Re: Issue with Sigma 17-50mm f/2.8 ex dc os hsm when using with D7100

The problem with OS remaining on is the outward manifestation of the fact that Sigma and Nikon are not playing well together. We don't know what other issues exist that we don't see immediately. For example, many of the folks who have bought these lenses, myself included, have also experienced seemingly random focus problems.

I find it interesting that, while Sigma was not a true competitor in terms of build quality (and in most cases) image quality, there were no interoperability problems. Sigma generally only made a few lenses where the IQ was on a par with Nikon and only in ranges (the 150/2.8 macro, for instance) where Nikon had holes.

Now that Sigma has shored up their QC, improved the build and is not only directly competing with Nikon but is actually besting them in some spots (the 18-35/1.8 and 50 Art come to mind), suddenly these issues crop up.

To compound matters, there is significant pressure on core products from manufacturers who used to be on the periphery (Sony, Fuji) as well as on the core format from former outliers like micro four thirds.

Added up, it seems reasonable that Nikon might not be as generous to those who are taking the food from their mouths.
