Nikon D4S vs D90
The Nikon D4S and the Nikon D90 are two digital cameras that were revealed to the public, respectively, in February 2014 and August 2008. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (D4S) and an APS-C (D90) sensor. The D4S has a resolution of 16.2 megapixels, whereas the D90 provides 12.2 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 D4S and the Nikon D90? 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.
An illustration of the physical size and weight of the Nikon D4S and the Nikon D90 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 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 Nikon D90 is considerably smaller (46 percent) than the Nikon D4S. Moreover, the D90 is substantially lighter (48 percent) than the D4S. It is worth mentioning in this context that the D4S is splash and dust resistant, while the D90 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 (as in the D4S) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (D90). You can compare the optics available in the Nikon Lens Catalog.
Concerning battery life, the D4S gets 3020 shots out of its EN-EL18a battery, while the D90 can take 850 images on a single charge of its EN-EL3e 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. In order to provide similar functionality for the D90, Nikon provides the MB-D80 vertical grip as an optional accessory (see here on eBay).
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

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 D90 was launched at a markedly lower price (by 80 percent) than the D4S, 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.
The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Nikon D4S features a full frame sensor and the Nikon D90 an APS-C sensor. The sensor area in the D90 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.
In terms of chip-set technology, the D4S uses a more advanced image processing engine (EXPEED 4) than the D90 (EXPEED), with benefits for noise reduction, color accuracy, and processing speed.
With 16.2MP, the D4S offers a higher resolution than the D90 (12.2MP), but the D4S nevertheless has larger individual pixels (pixel pitch of 7.29μm versus 5.53μm for the D90) due to its larger sensor. Moreover, the D4S is a much more recent model (by 5 years and 6 months) than the D90, 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 D4S implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D4S for good quality output (200 dots per inch) amounts to 24.6 x 16.4 inches or 62.6 x 41.7 cm, for very good quality (250 dpi) 19.7 x 13.1 inches or 50.1 x 33.3 cm, and for excellent quality (300 dpi) 16.4 x 10.9 inches or 41.7 x 27.8 cm. The corresponding values for the Nikon D90 are 21.4 x 14.2 inches or 54.5 x 36.2 cm for good quality, 17.2 x 11.4 inches or 43.6 x 28.9 cm for very good quality, and 14.3 x 9.5 inches or 36.3 x 24.1 cm for excellent quality prints.
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 Nikon D90 are ISO 200 to ISO 3200, with the possibility to increase the ISO range to 200-6400.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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. Of the two cameras under review, the D4S provides substantially higher image quality than the D90, with an overall score that is 16 points higher. This advantage is based on 1.7 bits higher color depth, 0.8 EV in additional dynamic range, and 1.7 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 also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the D4S provides a higher video resolution than the D90. It can shoot video footage at 1080/60p, while the D90 is limited to 720/24p.
Beyond body and sensor, cameras can and do differ across a range of features. The D4S and the D90 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinder in the D4S offers a wider field of view (100%) than the one in the D90 (96%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the D4S has a higher magnification (0.70x vs 0.63x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Nikon D4S and Nikon D90 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The D90 has one, while the D4S does not. While the built-in flash of the D90 is not very powerful, it can at times be useful as a fill-in light.
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 D90 uses SDHC cards. The D4S features dual card slots, which can be very useful in case a memory card fails. In contrast, the D90 only has one slot.
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 Nikon D90 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 D90. 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 D4S (unlike the D90) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the D4S and the D90 have been discontinued, but can regularly be found used on eBay. The D90 was replaced by the Nikon D7000, while the D4S was followed by the Nikon D5. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon website.
So what is the bottom line? Is the Nikon D4S better than the Nikon D90 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Nikon D4S:
- More detail: Offers more megapixels (16.2 vs 12.2MP) with a 15% higher linear resolution.
- Better image quality: Scores substantially higher (16 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (1.7 bits more color depth).
- More dynamic range: Captures a larger spectrum of light and dark details (0.8 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (1.7 stops ISO advantage).
- Better jpgs: Has a more modern image processing engine (EXPEED 4 vs EXPEED).
- Better video: Provides higher definition movie capture (1080/60p vs 720/24p).
- 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.
- More complete view: Has a viewfinder with a larger field of view (100% vs 96%).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.63x).
- 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 4.5 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.

- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- More modern: Reflects 5 years and 6 months of technical progress since the D90 launch.
Advantages of the Nikon D90:
- More compact: Is smaller (132x103mm vs 160x157mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 647g or 48 percent) and is thus easier to take along.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- More affordable: Was introduced into a lower priced category (80 percent cheaper at launch).
- More heavily discounted: Has been around for much longer (launched in August 2008).
If the count of individual advantages (bullet points above) is taken as a guide, the D4S is the clear winner of the match-up (21 : 5 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.
How about other alternatives? Do the specifications of the Nikon D4S and the Nikon D90 place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing 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 D4S or the D90 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is why hands-on reviews by experts 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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
