I bought the Canon EOS 80D when it came out and used it ever since. I am very satisfied and have never had any problems with it. I am a long way from a technical photographer, but obviously like when it gets good pictures. And it will.
Focusing is fast in both viewfinder mode and display mode, making it easy to capture images in poor light conditions and on fast moving objects. The different focus modes, which among other things let the focus follow with moving objects, are smooth.
The camera can be connected to the mobile phone via wifi, which is smart when you want to quickly transfer pictures and share on, for example, Instagram.
The camera is comfortable to hold even for extended periods. However, heavy lenses make the front end just like other cameras. The handle also creakes slightly just below the trigger button, which is annoying. I've heard that others have had similar problems and got their camera replaced, but I haven't bothered about it.
The display is clear even in bright sunlight and keeps good quality. It makes it easy to determine if an image has become sharp. On the other hand, it has a tendency to reinforce some highlights, which sometimes makes it difficult to determine whether an image has been properly exposed. Often, this causes me to under-expose, which I have to correct afterwards in the image editing program.
Overall, I recommend this camera. It suits anyone who is interested in photography and wants to take a step up from the cheaper entry cameras, but is not prepared to throw in much more expensive full-format cameras.
