Nikon AF-S 300mm F4 and Tamron 140F - FNs 1.4X converter - autofocus won't work
I am trying the combination of the 300 F4, with the tamron 1.4 pro converter on a D100. The problem is that autofocus does not work. As the aperature is 5.6, I thought that it should.
Has anyone else tried this? what was the results?
