Now one big question I know is on everyone's minds. APS-C or Full-Frame? Now the obvious answer is that if you're making money with the camera, go full-frame, if not, APS-C. But actually it's not that simple. First, there's no reason someone doing photography as a hobby shouldn't get a full-frame camera, other than the fact that they cost a whole lot more. But if you can afford it and you want the advantages of a full-frame camera (better resolutions, better low-light photography, etc.) and you don't mind the extra bulk, then why not? And on the flip-side, if you're a pro and want a smaller, less bulky camera to take with you on a shoot, then there's also no reason to say an APS-C camera will not be worth buying... But since you're looking at the T7i, let me go over a few actual advantages to an APS-C camera regardless of your status as an amateur or professional.
The second big draw is communication. The app creates a unified inbox for comments on Facebook and Instagram and messages from Messenger, so that you don’t have to bounce between different apps in order to respond to people. The app doesn’t seem to cover every possible messaging vector inside of Facebook’s services, but it sounds like a handy start. <<
