It's been awhile since any of the major third party manufacturers said they'd be developing any sort of lenses for the Sony FE lineup of cameras, but the new Tamron 28-75mm f2.8 Di III RXD is being announced right before WPPI 2018. Though details are still scant, we know a few major tidbits. Today's press release states that the lens will have a minimum focusing distance of 7.5 inches, measure only 4.6 inches in length, and have what Tamron is calling their Rapid eXtra-silent stepping drive–which is essentially a silent, really fast focusing motor. Plus, it's going to have moisture-resistance and a coating on the glass elements that makes it resistant to fingerprints.
