It is an awesome lens. I'll be interested in CO's response - I've considered the teleconverter, but so far haven't seen the need - my a7rii can go into APS-C mode, which gives me 600mm at 18 mp (vs 42 mp in FF mode); the 1.4x could take that up to 840 of course, but the lens is tack sharp so images that need it crop very well.
I'm sorry for the mix up. I thought that since the OP had just purchased the Sony that the Sony 100-400mm would be a great next lens. I've read a review about it and it's supposed to be a stellar lens.
