Canon 77D vs T6i
The Canon EOS 77D and the Canon EOS Rebel T6i (labelled Canon 750D in some countries) are two digital cameras that were announced, respectively, in February 2017 and February 2015. 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 Rebel T6i? 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.
The physical size and weight of the Canon 77D and the Canon T6i are illustrated 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 size dimensions are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon T6i is somewhat larger (2 percent) than the Canon 77D. Moreover, the T6i is slightly heavier (3 percent) than the 77D. In this context, it is worth noting that neither the 77D nor the T6i 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. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will naturally be influenced heavily by the price. 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 T6i 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.
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. 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 more expensive and 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.
In terms of chip-set technology, the 77D uses a more advanced image processing engine (DIGIC 7) than the T6i (DIGIC 6), with benefits for noise reduction, color accuracy, and processing speed.
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 T6i have the same pixel density, as well as the same pixel size. It should, however, be noted that the 77D is much more recent (by 2 years) than the T6i, 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 corresponding ISO settings for the Canon EOS Rebel T6i are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 100-25600.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under review, the 77D has a notably higher overall DXO score than the T6i (overall score 7 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.9 bits higher color depth, 1.3 EV in additional dynamic range, and 0.1 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 are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the 77D provides a higher frame rate than the T6i. It can shoot video footage at 1080/60p, while the T6i is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. The 77D and the T6i 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 table below summarizes some of the other core capabilities of the Canon 77D and Canon T6i in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 77D, but is missing on the T6i 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 has 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 T6i 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.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Canon EOS 77D and Canon EOS Rebel T6i and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

The 77D is a recent model that features in the current product line-up of Canon. In contrast, the T6i has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the T6i was succeeded by the Canon T7i. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So what is the bottom line? Which of the two cameras – the Canon 77D or the Canon T6i – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Canon EOS 77D:
- Better image quality: Scores markedly higher (7 points) in the DXO overall assessment.
- More dynamic range: Captures a larger spectrum of light and dark details (1.3 EV of extra DR).
- Better jpgs: Has a more modern image processing engine (DIGIC 7 vs DIGIC 6).
- Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
- Easier setting verification: Features an LCD display on top to control shooting parameters.
- Faster burst: Shoots at higher frequency (6 vs 5 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Longer lasting: Can take more shots (600 versus 440) on a single battery charge.
- Easier wireless transfer: Supports Bluetooth for image sharing without cables.
- More modern: Reflects 2 years of technical progress since the T6i launch.
Reasons to prefer the Canon EOS Rebel T6i:
- More affordable: Was released into a lower priced segment (17 percent cheaper at launch).
- More heavily discounted: Has been around for much longer (launched in February 2015).
If the count of individual advantages (bullet points above) is taken as a guide, the 77D is the clear winner of the match-up (10 : 2 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. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

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 shooting experience and imaging performance when actually working with the 77D or the T6i. 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 expert reviews 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], digitalcameraworld [DCW], 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.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
