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 review, the A7 III has a notably higher overall DXO score than the D4 (overall score 7 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.3 bits higher color depth, 1.6 EV in additional dynamic range, and 0.3 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 A7 III provides a higher video resolution than the D4. It can shoot video footage at 4K/30p, while the Nikon is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A7 III has an electronic viewfinder (2359k dots), while the D4 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 III has a higher magnification than the one of the D4 (0.78x vs 0.70x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Sony A7 III and Nikon D4 in connection with corresponding information for a sample of similar cameras.

One feature that differentiates the A7 III and the D4 is in-body image stabilization (IBIS). The A7 III reduces the risk of handshake-induced blur with all attached lenses, while the D4 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 A7 III 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 Sony A7 III and the Nikon D4 both have 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 III writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the D4 uses Compact Flash or XQD cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.

It is notable that the A7 III offers wifi support, while the D4 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Studio photographers will appreciate that the Nikon D4 (unlike the A7 III) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The A7 III is a recent model that features in the current product line-up of Sony. In contrast, the D4 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the D4 was succeeded by the Nikon D4S. Further information on the features and operation of the A7 III and D4 can be found, respectively, in the Sony A7 III Manual (free pdf) or the online Nikon D4 Manual.

  • 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 portrait friendly: Features an integrated vertical grip for easier portrait shooting.
  • Longer lasting: Gets more shots (2600 versus 610) out of a single battery charge.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • More heavily discounted: Has been around for much longer (launched in January 2012).

If the number of relative strengths (bullet points above) is taken as a guide, the A7 III is the clear winner of the match-up (22 : 7 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.

A7 III 22:07 D4

How about other alternatives? Do the specifications of the Sony A7 III and the Nikon D4 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 A7 III and the D4 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 hands-on reviews by experts 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 above review scores should be interpreted 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
