We were able to try out Sony's '4D' continuous
AF with this lens on an A7 II, and it was, frankly,
jaw-dropping impressive. As long as our subject
stayed within the phase-detect area of the frame,
horizontal, vertical, and depth tracking was
incredibly accurate, fast, and completely silent for
an erratically moving subject. Almost every shot
was tack sharp on the intended subject matter at
F1.4. In good light, we'd wouldn't be surprised
if this combo gave top-of-the-line DSLRs a run for
their money when it comes to continuous AF.
