I have a Nikon D800 and having no luck with focus when using a 2x teleconverter. I've tried both Sigma and Tamron 2x teleconverters on the following lenses. Sigma 70-200 2.8 (non OS version), Tamron 70-200 2.8 VC version, Sigma 120-300 2.8 (non OS version), Sigma 150mm 2.8 macro (non OS version). It will never lock focus, it just pumps back and forth forever hunting. They all work fine without the 2x. My older D300 worked fine with all of these combinations.

Any suggestions?

Yeah... buy a D850. 2x converters barely work with cameras that are really good at AF. A D800 is only passably good at AF.
