I completely get your point, I want my gear to be as good as possible. In general though, I want the gear we are paying lots of money for to work perfectly out of the box.
I hear ya, but I don't think it's reasonable to expect lenses to require no fine tuning out of the box, regardless of brand. As bodies are higher and higher resolution, the demands on lenses is more and more. I own a half dozen Nikon lenses and 3-4 "off brand" lenses. All require AF fine tuning for optimal performance on my D810.
Do you typically fine tune your lenses? With something that helps measure, like FoCal? Do all your lenses land on "0" fine tuning needed? At all focus distances?!? Even my Nikon lenses that require the least amount of fine tuning still show variance at various focus distances.
The benefit of Sigma's approach is, unlike all of my Nikon lenses, I don't need to compromise and pick one focus distance to tune to. With the Sigma dock, I can be "perfect" at all focus distances. Like I said a few posts ago, brilliant!
I suggest you take the time to read
this article from Roger at LensRentals.com. Especially this part:
"I've heard others state that only Sigma lenses need such a device. I'll meet them part way: I think there is probably a more frequent need for such adjustment on third-party lenses, but I can absolutely guarantee you that the big-boy's lenses do indeed have this same kind of problem, at least occasionally."
I hope this helps, and I hope you fine tune your lenses--Sigma, Nikon or otherwise. It makes a world of difference.
