Canon 77D vs 850D

The Canon EOS 77D and the Canon EOS 850D (labelled Canon T8i in some countries) are two digital cameras that were officially introduced, respectively, in February 2017 and February 2020. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. Both cameras offer a resolution of 24 megapixels.

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 77D and the Canon EOS 850D? 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.

Body comparison

The physical size and weight of the Canon 77D and the Canon 850D are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.

Size Canon 77D vs Canon 850D
Compare 77D versus 850D top
Comparison 77D or 850D rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 850D is somewhat larger (3 percent) than the Canon 77D. However, the 850D is markedly lighter (5 percent) than the 77D. In this context, it is worth noting that neither the 77D nor the 850D are weather-sealed.

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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Canon EF Lens Catalog.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The 850D was launched at a somewhat lower price (by 17 percent) than the 77D, which makes it more attractive for photographers on a tight budget. 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

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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature an APS-C sensor and have a format factor (sometimes also referred to as "crop factor") of 1.6. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Technology-wise, the 850D uses a more advanced image processing engine (DIGIC 8) than the 77D (DIGIC 7), with benefits for noise reduction, color accuracy, and processing speed.

Canon 77D and Canon 850D sensor measures

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 24 megapixels. This similarity in sensor specs implies that both the 77D and the 850D have the same pixel density, as well as the same pixel size. It should, however, be noted that the 850D is much more recent (by 2 years and 11 months) than the 77D, and its sensor will have benefitted from technological advances during this time.

The Canon EOS 77D has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 100-51200. The Canon EOS 850D offers exactly the same ISO settings.

77D versus 850D 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"). The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

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 850D provides a better video resolution than the 77D. It can shoot movie footage at 4K/24p, while the 77D is limited to 1080/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The 77D and the 850D 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 viewfinders of both cameras offer the same field of view (95%), as well as the same magnification (0.51x). The following table reports on some other key feature differences and similarities of the Canon 77D, the Canon 850D, and comparable cameras.

One feature that is present on the 77D, but is missing on the 850D 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 cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.

The Canon 77D and the Canon 850D both have an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

Concerning the storage of imaging data, both the 77D and the 850D write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

Review summary

So what is the bottom line? Is the Canon 77D better than the Canon 850D or vice versa? The listing below highlights the relative strengths of the two models.


Arguments in favor of the Canon EOS 77D:

  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More heavily discounted: Has been available for much longer (launched in February 2017).


Reasons to prefer the Canon EOS 850D:

  • Better jpgs: Has a more modern image processing engine (DIGIC 8 vs DIGIC 7).
  • Better video: Provides higher definition movie capture (4K/24p vs 1080/60p).
  • Faster burst: Shoots at higher frequency (7.5 vs 6 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (800 versus 600) out of a single battery charge.
  • More affordable: Was released into a lower priced segment (17 percent cheaper at launch).
  • More modern: Reflects 2 years and 11 months of technical progress since the 77D launch.

If the count of individual advantages (bullet points above) is taken as a guide, the 850D emerges as the winner of the match-up (6 : 3 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. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

77D 03:06 850D

How about other alternatives? Do the specifications of the Canon 77D and the Canon 850D 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the 77D and the 850D 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.

Expert reviews

This is why hands-on reviews by experts are important. 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted 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 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.
