That can't be defended. That lens will always be a tight-fit, there's no
"break-in" that will occur. To insinuate that it would loosen up was not
right. It would have been simple to say that they'd just get another lens
off of the shelf for you. I would have undoubtedly returned that one, it
was far too tight.

It might have eventually loosened up. But, if the fitting on my camera was
softer than the metal on the Sigma, I would have had a major problem. After
lunch I went to Nikon and they thoroughly checked the fittings. We even
tried other Nikon Lenses on other bodies. All was according to specs.
Eventually sigma will get the message. But, since they do not have me on
board as a consultant, I have no reason to spend to spend any more time on
this issue.

Tamron has also moved into Sony.
