Thanks for the replies,and info, my camera is a Canon 6D mkii, with a Tamron 110-400mm f/4.5 lens, since the Canon teleconverters may not be compatible with other brands, I'll try a Tamron teleconverter that I found online for a great price.
Hopefully I'll have some images to post in a couple of weeks.
Thanks,

@400mm your lens is f/6.3.
The 6D MK II will not autofocus with the 2x teleconverter.
The (Model TC-X14) will autofocus with your lens and camera @ f/8 according to the Tamron Compatibility list.
@ f/8 the 6D MKII will only center point autofocus.
