My experience with extenders is limited to shooting a forty five minute documentary for the TV Series Cosmos, being at the Grand Canyon and Meteor crater and being very far from talent, a couple hundred yards in some cases. I used the 70-200 2.8 II IS and the 2X extender. I shot a lot that week with just the 70-200 2.8 and fell in love with that lens. But with the extender, it fell apart, soft, lots of CA, no thanks. Kind of soured me on them.
