Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D4S and the Fujifilm X-Pro1? 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 D4S and the Fujifilm X-Pro1 is provided 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 size dimensions are rounded to the nearest millimeter.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Fujifilm X-Pro1 is considerably smaller (54 percent) than the Nikon D4S. Moreover, the X-Pro1 is substantially lighter (67 percent) than the D4S. It is worth mentioning in this context that the D4S is splash and dust resistant, while the X-Pro1 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 (D4S) and the Fujinon X Lens Catalog (X-Pro1). Mirrorless cameras, such as the X-Pro1, 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 D4S gets 3020 shots out of its Nikon EN-EL18a battery, while the X-Pro1 can take 300 images on a single charge of its Fujifilm NP-W126 power pack. As can be seen in the images above, the D4S 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. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

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 X-Pro1 was launched at a markedly lower price (by 74 percent) than the D4S, 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 sensor inside a digital camera is one of the key determinants 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. 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.

Of the two cameras under consideration, the Nikon D4S features a full frame sensor and the Fujifilm X-Pro1 an APS-C sensor. The sensor area in the X-Pro1 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.

With 16.2MP, the D4S offers a slightly higher resolution than the X-Pro1 (16MP), but the D4S nevertheless has larger individual pixels (pixel pitch of 7.29μm versus 4.80μm for the X-Pro1) due to its larger sensor. Moreover, the D4S is a much more recent model (by 2 years and 1 month) than the X-Pro1, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the X-Pro1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The Nikon D4S has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 50-409600. The corresponding ISO settings for the Fujifilm X-Pro1 are ISO 200 to ISO 6400, with the possibility to increase the ISO range to 100-25600.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Like most digital cameras, the D4S uses a Bayer filter for capturing RGB colors on a square grid of photosensors. In contrast, the X-Pro1 employs a more randomized X-Trans layout of photosites, which according to Fujifilm helps to minimize moiré.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the D4S provides a higher frame rate than the X-Pro1. It can shoot video footage at 1080/60p, while the Fujifilm is limited to 1080/24p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the X-Pro1 has an electronic viewfinder (1440k dots), while the D4S 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 table below summarizes some of the other core capabilities of the Nikon D4S and Fujifilm X-Pro1 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the D4S, but is missing on the X-Pro1 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 D4S 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 D4S writes its imaging data to Compact Flash or XQD cards, while the X-Pro1 uses SDXC cards. The D4S features dual card slots, which can be very useful in case a memory card fails. In contrast, the X-Pro1 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 D4S and Fujifilm X-Pro1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D4S has a microphone port, which is missing on the X-Pro1. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.

Both the D4S and the X-Pro1 have been discontinued, but can regularly be found used on ebay. The X-Pro1 was replaced by the Fujifilm X-Pro2, while the D4S was followed by the Nikon D5. Further information on the features and operation of the D4S and X-Pro1 can be found, respectively, in the Nikon D4S Manual (free pdf) or the online Fujifilm X-Pro1 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Nikon D4S or the Fujifilm X-Pro1 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Nikon D4S:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better image quality: Features a larger and more technologically advanced imaging sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
• Better video: Provides higher movie framerates (1080/60p versus 1080/24p).
• Better sound: Can connect to an external microphone for higher quality sound recording.
• Better sound control: Has a headphone port that enables audio monitoring while recording.
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
• 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.
• 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 (3020 versus 300) on a single battery charge.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More modern: Reflects 2 years and 1 month of technical progress since the X-Pro1 launch.

Advantages of the Fujifilm X-Pro1:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• More framing info: Has an electronic viewfinder that displays shooting data.
• More detailed LCD: Has a higher resolution rear screen (1230k vs 921k dots).
• More compact: Is smaller (140x82mm vs 160x157mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 900g or 67 percent) and is thus easier to take along.
• More legacy lens friendly: Can use many non-native lenses via adapters.
• More affordable: Was introduced into a lower priced category (74 percent cheaper at launch).
• More heavily discounted: Has been around for much longer (launched in January 2012).

If the count of individual advantages (bullet points above) is taken as a guide, the D4S is the clear winner of the match-up (19 : 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 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.

How about other alternatives? Do the specifications of the Nikon D4S and the Fujifilm X-Pro1 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 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 D4S or the X-Pro1 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

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.

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.
