Tamron is working on a 28-75mm F2.8 lens for full-frame Sony mirrorless cameras: Digital Photography Review
Details are thin at this point, but the 28-75mm F2.8 Di III RXD will offer "superb optical performance" and a moisture-resistant construction.

Tamron 28-75mm f/2.8 Di III RXD - UK Exclusive Review - Amateur Photographer
Superb optical performance, including both outstanding image quality and beautiful background blur effects (bokeh), provided by fast F/2.8 aperture. Comfortably light weight (19.4 oz.) and compact (4.6 in). Close-focusing; Minimum Object Distance: 7.5 in at wide-angle setting and 15.3 in at the telephoto position. All-new RXD stepping motor AF unit is extremely quiet and therefore perfect for video capture.
