Fujifilm X-A7 vs Nikon D3S

The Fujifilm X-A7 and the Nikon D3S are two digital cameras that were officially introduced, respectively, in September 2019 and October 2009. The X-A7 is a mirrorless interchangeable lens camera, while the D3S is a DSLR. The cameras are based on an APS-C (X-A7) and a full frame (D3S) sensor. The Fujifilm has a resolution of 24 megapixels, whereas the Nikon provides 12.1 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Body comparison

The physical size and weight of the Fujifilm X-A7 and the Nikon D3S are illustrated 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 width, height and depth measures are rounded to the nearest millimeter.

The X-A7 can be obtained in four different colors (silver, graphite, brown, green), while the D3S is only available in black.

Size Fujifilm X-A7 vs Nikon D3S
Compare X-A7 versus D3S top
Comparison X-A7 or D3S rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D3S is considerably larger (210 percent) than the Fujifilm X-A7. Moreover, the D3S is substantially heavier (288 percent) than the X-A7. It is noteworthy in this context that the D3S is splash and dust-proof, while the X-A7 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 Fujinon X Lens Catalog (X-A7) and the Nikon Lens Catalog (D3S). Mirrorless cameras, such as the Fujifilm X-A7, 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 X-A7 gets 440 shots out of its Fujifilm NP-W126S battery, while the D3S can take 4200 images on a single charge of its Nikon EN-EL4a power pack. As can be seen in the images above, the D3S has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. The power pack in the X-A7 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

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

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

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 X-A7 was launched at a markedly lower price (by 90 percent) than the D3S, 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 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Fujifilm X-A7 features an APS-C sensor and the Nikon D3S a full frame sensor. The sensor area in the D3S is 133 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Fujifilm X-A7 and Nikon D3S sensor measures

Despite having a smaller sensor, the Fujifilm X-A7 offers a higher resolution of 24 megapixels, compared with 12.1 MP of the Nikon D3S. 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 3.92μm versus 8.43μm for the D3S). However, it should be noted that the X-A7 is much more recent (by 9 years and 11 months) than the D3S, 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 Fujifilm X-A7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X-A7 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 D3S are 21.3 x 14.2 inches or 54.1 x 36 cm for good quality, 17 x 11.3 inches or 43.2 x 28.8 cm for very good quality, and 14.2 x 9.4 inches or 36 x 24 cm for excellent quality prints.

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

The Fujifilm X-A7 has a native sensitivity range from ISO 200 to ISO 12800, which can be extended to ISO 200-51200. The corresponding ISO settings for the Nikon D3S are ISO 200 to ISO 12800, with the possibility to increase the ISO range to 100-102400.

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.

X-A7 versus D3S 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").

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the X-A7 provides a higher video resolution than the D3S. It can shoot video footage at 4K/30p, while the Nikon is limited to 720/24p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the D3S has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the X-A7 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Fujifilm X-A7, the Nikon D3S, and comparable cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One difference between the cameras concerns the presence of an on-board flash. The X-A7 has one, while the D3S does not. While the built-in flash of the X-A7 is not very powerful, it can at times be useful as a fill-in light.

The X-A7 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the D3S 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 X-A7 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 Fujifilm X-A7 and the Nikon D3S 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 X-A7 writes its imaging data to SDXC cards, while the D3S uses Compact Flash cards. The D3S features dual card slots, which can be very useful in case a memory card fails. In contrast, the X-A7 only has one slot.

It is notable that the X-A7 has a microphone port, which is missing on the D3S. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Studio photographers will appreciate that the Nikon D3S (unlike the X-A7) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the X-A7 and the D3S have been discontinued, but can regularly be found used on ebay. The D3S was replaced by the Nikon D4, while the X-A7 does not have a direct successor. Further information on the features and operation of the X-A7 and D3S can be found, respectively, in the Fujifilm X-A7 Manual (free pdf) or the online Nikon D3S Manual.

ilogo

Reasons to prefer the Nikon D3S:

  • Easier framing: Has an optical viewfinder for image composition and settings control.
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (11 vs 6 flaps/sec) to capture the decisive moment.
  • More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
  • Longer lasting: Gets more shots (4200 versus 440) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • 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 around for much longer (launched in October 2009).

If the number of relative strengths (bullet points above) is taken as a guide, the X-A7 is the clear winner of the match-up (19 : 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. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

X-A7 19:10 D3S

How about other alternatives? Do the specifications of the Fujifilm X-A7 and the Nikon D3S 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the X-A7 or the D3S 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 adjacent summary-table relays the overall verdicts of several of the most popular 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.

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

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
