[QUOTE="Love Nikon, post: 440106, member: 38179"] I have had similar refusal to focus problems with a 18-140 and 7100. When I buy a lens I set the back focus and test it ... BUT have found that with a new lens it runs in and the back focus moves ..now I know/think this should not affect the focus modules ability to lock but both the 18-140s I own changed from +12 to -5 and an 28-300 changed from +5 to 0. The 18-140 now both work perfect .I have a card with letters and lines at 35% grey to test for the problem ..worth checking your BF after a few hundred shots... [/QUOTE]
