I decided to return the lens. I called B&H today and they were very accommodating. Yesterday I tried using an average fine tuning number, a fine tuning adjustment that favored longer focal lengths and an adjustment favoring short focal lengths. None of these options were acceptable to me. If the new lens is not up to snuff I may try the tamron or 16-85 Nikon (last option, I know this one is sharp but I need 2.8.). Thanks for the help and suggestions…This is a great board.
