Any guesses on what the RXD stands for?

The only problem with the original Tamron 28-75 f2.8 (I've got two!) is the slow focusing so I'm guessing it's a new, not-USM focusing thingy.

Or it could just be a lens coating :-)

Most likely D as in AF Drive. What the RX part means is anybody's guess.

Edit: it’s a video-friendly stepper motor drive. Not surprising.

FYI: Sony is not the only FF mirrorless manufacturer...
