I can personally vouch that this camera is phenomenal.
Has an inbuilt wifi, making it easy to use your mobile as a remote.
The likely upgrade to this is going to be 2020 and beyond (would also be quite expensive). Given Canon's upgrade cycle.

This is a grey import unit and as such price is not comparable to Teds, CameraPro etc. Usual grey importers have this at a similar price if you really feel like gambling $3.5K.
