Occasional bird snapper
Use Av mode for the aperture you want and then go into the 'ISO speed settings' menu and set the minimum shutter speed you require. You can also do this on the 5D3 but the range of shutter speeds available are a lot less than on the 7D2. I do not know about the 1Dx.Tell me how Roy !
Using this method you can use whatever metering mode you want and also use Ev comp as per normal.
