Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS R100 and the Nikon D3S? 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 Canon R100 and the Nikon D3S 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 Nikon D3S is considerably larger (152 percent) than the Canon R100. Moreover, the D3S is substantially heavier (248 percent) than the R100. It is noteworthy in this context that the D3S is splash and dust-proof, while the R100 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.
Concerning battery life, the R100 gets 400 shots out of its Canon LP-E17 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 following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 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 R100 was launched at a markedly lower price (by 91 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. 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 imaging sensor is a crucial determinant 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon R100 features an APS-C sensor and the Nikon D3S a full frame sensor. The sensor area in the D3S is 159 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Despite having a smaller sensor, the Canon R100 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 3.72μm versus 8.43μm for the D3S). However, it should be noted that the R100 is much more recent (by 13 years and 7 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. Coming back to sensor resolution, it should be mentioned that the R100 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Canon R100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the R100 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 R100 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS R100 has a native sensitivity range from ISO 100 to ISO 25600. 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.

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 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 R100 provides a higher video resolution than the D3S. It can shoot video footage at 4k/24p, while the Nikon is limited to 720/24p.
Feature comparison
Beyond body and sensor, cameras can and do differ across a range of features. For example, the R100 has an electronic viewfinder (2360k dots), while the D3S 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 viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the D3S has a higher magnification than the one of the R100 (0.70x vs 0.58x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon R100 and Nikon D3S in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The R100 has one, while the D3S does not. While the built-in flash of the R100 is not very powerful, it can at times be useful as a fill-in light.
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 R100 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 Canon R100 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 R100 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 R100 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 Canon EOS R100 and Nikon D3S and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the R100 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 R100) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The R100 is a recent model that features in the current product line-up of Canon. In contrast, the D3S has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the D3S was succeeded by the Nikon D4. Further information on the features and operation of the R100 and D3S can be found, respectively, in the Canon R100 Manual (free pdf) or the online Nikon D3S Manual.
Review summary
So how do things add up? Is the Canon R100 better than the Nikon D3S or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Canon EOS R100:
- More detail: Offers more megapixels (24 vs 12.1MP) with a 41% higher linear resolution.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better video: Provides higher definition movie capture (4k/24p vs 720/24p).

- Less disturbing: Has an electronic shutter option for completely silent shooting.
- More compact: Is smaller (116x86mm vs 160x157mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 884g or 71 percent) and hence easier to carry around.
- More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Easier wireless transfer: Supports Bluetooth for image sharing without cables.
- More affordable: Was introduced into a lower priced category (91 percent cheaper at launch).
- More modern: Reflects 13 years and 7 months of technical progress since the D3S launch.

Reasons to prefer the Nikon D3S:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.58x).
- 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 6.5 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 400) 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.

If the count of relative strengths (bullet points above) is taken as a measure, the R100 is the clear winner of the match-up (16 : 12 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 Canon R100 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the R100 or the D3S. 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 hands-on reviews by experts 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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
