Newbie here. I'm writing in to see if anyone can help me figure out this strange issue I'm having with my D90. I originally only had one long zoom and I noticed that the autofocus wasn't working well unless I was zoomed all the way in. It was a pain, but I could get around the issue by zooming in, locking focus, and then zooming out (or of course, manually focussing). I recently picked up a wide zoom (12-24 Tokina) and I found that the autofocus struggled again.
I printed a focus chart and took some shots to test out what was happening. As I suspected, the autofocus worked well so long as I was zoomed in all the way with my 18 to 200 zoom (I know, not a great lens). When zoomed out it was always soft. I switched to my wide zoom and it was always soft, so I know it's not a lens issue, but beyond that I'm at a loss, and hoping to avoid going the costly and timely route of getting my camera fixed by Nikon.
Any help would be appreciated!
