Canon, and yes you do, the camera is not recognized without the drivers installed. Actually, it barely works even with the drivers installed. There is a free version that I have had working in the past, to glorious success, with the Canon 1DX, but the current 5Div does nothing, and I don't want to pay to find out that it still doesn't work.

There's half a camera's worth of features in these things that people won't use, but they still pay for them.
