When I set my lens to MF on my 60D, the AF is off but you still can see the red indicator light and hear the beep sound when you point at the hyperfocal point. Went down to canon service center and tested other camera like 60D, 7D and 5D, all have the same function. Try on Nikon and their is total off. Canon said that it tell you that you are in focus. Do anyone face the same issue? Will this affect the IQ?
