Canon T6i vs Nikon D4
The Canon EOS Rebel T6i (called Canon 750D in some regions) and the Nikon D4 are two digital cameras that were officially introduced, respectively, in February 2015 and January 2012. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (T6i) and a full frame (D4) sensor. The Canon has a resolution of 24 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 T6i and the Nikon D4? 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.
The physical size and weight of the Canon T6i and the Nikon D4 are illustrated 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 D4 is considerably larger (88 percent) than the Canon T6i. Moreover, the D4 is substantially heavier (141 percent) than the T6i. It is noteworthy in this context that the D4 is splash and dust-proof, while the T6i 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 (T6i) and the Nikon Lens Catalog (D4).
Concerning battery life, the T6i gets 440 shots out of its LP-E17 battery, while the D4 can take 2600 images on a single charge of its EN-EL18 power pack. As can be seen in the images above, the D4 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 T6i, Canon provides the BG-E18 vertical grip as an optional accessory (see here on eBay).

Any camera decision will naturally be influenced heavily by the price. 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 T6i was launched at a markedly lower price (by 88 percent) than the D4, 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. 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. 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 T6i features an APS-C sensor and the Nikon D4 a full frame sensor. The sensor area in the D4 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 T6i offers a higher resolution of 24 megapixels, compared with 16.2 MP of the Nikon D4. 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 7.29μm for the D4). However, it should be noted that the T6i is much more recent (by 3 years and 1 month) than the D4, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The resolution advantage of the Canon T6i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T6i 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 D4 are 24.6 x 16.4 inches or 62.6 x 41.7 cm for good quality, 19.7 x 13.1 inches or 50.1 x 33.3 cm for very good quality, and 16.4 x 10.9 inches or 41.7 x 27.8 cm for excellent quality prints.
The T6i has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS Rebel T6i has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. The corresponding ISO settings for the Nikon D4 are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 50-204800.
For many cameras, data on sensor performance has been reported by DXO Mark. 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 D4 offers substantially better image quality than the T6i (overall score 18 points higher). The advantage is based on 2 bits higher color depth, 1.1 EV in additional dynamic range, and 1.7 stops in additional low light sensitivity. 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 are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/30p).
Beyond body and sensor, cameras can and do differ across a range of features. The T6i and the D4 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 D4 offers a wider field of view (100%) than the one in the T6i (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the D4 has a higher magnification (0.70x vs 0.51x), 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 Canon T6i and Nikon D4 along with similar information for a selection of comparators.
One difference between the cameras concerns the presence of an on-board flash. The T6i has one, while the D4 does not. While the built-in flash of the T6i is not very powerful, it can at times be useful as a fill-in light.The T6i has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the D4 does not have a selfie-screen.
The Nikon D4 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 T6i writes its imaging data to SDXC cards, while the D4 uses Compact Flash or XQD cards. The D4 features dual card slots, which can be very useful in case a memory card fails. In contrast, the T6i 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 T6i and Nikon D4 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

| NFC |
It is notable that the T6i offers wifi support, while the D4 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Studio photographers will appreciate that the Nikon D4 (unlike the T6i) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the T6i and the D4 have been discontinued, but can regularly be found used on eBay. The D4 was replaced by the Nikon D4S, while the T6i was followed by the Canon T7i. 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 how do things add up? Which of the two cameras – the Canon T6i or the Nikon D4 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

If the number of relative strengths (bullet points above) is taken as a guide, the D4 is the clear winner of the contest (18 : 13 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

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 T6i or the D4 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 where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
