Canon 1D X versus Canon 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 megapixel, whereas the 750D provides 24 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon 1D X vs Canon 750D

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 you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the 1DX – represents 100 percent across all the size and weight measures).

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 find a comprehensive overview of suitable optics 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 build in. This facilitates image-taking in portrait orientation and contributes to its long-lasting power supply. 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.

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.

 

Sensor comparison: Canon 1D X vs Canon 750D

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.

Canon 1D X and Canon 750D sensor measures

Despite having a smaller sensor, the 750D offers a higher resolution of 24 megapixel, compared with 17.9 MP of the 1DX. This megapixel 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.

1DX versus 750D MP

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, but the 750D provides a faster frame rate than the 1DX. It can shoot movie footage at 1080/60p, while the 1DX is limited to 1080/30p.

 

Feature comparison: Canon 1D X vs Canon 750D

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 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. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

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.

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.

Review summary: Canon 1D X vs Canon 750D

So how do things add up? Is there a clear favorite between the Canon 1D X and the Canon 750D? 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.
  • Richer colors: Generates images with noticeably better colors (1.1 bits more color depth).
  • Better low-light sensitivity: Requires less light for good images (1.6 stops ISO advantage).
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (14 vs 5 flaps/sec) to capture the decisive moment.
  • More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
  • Longer lasting: Can take more shots (1120 versus 440) on a single battery charge.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • More heavily discounted: Has been available for much longer (launched in October 2011).


Advantages of the Canon EOS 750D:

  • More detail: Has more megapixels (24 vs 17.9MP), which boosts linear resolution by 16%.
  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • More compact: Is smaller (132x101mm vs 158x168mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 996g or 64 percent) and is thus easier to take along.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (89 percent cheaper at launch).
  • 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 (11 : 9 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.

1DX 11:09 750D

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling 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 rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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.
