Hi Bro fatigue,
I got this problem with my D40 cam. With a 18-70 lens, working fine. But when I mount a 85mmF1.8, there is an error message asking me to turn the aperture ring to the smallest aperture (biggest F number). After doing that, still got problem. Tried a 28-80G lens, no problem. Looks like it's OK with G lens, but not D lens. Do you think you can help. Also, noticed that when I mounted the 85mm lens, felt a greater resistance to arrive at the locking click.
