You should know that both these two cameras Canon T7i and Canon 77D have been announced together at the same time and if you are looking at the table you can see that both of these two have almost same specifications. So, when you see the similar specifications in two cameras and you have to buy one of these two then creation of confusion in your mind is inevitable.

Now the real question is which one to buy between these two? Well, Canon T7i/800D as well as Canon 77D both have same APS-C sized sensor and number of effective pixels are also same, which clearly means that both of these two cameras snap the images with stunning details and crystal clarity.
And thankfully, both use the incredible and Canon’s own proprietary “Dual Pixel CMOS AF system” that promises you to offer blazing fast AF performance in whatever situation. Let’s discuss you the advantages and working theory of this outstanding AF system – A very innovative AF technology that allows both capture video in Live View with smooth and precise autofocus. Not only this, this game-changing AF technology provides fast and accurate autofocus during Live View still image capture. Actually, CMOS sensor on 77D has two photodiodes per pixel (Total 40 million) and each pixel on the sensor performs both phase-difference detection autofocus and capture light. On the other hand, Phase-difference detection AF, enabling the cameras to achieve quick and easy auto focus. Furthermore, due this innovative AF system the camera gets autofocus on approx 80% of the image plane that eventually confirms you get images with stunning details.
Furthermore, both cameras allow you capture Full HD Video (1080p) recording at 60fps. After all, Canon T7i as well as 77D avails faster shutter speed of 1/4000 sec, 6fps continuous shooting speed and even the same number of shots one can take from both cameras.
But one advantage of buying 800D/T7i is that it is lesser expensive than Canon 77D, but 77D with its kit lens give you maximum telephoto reach of around 210mm, whereas Canon 800D offers you 88mm only with its kit lens etc.
These were the basic difference we have light out and the further decision is yours.
