After using the camera for a couple of weeks, I ordered the M-22mm lens and the EOS lens adapter. I have a couple of older small kit lenses with longer zooms that work well on the M6. And I wanted the 22mm prime for night/low-light shots. The M lenses are so light and tiny they're super-easy to carry around. I'm leaving in a few weeks for Japan and Korea and I'm looking forward to putting this camera through its paces. Plus, it weighs only about one-fourth of my 7D with lens but is capable of similar high quality photographs.
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. <<
