Canon 5DS vs 750D
The Canon EOS 5DS and the Canon EOS 750D (labelled Canon T6i in some countries) are two digital cameras that were revealed to the public in February 2015. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (5DS) and an APS-C (750D) sensor. The 5DS has a resolution of 50.3 megapixels, whereas the 750D provides 24 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 5DS and the Canon EOS 750D? 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 5DS and the Canon 750D are illustrated 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 Canon 750D is notably smaller (24 percent) than the Canon 5DS. Moreover, the 750D is substantially lighter (40 percent) than the 5DS. It is worth mentioning in this context that the 5DS is splash and dust resistant, while the 750D 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 5DS) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (750D). You can compare the optics available in the Canon EF Lens Catalog.
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.

Any camera decision will obviously take relative prices into account. 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 750D was launched at a markedly lower price (by 80 percent) than the 5DS, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 5DS features a full frame sensor and the Canon 750D an APS-C sensor. The sensor area in the 750D is 62 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 50.3MP, the 5DS offers a higher resolution than the 750D (24MP), but the 5DS nevertheless has larger individual pixels (pixel pitch of 4.14μm versus 3.72μm for the 750D) due to its larger sensor. It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation.
The resolution advantage of the Canon 5DS implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 5DS for good quality output (200 dots per inch) amounts to 43.4 x 29 inches or 110.3 x 73.6 cm, for very good quality (250 dpi) 34.8 x 23.2 inches or 88.3 x 58.8 cm, and for excellent quality (300 dpi) 29 x 19.3 inches or 73.6 x 49 cm. The corresponding values for the Canon 750D are 30 x 20 inches or 76.2 x 50.8 cm for good quality, 24 x 16 inches or 61 x 40.6 cm for very good quality, and 20 x 13.3 inches or 50.8 x 33.9 cm for excellent quality prints.
The 750D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS 5DS has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 50-12800. The corresponding ISO settings for the Canon EOS 750D are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 100-25600.
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 review, the 5DS provides substantially higher image quality than the 750D, with an overall score that is 16 points higher. This advantage is based on 2 bits higher color depth, 0.4 EV in additional dynamic range, and 1.4 stops in additional 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, and both provide the same movie specifications (1080/30p).
Beyond body and sensor, cameras can and do differ across a range of features. The 5DS and the 750D 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 5DS offers a wider field of view (100%) than the one in the 750D (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the 5DS has a higher magnification (0.71x vs 0.51x), 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 5DS and Canon 750D in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 5DS, but is missing on the 750D is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.The 750D has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the 5DS does not have a selfie-screen.
The Canon 5DS 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 5DS writes its imaging data to Compact Flash or SDXC cards, while the 750D uses SDXC cards. The 5DS features dual card slots, which can be very useful in case a memory card fails. In contrast, the 750D only has one slot. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
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 5DS and Canon EOS 750D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 750D offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 5DS does not provide wifi capability.
Studio photographers will appreciate that the Canon 5DS (unlike the 750D) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The 5DS is a recent model that features in the current product line-up of Canon. In contrast, the 750D has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the 750D was succeeded by the Canon 800D. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So how do things add up? Is the Canon 5DS better than the Canon 750D or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Canon EOS 5DS:
- More detail: Offers more megapixels (50.3 vs 24MP) with a 45% higher linear resolution.

If the count of individual advantages (bullet points above) is taken as a guide, the 5DS is the clear winner of the match-up (15 : 10 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 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.
How about other alternatives? Do the specifications of the Canon 5DS and the Canon 750D 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 remains incomplete and does no justice, for example, to the way the 5DS or the 750D 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 expert reviews are important. 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.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
