Autofocus problem with Nikon D7000 and Nikon 70-200 2.8 VR
I have a Nikon D7000 camera and using Nikon 12-24 f/4 and Nikon 17-55 f/2.8 lenses I had sharp photos. This spring I bought a used Nikon 70-200 f/2.8 VR lense. At 70mm it is sharp, but at 170-200mm I got blurry photos. After googling I found this good article: http://photographylife.com/how-to-quickly-test-your-dslr-for-autofocus-issues and followed this.
