Canon 1D X vs 750D
The Canon EOS-1D X and the Canon EOS 750D (labelled Canon T6i in some countries) are two digital cameras that were announced, respectively, in October 2011 and February 2015. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (1DX) and an APS-C (750D) sensor. The 1DX has a resolution of 17.9 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-1D X 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.
An illustration of the physical size and weight of the Canon 1D X and the Canon 750D is provided 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 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 Canon 750D is considerably smaller (50 percent) than the Canon 1D X. Moreover, the 750D is substantially lighter (64 percent) than the 1DX. It is worth mentioning in this context that the 1DX 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 1DX) 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.
Concerning battery life, the 1DX gets 1120 shots out of its LP-E4N battery, while the 750D can take 440 images on a single charge of its LP-E17 power pack. As can be seen in the images above, the 1DX 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 750D, Canon provides the BG-E18 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. 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.

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 750D was launched at a markedly lower price (by 89 percent) than the 1DX, 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.
The size of the imaging sensor is a crucial determinant 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon 1D X 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.
In terms of underlying technology, both cameras are build around CMOS sensors.
Despite having a smaller sensor, the 750D offers a higher resolution of 24 megapixels, compared with 17.9 MP of the 1DX. 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 6.95μm for the 1DX). However, it should be noted that the 750D is much more recent (by 3 years and 3 months) than the 1DX, 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 750D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 750D 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 Canon 1D X are 25.9 x 17.3 inches or 65.8 x 43.9 cm for good quality, 20.7 x 13.8 inches or 52.7 x 35.1 cm for very good quality, and 17.3 x 11.5 inches or 43.9 x 29.3 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-1D X has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 50-204800. 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 1DX provides substantially higher image quality than the 750D, with an overall score that is 11 points higher. This advantage is based on 1.1 bits higher color depth, 0.2 EV of lower dynamic range, and 1.6 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 cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (1080/30p).
Apart from body and sensor, cameras can and do differ across a range of features. The 1DX 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 1DX 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 1DX has a higher magnification (0.76x 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 1D X and Canon 750D in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 1DX, 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 1DX does not have a selfie-screen.
The 1DX writes its imaging data to Compact Flash cards, while the 750D uses SDXC cards. The 1DX features dual card slots, which can be very useful in case a memory card fails. In contrast, the 750D 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-1D X 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 1DX does not provide wifi capability.
Studio photographers will appreciate that the Canon 1D X (unlike the 750D) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 1DX and the 750D have been discontinued, but can regularly be found used on eBay. The 1DX was replaced by the Canon 1DX Mark II, while the 750D was followed 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 there a clear favorite between the Canon 1D X and the Canon 750D? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Canon EOS-1D X:
- Better image quality: Scores substantially higher (11 points) in the DXO overall assessment.

- More modern: Reflects 3 years and 3 months of technical progress since the 1DX launch.
If the count of individual advantages (bullet points above) is taken as a guide, the 1DX emerges as the winner of the contest (15 : 12 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 1D X 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 1DX or the 750D. 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. Thus, a score needs to be put into the context of the launch date and the launch price 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.
