Canon 6D Mark II versus Canon T7i

The Canon EOS 6D Mark II and the Canon EOS Rebel T7i (labelled Canon 800D in some countries) are two digital cameras that were officially introduced, respectively, in June 2017 and February 2017. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (6D Mark II) and an APS-C (T7i) sensor. The 6D Mark II has a resolution of 26 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 6D Mark II vs Canon T7i

An illustration of the physical size and weight of the Canon 6D Mark II and the Canon T7i is provided in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All size dimensions 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 side – the 6D Mark II – represents the basis for the calculations 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 notably smaller (18 percent) than the Canon 6D Mark II. Moreover, the T7i is markedly lighter (30 percent) than the 6D Mark II. It is worth mentioning in this context that the 6D 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 6D 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 6D Mark II gets 1200 shots out of its LP-E6N 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 63 percent) than the 6D 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 6D Mark II vs Canon T7i

The size of the imaging sensor is a crucial determinant 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon 6D Mark II features a full frame sensor and the Canon T7i an APS-C sensor. The sensor area in the T7i is 61 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 6D Mark II and Canon T7i sensor measures

With 26MP, the 6D Mark II offers a slightly higher resolution than the T7i (24MP), but the 6D Mark II nevertheless has larger individual pixels (pixel pitch of 5.76μm versus 3.72μm for the T7i) due to its larger sensor. Moreover, the 6D Mark II is a somewhat more recent model (by 4 months) than the T7i, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

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. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (1080/60p).

 

Feature comparison: Canon 6D Mark II vs Canon T7i

Apart from body and sensor, cameras can and do differ across a range of features. The 6D 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 adjacent table lists some of the other core features of the Canon 6D Mark II and Canon T7i 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.

Both the 6D Mark II and the T7i are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The T7i replaced the earlier Canon T6i, while the 6D Mark II followed on from the Canon 6D.

Review summary: Canon 6D Mark II vs Canon T7i

So what is the bottom line? Is the Canon 6D Mark II better than the Canon T7i or vice versa? Below is a summary of the relative strengths of each of the two contestants.


Arguments in favor of the Canon EOS 6D Mark II:

  • Better low-light imaging: Features bigger pixels on a larger sensor for better high-ISO images.
  • Easier setting verification: Has an LCD display on top to control shooting parameters.
  • Longer lasting: Can take more shots (1200 versus 600) on a single battery charge.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • More modern: Is somewhat more recent (announced 4 months after the T7i).


Advantages of the Canon EOS Rebel T7i:

  • More compact: Is smaller (131x100mm vs 144x111mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 233g or 30 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 (63 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in February 2017).

If the number of relative strengths (bullet points above) is taken as a guide, the match-up finishes in a tie (5 points each). 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.

6D Mark II 05:05 T7i

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the 6D Mark II or the T7i handle or 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 hands-on reviews by experts are important.

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. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
