Canon 1D X Mark II versus Canon T7i

The Canon EOS-1D X Mark II and the Canon EOS Rebel T7i (labelled Canon 800D in some countries) are two digital cameras that were announced, respectively, in February 2016 and February 2017. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (1DX Mark II) and an APS-C (T7i) sensor. The 1DX Mark II has a resolution of 20 megapixel, whereas the T7i 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 Mark II vs Canon T7i

The side-by-side display below illustrates the physical size and weight of the Canon 1D X Mark II and the Canon T7i. Three consecutive perspectives from the front, the top, and the back are presented. All size dimensions are rounded to the nearest millimeter. You can also use the toggle button 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 Mark II – represents the basis or 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 T7i is considerably smaller (51 percent) than the Canon 1D X Mark II. Moreover, the T7i is substantially lighter (65 percent) than the 1DX Mark II. It is worth mentioning in this context that the 1DX Mark II is splash and dust resistant, while the T7i 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 Mark II) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (T7i). You can find a comprehensive overview of suitable optics in the Canon EF Lens Catalog.

Concerning battery life, the 1DX Mark II gets 1210 shots out of its LP-E19 battery, while the T7i can take 600 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 T7i was launched at a markedly lower price (by 88 percent) than the 1DX Mark II, 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 Mark II vs Canon T7i

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 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon 1D X Mark II features a full frame sensor and the Canon T7i an APS-C sensor. The sensor area in the T7i 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 Mark II and Canon T7i sensor measures

Despite having a smaller sensor, the T7i offers a higher resolution of 24 megapixel, compared with 20 MP of the 1DX Mark II. 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 6.57μm for the 1DX Mark II). However, it should be noted that the T7i is a somewhat more recent model (by 1 year) than the 1DX Mark II, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.

For most 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").

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the 1DX Mark II provides a higher video resolution than the T7i. It can shoot video footage at 4K/60p, while the T7i is limited to 1080/60p.

 

Feature comparison: Canon 1D X Mark II vs Canon T7i

Apart from body and sensor, cameras can and do differ across a variety of features. The 1DX Mark II and the T7i 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 Mark II and Canon T7i in connection with corresponding information for a sample of similar cameras.

If the number of relative strengths (bullet points above) is taken as a guide, the 1DX Mark II emerges as the winner of the contest (10 : 7 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 Mark II 10:07 T7i

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the 1DX Mark II and the T7i in practical situations. 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 hands-on reviews by experts are important.

The above review scores should be interpreted with care, 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
