I can't say enough good things about Buydig service it was excellent. They sent me an RMA and a return label and credited my account right away. I have been a Buydig customer for years and this is the first time I have had to return anything. The lens gets two stars but Buydig gets Five!
Well made; solid build
Focus problems that Nikon could not determine why or figure out how to correct; It continuously back focused and since my particular camera does not have adjustment for that, subjects were always soft if they were at any distance; Ran any number of tests and this lens continued to underperform.
