Canon has a diverse range of cameras to offer, making sense of which can sometimes be taxing. Even with the simple formula of, higher the number, newer the model, getting the exact specification differences between generations can be a little difficult. There might be tiny alterations in a later model, which might not be apparent in an overview. We are going to meticulously compare the Canon T6i vs T7i in this article. 

If you are a beginner looking for a camera to kick-start your photography, both of these models will appear on your search radar. Both are DSLR cameras offering a 24-megapixel resolution APS-C sensor. The decision of picking one can be confusing, keeping in mind how similar they look from a distance. 

Even physically, with an almost identical control layout, same viewfinder, and 3-inch display, the camera bodies look quite similar. However, the devil is in the details. Therefore here we’ll take a look at every minor yet note-worthy difference and similarities in both the models.

canon t6i vs t7i

Nomenclature And Release

Let’s start off with the exact names and family of the cameras. The Canon T6i or Canon EOS Rebel T6i (aka Canon 750D in some parts of the world) was released in February 2015. The Canon T7i, short for Canon EOS Rebel T7i (called Canon 800D in some regions) was launched in February 2017. There is an age difference of 2 years between the cameras which accounts for minor changes in the specs. 

As evident from the names, they both identify as a part of Canon’s Rebel line of DSLRs. The rebel range is hugely popular and plays a major role in the dominance of Canon in the digital camera market. Their success can be attributed to their camera range inheriting a lot of the sensor and shooting technology from professional DSLR cameras released earlier. 

They are yet available at a very pocket-friendly budget. The comprehensive EOS system of compatible accessories and lenses also contribute to the charm of the Rebel line.

Physical Features

1) Weight

Here we compare the body weight, looks, and features for Canon T6i vs T7i. The Canon T6i weighs 1.22lb or 555g, whereas the Canon T7i is slightly lighter (23 grams / 4 percent lighter) at 1.17lb or 532g, both calculated including batteries and excluding lenses. However, this weight distinction doesn’t make much of a difference in performance. 

2) Dimensions

The external dimensions of Canon T6i are 132mm X 101mm X 78mm or 5.2” X 4” X 3.1” (width X height X depth). The Canon T7i is approximately 2 percent smaller than the Canon T6i, if the front area (height X width) is considered as the average size measurement. It has the external dimensions of 131mm X 100 mm X 76 mm or 5.2” X 3.9” X 3” (width X height X depth). 

3) Lens-compatibility

While buying a camera, the number of interchangeable lenses compatible with your device is a big deciding factor. Both Canon T6i and T7i contain the same lens mounts – Canon EF/EF-S, being compatible with all the same lenses. This leaves them with a wide option of 326 native lenses that can fit. 

You might also want to choose a lens with optical stabilization as both the camera bodies don’t have sensor-based image stabilization. That leaves you with about 112 lenses that can do the same. 

4) Weather-sealing

The build material of both the cameras is not weather-sealed. Therefore, you need to be careful while using them outdoors, for example, taking a protective covering if it starts raining. 

5) Display Screen

Canon T6i and Canon T71 both have LCD screens with the same size – a 3” diagonal. Their screen is fully articulating where the screen angle can be changed to make it easier to shoot at levels below the waist or above the head. This feature comes very handily in many scenarios – taking selfie shots, videos, or very low angle pictures. The screens can be touch-operated, having a resolution of 1040 pixels and are swivel attached. 

Sensor Comparison

One of the key determining factors of image quality in a digital camera is the size of the sensor. Larger sensors give the photographer more creative options allowing them to achieve a shallower depth of field so as to separate the object from the background. 

Large sensor cameras even offer richer color depth, low-light sensitivity, and wider dynamic range as they have bigger individual pixel-units. On the other hand, it also has limitations such as larger sensors that come with heavier and bigger lenses and cameras and tend to be more expensive.

Considering Canon T6i vs T7i with respect to sensor size, both share the same size and resolution of 24 megapixels. This similarity implies that both the cameras have identical pixel size as well as pixel density. However, because of the 2-year gap, Canon T7i is more recent and, therefore will have benefitted from better technology over that time. 

Both Rebel T6i and Rebel T7i have an APS-C sensor and a format factor or a crop factor of 1.6. This puts the cameras among those with medium-sized sensors that try to strike a balance between portability and image quality. Their sensor width to height ratio or native aspect ratio is 3:2. 


Technically speaking, Canon T7i uses DIGIC 7 which is a more advanced image processing engine as compared to Canon T6i which uses DIGIC 6. This also helps in better color accuracy, processing speed, and noise reduction. 

If you need to shoot a moving scene or action, be it your kid’s soccer game or air racing, Canon T7i has a benefit of a better autofocus system. It contains 49 points in contrast to Canon T6i offering 19, which provides quite a bit of flexibility.

One battery charge goes for about 600 pictures in T7i and about 400 in T6i.


ISO measures the sensitivity of the image sensor of the camera. It is the setting that helps brighten up pictures in low-light or dark environments. The higher the ISO number, the brighter the picture will be. 

The Canon T6i native sensitivity range of ISO 100 to ISO 12800 that can be stretched to ISO 100 to ISO 25600. Correspondingly, the Canon T7i has ISO setting that ranges from ISO 100- ISO 25600 that can be extended to ISO 100 TO ISO 51200.

Shutter Speed

The shutter speed of a camera is the duration of time for which the shutter of the camera opens to take a picture by letting light into the optical sensor. It can also be thought of as the time your camera takes to take a picture. It can be manipulated by the shutter setting wheel on the camera. 

A faster shutter speed helps capture fast-moving objects like a bird flying by or a person mid-jump in the air, by exposing light to the sensor for a fraction of a millisecond.

Slower shutter speeds let the light in for a longer period of time taking in everything that happened in the frame for the whole amount of time. This creates a blurred effect giving the effect of motion like in bike advertisements. Allowing light for more time also can help capture low or distant light objects like stars at night.

Both the cameras have the fastest shutter speed of 1/4000s, with the T6i shooting 5 frames per second and T7i shooting 6 frames per second in continuous shoot mode. They also have a built-in flash for night photography. The 1 fps difference might not sound like a lot, but it is actually a 20 percent increase, which can be the borderline between missing an action shot or perfectly nailing it.

Input/ Output Connections

The extent of communication of a camera with its environment can be a significant aspect in deciding a camera, for some imaging applications. Considering the interfaces they provide for data transfer and accessory control, both the cameras have connection options such as hot shoe port, internal microphone, internal speaker, microphone port, headphone port, HDMI port, USB port, Wifi support, and NFC support. The only difference relating to communication is that T6i doesn’t offer Bluetooth connection support, whereas T7i does. 

The cameras, though discontinued now, can be found regularly on eBay. The T7i replaced the T6i, and the Canon T8i replaced the T7i. Although, any additional information regarding them including user manuals and guides, related accessories can be found on the official website of Canon.

Picture Quality

Talking about image quality in Canon T6i vs T7i, both have the same resolution, which is approximately 24 megapixels but T7i has a sensor that is an entirely different unit, inheriting its origin from Canon 80D. It brags about an improved low-light shooting as its ISO settings can be increased up to ISO 51200, which is higher than what is possible in T6i (up to ISO 25600). It offers improved dynamic range as well, contributing to preserving detail in high contrast (like a bright sky on a sunny day with very dark shadows on the ground).

Anyways, these differences, in practicality, might have a bit of effect on the perceptual picture quality in most of the situations. To fully take advantage of the sensor in any of these cameras, you will have to shoot in RAW. However, beginners will find it easier to stick with JPEGs simply. 

A RAW file type can be changed to bring out the maximum details of a picture, but a JPEG isn’t easy to manipulate. Therefore, you might not notice any difference in the sensors unless you are ready to put in some extra work. 

Video Shooting

Cameras nowadays don’t just capture still pictures but also are capable of making video footage. Although both the cameras have sensors equipped with a high read-out speed for images in motion, in the race of Canon T6i vs T7i, the latter gives a faster frame rate than the former. 

T7i has the capacity to shoot footage at 1080/60p, whereas T6i is restricted to 1080/30p, which means both the cameras in consideration can shoot in full HD 1080p video. The Canon EOS Rebel T7i can shoot at up to 60 frames per second as opposed to Canon EOS Rebel T6i which only allows 30 frames per second. 

However, neither of the two is adept at winning accolades for their video quality, especially when many other cameras offer 4K resolution for videos. So it seems

This feature of T7i can be attributed to its new sensor, which uses Canon’s improved on-chip phase detection technology, also known as DPAF (Dual Pixel Autofocus). Traditionally DSLRs are very slow to focus when in live view mode (the setting required to shoot videos). The introduction of DPAF has helped change the game. 

The smoothness and accuracy make it feel like you are shooting video on a camcorder. It makes small projects like recording home movies almost effortless, so it might be a good option to pick T7i over T6i if you are going to shoot a lot of basic videos.

For the most part, both Canon Rebel T6i and Canon Rebel T7i share identical interfaces. Having a look at the exterior buttons, only one significant difference can be noted- the presence of a wireless connectivity shortcut key at the back of the Rebel T7i. Both of them offer NFC and Wi-Fi but T7i uses Bluetooth too for a hassle-free connection to Canon’s mobile app. 

As far as software is considered in Canon T7i vs T6i, the former has a very unique feature- a guided menu system called Feature assistant by Canon. It helps the new users get up and running as fast as possible. It involves a simplified version that explains the various shooting modes with pictures and easy plain-English descriptions, replacing the standard user interface of Canon. 

It is specifically designed keeping in mind the touch interface, making it very welcoming to the new generation of photographers who are used to clicking pictures on smartphones.  However, experienced photographers can turn off the Feature assistant followed by T7i reverting the interface to standard, so, you have nothing to lose.

Comparing Notes

1) Similar Features

Moving on to the various features in both the cameras, T6i and T7i both have an optical viewfinder. It helps get a clear image to frame even in brightly lit surroundings. Viewfinders in both the cameras provide the same magnification (0.51X) and identical field of view (95%). 

Both the cameras feature an articulated rear screen which turns into front-facing if required. This is desirable for photographers or vloggers interested in shooting in selfie mode.

The storage of both the cameras has their imaging data files written onto SDXC cards. They are also capable of using UHS-I cards, providing for Ultra High Speed transfer of data that goes up to 104 MBps.

Other features to be taken into consideration, which both of the cameras have similarities in are external flash shoe (good for night photography), RAW support (better image quality), face detection focus (handy in portrait photography), smartphone remote (camera can be operated through the smartphone), AE bracketing (useful for tough lighting conditions and HDR), webcam function (camera can be used as a webcam), anti-flicker (reduced exposure and uneven color under flickering light). 

2) Differences

Let’s have a quick recap of the differences in both cameras in the comparison of Canon EOS T6i vs T7i. T6i has been in the market for a longer time than T7i hence it comes heavily discounted in contrast.

However, T7i seems to have the upper hand in all other aspects. It gives better JPEGs because of the DIGIC 7 processing engine and better video quality with a higher movie frame rate (1080/60p). A higher frequency of shooting gives a faster burst speed, therefore capturing movement better (6 frames/sec). It lasts longer with a single battery charge getting about 600 shots. Bluetooth support enables easy wireless transfer of images which isn’t present in the T6i.

Type Of Photography Possible

Both Rebel T6i and Rebel T7i are entry-level cameras suitable for the beginner entering the realms of photography. They have all the basic traits required to start learning to work with DSLRs. A wide range of basic photography can be achieved using both the cameras but if we have to go deeper into the details, here are the categories. 

With almost identical features available in both that are required in the type of photography, both cameras draw a tie in portrait, street, landscape, and generic photography. But with 45 focus points (26 more than in T6i) and a slightly faster burst speed, T7i looks like a better choice for sports photography. 

Canon t6i vs t7i – Final Words

Feature comparisons clearly declare T7i as the winner in the Canon EOS Rebel T6i vs T7i race. But it isn’t that huge of a difference that demands you to go for the Canon T7i if you already own the T6i. However, the importance of individual strengths varies from photographer to photographer. 

For instance, a wildlife photographer will not hold desirable features that are relevant to a wedding photographer or a fashion photographer. Hence, the decision of picking a camera is very personal.
