Hi Al, Does the D3s focus with the 1.4 TCE and the Nikon 80-400? Do you have the old 80-400 or the new one? There are no general rules about TCs and autofocus–whether the rig will focus depends on the camera, the lens, and the TC. As my 70-200 is an f/2.8 lens the 2X II TC brings it to f/5.6. All Canon cameras focus at effective apertures of f/5.6 or larger so yes, my new favorite rig not only autofocuses with the 2X TC but all of my AF sensors are selectable. See you in San Diego in JAN. It should be a great year.

Am I behind the times?
One of the camers I use is the Nikon D3s with the Nikon 80/400 and a 1.4x tc.
I remember that any Teleconcerter above 1.4 cannot be used with Auto Focus.
My question, Does the 2×11 that you are using work with Auto Focus?
Al
