Canon XSi vs Nikon D4S
The Canon EOS Rebel XSi (called Canon 450D in some regions) and the Nikon D4S are two digital cameras that were announced, respectively, in January 2008 and February 2014. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (XSi) and a full frame (D4S) sensor. The Canon has a resolution of 12.2 megapixels, whereas the Nikon provides 16.2 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 Canon EOS Rebel XSi and the Nikon D4S? 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 Canon XSi and the Nikon D4S 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 width, height and depth 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 D4S is considerably larger (99 percent) than the Canon XSi. Moreover, the D4S is substantially heavier (158 percent) than the XSi. It is noteworthy in this context that the D4S is splash and dust-proof, while the XSi 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 Canon EF Lens Catalog (XSi) and the Nikon Lens Catalog (D4S).
Concerning battery life, the XSi gets 500 shots out of its LP-E5 battery, while the D4S can take 3020 images on a single charge of its EN-EL18a 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 XSi, Canon provides the BG-E5 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.

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 XSi was launched at a markedly lower price (by 88 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.
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 Canon XSi features an APS-C sensor and the Nikon D4S a full frame sensor. The sensor area in the D4S is 161 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.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
With 16.2MP, the D4S offers a higher resolution than the XSi (12.2MP), but the D4S nevertheless has larger individual pixels (pixel pitch of 7.29μm versus 5.19μm for the XSi) due to its larger sensor. Moreover, the D4S is a much more recent model (by 6 years and 1 month) than the XSi, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.
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 Canon XSi are 21.4 x 14.2 inches or 54.3 x 36.2 cm for good quality, 17.1 x 11.4 inches or 43.4 x 28.9 cm for very good quality, and 14.2 x 9.5 inches or 36.2 x 24.1 cm for excellent quality prints.
The Canon EOS Rebel XSi has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Nikon D4S are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-409600.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under consideration, the D4S offers substantially better image quality than the XSi (overall score 28 points higher). The advantage is based on 2.5 bits higher color depth, 2.5 EV in additional dynamic range, and 2.2 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 can also record movies. The D4S indeed provides for movie recording, while the XSi does not. The highest resolution format that the D4S can use is 1080/60p.
Beyond body and sensor, cameras can and do differ across a range of features. The XSi and the D4S 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 XSi (95%), 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 0.54x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Canon XSi, the Nikon D4S, and comparable cameras.
One difference between the cameras concerns the presence of an on-board flash. The XSi has one, while the D4S does not. While the built-in flash of the XSi 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 XSi writes its imaging data to SDHC cards, while the D4S uses Compact Flash or XQD cards. The D4S features dual card slots, which can be very useful in case a memory card fails. In contrast, the XSi 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 Canon EOS Rebel XSi and Nikon D4S and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Nikon D4S (unlike the XSi) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the XSi and the D4S have been discontinued, but can regularly be found used on eBay. The XSi was replaced by the Canon T1i, 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 Canon and Nikon websites.
So what conclusions can be drawn? Which of the two cameras – the Canon XSi or the Nikon D4S – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

If the count of individual advantages (bullet points above) is taken as a guide, the D4S is the clear winner of the contest (20 : 5 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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.

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 XSi and the D4S 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.
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], 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.
