I just checked my 100-400 does not auto focus with the Canon 2X III
That's because with the 2x extender, the max aperture would be f11 so no autofocus...even if mounted on a 1D series camera.

May 20, 2014 22:08 | #3288 I can verify that my 1D-series bodies have AF capabilities with stacked Kenko TC's... It's not 'hummingbird' fast, but pretty damn quick... And still locks on target, even with outer AF points... Good light helps, but I was still able to lock on to surfers during overcast conditions... Hi. My name is Butch...

Gonna have to wait until I have a bit more reach to head back. Stuff

rezcar Goldmember More info | ^^ Corona Del Mar. I didn't get out of the office til after 6, so it was about 7 when I got here. I was telling Joe I'll probably never own a big prime (by choice) and my interest is landscape anyway. We should meet up, I know you shoot near here. This one was near dark when I shot it.
