Iis there a location I can fine the compatibility listing with auto focus for the 1.4 and 2X extenders?

Seems to be a decent list here, but I can't vouch for its reliability.

Hi hpatt!

Take a look at the "Notes" section under "Specifications" for each of the extenders on our site. It lists the only lenses that are compatible with the extenders. Also, if you look at the manual for the extenders, it will detail every lens and whether or not auto focus will work with the extender.
