In theory that's impossible.
Originally posted by dlacouture effect on contrast AF, but I had to check everything), and to my surprise, "Apply to One" was showing "unset" with my 70-200, instead of the usual "0"... WTF?
That's normal. The camera shows "unset" for lenses that you haven't calibrated yet (so "unset" kinda means "factory 0").
Originally posted by dlacouture I successfully changed it to "0", but contrast AF is still back-focusing...
Are you sure you're focusing on exactly the same object with contrast AF as with phase AF? Make sure the rectangle on the LV screen is on the same object/location as the phase AF sensor and that you're not using the face detection (may think it found a face in the background?
). Of course use a flat object.
