Did you autofocus with the 70-200 FE? Fast enough?
I have the fabulous Canon 70-200 F4 IS with the Metabones Samart iV adaptor. AF works but would be way to slow for shots like yours. Manual focus is very good but not for action shots.
Thanks Werner. to my amazement, had no problems with the AF. It was not planned to put the A7R in the sport. You'd better write in German. My English is terrible.
