I just read the white paper on the Mark IV and this looks like a really great camera, if it does what its designed to do. I am especially interested in the spot focus points. But, my biggest, biggest, biggest complaint about Canon vs. my old Nikon days, is that I have always found the AF tracking to be useless since it didn't keep the active focus point lit. Without that indicator, you had no idea if you were still tracking the correct subject and so everyone pretty much uses center focus point when shooting sports. In reading the white paper, I am hopeful that this is no longer the case.
So does the Mark IV keep the active focus point lit when using the focus tracking modes? None of the prior 1 Series bodies did this, and Nikon's pro bodies have done it for years.
