"This, the element I found most difficult to get my head around, was the thing that in the end I fell most in love with – there are 5,655 selectable AF positions with touch and drag, that’s incredible to me. Heading out for shoots in recent weeks since I’ve returned the Canon EOS R, I have found myself a little frustrated with the constraints of using the joystick on my Canon EOS 1DX Mark II."
