Nikon D3X vs Sony A6400

The Nikon D3X and the Sony Alpha A6400 are two digital cameras that were officially introduced, respectively, in December 2008 and January 2019. The D3X is a DSLR, while the A6400 is a mirrorless interchangeable lens camera. The cameras are based on a full frame (D3X) and an APS-C (A6400) sensor. The Nikon has a resolution of 24.4 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 D3X and the Sony Alpha A6400? 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

The physical size and weight of the Nikon D3X and the Sony A6400 are illustrated in the side-by-side display below. 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 Nikon D3X vs Sony A6400
Compare D3X versus A6400 top
Comparison D3X or A6400 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A6400 is considerably smaller (68 percent) than the Nikon D3X. Moreover, the A6400 is substantially lighter (68 percent) than the D3X. 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Nikon Lens Catalog (D3X) and the Sony E-Mount Lens Catalog (A6400). Mirrorless cameras, such as the A6400, 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 D3X gets 4400 shots out of its EN-EL4a battery, while the A6400 can take 410 images on a single charge of its NP-FW50 power pack. As can be seen in the images above, the D3X has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. The power pack in the A6400 can be charged via the USB port, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The A6400 was launched at a markedly lower price (by 89 percent) than the D3X, 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. 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 imaging sensor is a crucial determinant 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Nikon D3X features a full frame sensor and the Sony A6400 an APS-C sensor. The sensor area in the A6400 is 57 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Nikon D3X and Sony A6400 sensor measures

With 24.4MP, the D3X offers a slightly higher resolution than the A6400 (24MP), but the D3X nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 3.91μm for the A6400) due to its larger sensor. However, the A6400 is a much more recent model (by 10 years and 1 month) than the D3X, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The A6400 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Nikon D3X has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 50-6400. The corresponding ISO settings for the Sony Alpha A6400 are ISO 100 to ISO 32000, with the possibility to increase the ISO range to 100-102400.

D3X versus A6400 MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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 review, the D3X has a notably higher overall DXO score than the A6400 (overall score 5 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.7 bits higher color depth, 0.1 EV in additional dynamic range, and 0.5 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Note: DXO values in italics represent estimates based on sensor size and age.

Many modern cameras cannot only take still pictures, but also record videos. The A6400 indeed provides for movie recording, while the D3X does not. The highest resolution format that the A6400 can use is 4K/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A6400 has an electronic viewfinder (2359k dots), while the D3X 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%), as well as the same magnification (0.70x). The table below summarizes some of the other core capabilities of the Nikon D3X and Sony A6400 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the D3X, but is missing on the A6400 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 A6400 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the D3X does not have a selfie-screen.

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 A6400 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 D3X 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 D3X writes its imaging data to Compact Flash cards, while the A6400 uses SDXC or Memory Stick PRO Duo cards. The D3X features dual card slots, which can be very useful in case a memory card fails. In contrast, the A6400 only has one slot.

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. The table below provides an overview of the connectivity of the Nikon D3X and Sony Alpha A6400 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A6400 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the D3X does not provide wifi capability.

Studio photographers will appreciate that the Nikon D3X (unlike the A6400) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The A6400 is a recent model that features in the current product line-up of Sony. In contrast, the D3X has been discontinued (but can be found pre-owned on eBay). There has not been a direct replacement model for the D3X from Nikon. 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

So how do things add up? Is the Nikon D3X better than the Sony A6400 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Reasons to prefer the Nikon D3X:

  • Better image quality: Scores markedly higher (5 points) in the DXO overall assessment.
  • Better low-light sensitivity: Requires less light for good images (0.5 stops ISO advantage).
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
  • Longer lasting: Can take more shots (4400 versus 410) on a single battery charge.
  • 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.
  • More heavily discounted: Has been available for much longer (launched in December 2008).

ilogo

Advantages of the Sony Alpha A6400:

  • Broader imaging potential: Can capture not only stills but also 4K/30p 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.
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (11 vs 5 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More compact: Is smaller (120x67mm vs 160x157mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 857g or 68 percent) and is thus easier to take along.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • 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.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • More affordable: Was introduced into a lower priced category (89 percent cheaper at launch).
  • More modern: Reflects 10 years and 1 month of technical progress since the D3X launch.

If the number of relative strengths (bullet points above) is taken as a guide, the A6400 is the clear winner of the contest (18 : 11 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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.

D3X 11:18 A6400

How about other alternatives? Do the specifications of the Nikon D3X and the Sony A6400 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the D3X or the A6400 perform in practice. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

Care should be taken when interpreting the review scores above, 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 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.
