Nikon D3X vs Sony NEX-5T

The Nikon D3X and the Sony Alpha NEX-5T are two digital cameras that were revealed to the public, respectively, in December 2008 and August 2013. The D3X is a DSLR, while the NEX-5T is a mirrorless interchangeable lens camera. The cameras are based on a full frame (D3X) and an APS-C (NEX-5T) sensor. The Nikon has a resolution of 24.4 megapixels, whereas the Sony provides 16 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 NEX-5T? 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

An illustration of the physical size and weight of the Nikon D3X and the Sony NEX-5T is provided 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 width, height and depth measures are rounded to the nearest millimeter.

The NEX-5T can be obtained in two different colors (black, silver), while the D3X is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony NEX-5T is considerably smaller (74 percent) than the Nikon D3X. Moreover, the NEX-5T is substantially lighter (78 percent) than the D3X. It is worth mentioning in this context that the D3X is splash and dust resistant, while the NEX-5T does not feature any corresponding weather-sealing.

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 (NEX-5T). Mirrorless cameras, such as the NEX-5T, 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 Nikon EN-EL4a battery, while the NEX-5T can take 330 images on a single charge of its Sony 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 adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Any camera decision will obviously take relative prices into account. 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 NEX-5T was launched at a markedly lower price (by 91 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the 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 NEX-5T an APS-C sensor. The sensor area in the NEX-5T is 58 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.

With 24.4MP, the D3X offers a higher resolution than the NEX-5T (16MP), but the D3X nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 4.78μm for the NEX-5T) due to its larger sensor. However, the NEX-5T is a much more recent model (by 4 years and 8 months) 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 resolution advantage of the Nikon D3X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D3X for good quality output (200 dots per inch) amounts to 30.2 x 20.2 inches or 76.8 x 51.2 cm, for very good quality (250 dpi) 24.2 x 16.1 inches or 61.4 x 41 cm, and for excellent quality (300 dpi) 20.2 x 13.4 inches or 51.2 x 34.1 cm. The corresponding values for the Sony NEX-5T are 24.6 x 16.3 inches or 62.4 x 41.5 cm for good quality, 19.6 x 13.1 inches or 49.9 x 33.2 cm for very good quality, and 16.4 x 10.9 inches or 41.6 x 27.6 cm for excellent quality prints.

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 NEX-5T are ISO 100 to ISO 25600 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

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 review, the D3X has a notably higher overall DXO score than the NEX-5T (overall score 10 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1.1 bits higher color depth, 0.7 EV in additional dynamic range, and 1 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 cannot only take still pictures, but also record videos. The NEX-5T indeed provides for movie recording, while the D3X does not. The highest resolution format that the NEX-5T can use is 1080/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the D3X has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the NEX-5T relies on live view and the rear LCD for framing. That said, the NEX-5T can be equipped with an optional viewfinder – the FDA-EV1S. The following table reports on some other key feature differences and similarities of the Nikon D3X, the Sony NEX-5T, and comparable cameras.

One feature that is present on the D3X, but is missing on the NEX-5T 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 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 NEX-5T 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 NEX-5T 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 NEX-5T and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the NEX-5T 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 NEX-5T) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the D3X and the NEX-5T have been discontinued, but can regularly be found used on ebay. The NEX-5T was replaced by the Sony A5100, while the D3X does not have a direct successor. Further information on the features and operation of the D3X and NEX-5T can be found, respectively, in the Nikon D3X Manual (free pdf) or the online Sony NEX-5T Manual.

Review summary

So what is the bottom line? Is the Nikon D3X better than the Sony NEX-5T or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Nikon D3X:

• More detail: Offers more megapixels (24.4 vs 16MP) with a 23% higher linear resolution.
• Better image quality: Scores markedly higher (10 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (1.1 bits more color depth).
• More dynamic range: Captures a larger spectrum of light and dark details (0.7 EV of extra DR).
• Better low-light sensitivity: Requires less light for good images (1 stops ISO advantage).
• Easier framing: Has an optical viewfinder for image composition and settings control.
• 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 330) on a single battery charge.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• 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).

Arguments in favor of the Sony Alpha NEX-5T:

• Broader imaging potential: Can capture not only stills but also 1080/60p video.
• 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 (10 vs 5 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (111x59mm vs 160x157mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 984g or 78 percent) and is thus easier to take along.
• 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 (91 percent cheaper at launch).
• More modern: Reflects 4 years and 8 months of technical progress since the D3X launch.

If the count of relative strengths (bullet points above) is taken as a measure, the D3X emerges as the winner of the contest (15 : 12 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.

How about other alternatives? Do the specifications of the Nikon D3X and the Sony NEX-5T 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 says little about, for example, the shooting experience and imaging performance of the D3X and the NEX-5T 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 expert reviews 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 ratings are only valid when referring to cameras in the same category and of the same age. 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.
