I had a problem with my Tamron 90 macro when using LiveView on my D800. It chattered and acted erratic. Worked fine on my D90. I sold the Tammy and got the Nikon 105VR. Not all third party lenses are necessarily compatible with Nikon bodies and it's up to the third parties to make firmware changes to their lenses. I just didn't want to deal with that and wanted a 105VR anyway. Hope it works out for you.
