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 officially introduced, 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

The side-by-side display below illustrates the physical size and weight of the Canon 1D X and the Canon 750D. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth dimensions are rounded to the nearest millimeter. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative 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.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Canon 1D X vs Canon 750D

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color depth than smaller pixel-units 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 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.

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

For many cameras, data on sensor performance has been reported by DXO Mark. 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 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, 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 adjacent table lists some of the other core features of the Canon 1D X and Canon 750D along with similar information for a selection of comparators. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

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? A synthesis of the relative strong points of each of the models is listed below.


Advantages of 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: Has 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.
  • 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).


Arguments in favor 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 relative strengths (bullet points above) is taken as a measure, the 1DX comes out slightly ahead of the 750D (10 : 9 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision.

1DX 10:09 750D

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 1DX or the 750D. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable. This is why hands-on reviews by experts are important. The table below summarizes the assessments of some of the best known 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
