Shooting movies is also great now with the servo AF feature. My T3i required that I manually focused while shooting movies. With the servo AF, the camera will actually follow the moving subject adjusting the focus on the fly. I mean, your cell phone can do it and so could my point-and-shoot Canon camera, but their old DSLRs actually didn't have that feature, but now (well, since like the T5i I think) they do and it's very useful. Speaking of movie mode, I very much like that they added another step in the power switch for movie mode instead of requiring you to turn the knob all the way to the very end to get to movie mode. Now you simply flip the switch to it.
With the 'Recorder' you can record your screen (Full screen or specific area) it will capture your gameplay sound as well as your own voice if you use a microphone (There is an option to disable it). The resolution and frame rates are really good, I'm also amazed that they included a 'webcam record' as well as PIP where you can include both the webcam recording with the game play recording together.
Apple iMovie is the ultimate Mac video app for novice filmmakers, combining professional trailers and themes,abundant special effects and an easy-to-learn interface. Version 10.1 added 4K editing and sharing, as well as extended handling to video shot at 1080p and 60 fps. Recent updates tweaked the interface and added Touch Bar support for the latest MacBooks.
The T#i line is what they call a "pro-sumer" line, which is basically between a consumer line camera like a very basic DSLR and a professional DSLR camera, thus the term "pro-sumer." Typically what this meant is an DSLR with an APS-C sized sensor, decent resolution, and some hand-me-down professional features of pro-grade cameras from a few years ago. For this reason, sometimes it's not worth upgrading from one of these cameras to the next until at least a few generations have past (meaning if you have a T5i, it's not really a giant leap forward to upgrade to a T6i). However, the T7i is somewhat different. When I was doing research on what features it has and what it is missing compared to the pro-grade DSLRs that are considered "current" right now, I was surprised to find very little. The main differences really is that the pro-grade cameras have the LCD display on the top that would display all of your relevant camera settings, and then a few of them would also sport a full-frame sensor. Other than that, the differences are very minor. Something like maybe 1 or 2 frames less in burst mode or something like that. Nothing that would really jump out at you and make you regret not stepping up to the professional grade equivalent (Think it would be the 77D?). It actually has pretty much all of the big features of even their current pro-grade DSLRs, making the T7i probably one of the best prosumer DSLRs to buy.
