I won’t hide the fact that I’m a Canon fanboy. Canon just gets a lot of things right. Many of them are, in my books, the most important things, like great color science (images look beautiful and skin tones are rendered organically), the aforementioned stellar auto-focus (after all, what use is an out of focus photo or video?), and long battery life so you can shoot for hours without worry.
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. <<
