I've been trying out a 1.4 X III Extender with my Canon 100-400mm (white) lens and EOS 700D body. I guess I already knew, but it's a bit disconcerting to find there's no autofocus. So I have to focus manually. I can't even get confirmation that the lens is focused through the usual red dots in the viewfinder. A couple of photos attached - the Reed Bunting is OK, the Pochard not so much.
Is it actually worth using the extender?
