I just got a used 5D in from Adorama and before I send it back I'd like to make sure it's not an easy focus screen fix issue. All the AF points except for the furthest right one don't light up. I could have sworn I've seen a thread on this in the past that it was simply the focus screen not installed properly but I can't find it and a google search hasn't been helpful.
Any other thoughts other than "it's broke"?
Thanks!
