Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D3S and the Nikon D750? 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 side-by-side display below illustrates the physical size and weight of the Nikon D3S and the Nikon D750. 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.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D750 is considerably smaller (37 percent) than the Nikon D3S. Moreover, the D750 is substantially lighter (40 percent) than the D3S. 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Nikon Lens Catalog.

Concerning battery life, the D3S gets 4200 shots out of its Nikon EN-EL4a battery, while the D750 can take 1230 images on a single charge of its Nikon EN-EL15 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. In order to provide similar functionality for the D750, Nikon provides the MB-D16 vertical grip as an optional accessory (see here on ebay).

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

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The D750 was launched at a markedly lower price (by 56 percent) than the D3S, 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.

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.

Both cameras under consideration feature a full frame sensor, but their sensors differ slightly in size. They nevertheless have the same format factor of 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Technology-wise, the D750 uses a more advanced image processing engine (EXPEED 4) than the D3S (EXPEED), with benefits for noise reduction, color accuracy, and processing speed.

With 24.2MP, the D750 offers a higher resolution than the D3S (12.1MP), but the D750 has smaller individual pixels (pixel pitch of 5.97μm versus 8.43μm for the D3S). Yet, the D750 is a much more recent model (by 4 years and 10 months) than the D3S, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Nikon D750 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D750 for good quality output (200 dots per inch) amounts to 30.1 x 20.1 inches or 76.4 x 51 cm, for very good quality (250 dpi) 24.1 x 16.1 inches or 61.1 x 40.8 cm, and for excellent quality (300 dpi) 20.1 x 13.4 inches or 50.9 x 34 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 Nikon D3S has a native sensitivity range from ISO 200 to ISO 12800, which can be extended to ISO 100-102400. The corresponding ISO settings for the Nikon D750 are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 50-51200.

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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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"). Of the two cameras under consideration, the D750 offers substantially better image quality than the D3S (overall score 11 points higher). The advantage is based on 1.3 bits higher color depth, 2.5 EV in additional dynamic range, and 0.1 stops of reduced 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. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the D750 provides a better video resolution than the D3S. It can shoot movie footage at 1080/60p, while the D3S is limited to 720/24p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The D3S and the D750 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 viewfinders of both cameras offer the same field of view (100%), as well as the same magnification (0.70x). The following table reports on some other key feature differences and similarities of the Nikon D3S, the Nikon D750, 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 D750 has one, while the D3S does not. While the built-in flash of the D750 is not very powerful, it can at times be useful as a fill-in light.

The Nikon D3S and the Nikon D750 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 D3S writes its imaging data to Compact Flash cards, while the D750 uses SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.

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 D3S and Nikon D750 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D750 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the D3S does not provide wifi capability.

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

Both the D3S and the D750 have been discontinued, but can regularly be found used on ebay. The D3S was replaced by the Nikon D4, while the D750 was followed by the Nikon D780. Further information on the features and operation of the D3S and D750 can be found, respectively, in the Nikon D3S Manual (free pdf) or the online Nikon D750 Manual.

Review summary

So how do things add up? Which of the two cameras – the Nikon D3S or the Nikon D750 – 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 D3S:

• 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: Can take more shots (4200 versus 1230) on a single battery charge.
• More heavily discounted: Has been available for much longer (launched in October 2009).

Arguments in favor of the Nikon D750:

• More detail: Has more megapixels (24.2 vs 12.1MP), which boosts linear resolution by 41%.
• Better image quality: Scores substantially higher (11 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (1.3 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (2.5 EV of extra DR).
• 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.
• Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1229k vs 921k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• More compact: Is smaller (141x113mm vs 160x157mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 490g or 40 percent) and is thus easier to take along.
• 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.
• More affordable: Was introduced into a lower priced category (56 percent cheaper at launch).
• More modern: Reflects 4 years and 10 months of technical progress since the D3S launch.

If the count of individual advantages (bullet points above) is taken as a guide, the D750 is the clear winner of the contest (17 : 5 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 D3S and the Nikon D750 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 technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the D3S and the D750 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 where reviews by experts come in. 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.

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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning.
