Generally speaking, I'm not one that likes zoom lenses; but when I considered what the Tamron 28-75mm f2. 8 Di III RXD is then I didn't mind it all that much. The talks about autofocus issues are in my opinion highly over exaggerated as I personally didn't see them with my unit.
In fact, I didn't suffer from any real autofocus issues at all. To that end, the Tamron 28-75mm f2. 8 Di III RXD focused better on the Sony a7r III than their lenses have focused on Canon DSLRs in my years of testing Tamron's newest lenses. These lenses have been emphasizing new philosophy within Tamron that gives each unit a silver ring around the mount, weather sealing, a new finish, and a number of major enhancements. While the world talks of Sigma this and Sigma that, I often like to remind folks that Tamron also isn't doing a bad job. . thephoblographer.com
