It is "an optimized" Tamron SP 24-70mm f/2.8 DI VC USD Lens except no VC and Pentax coatings. It is a well regarded lens, optically (ironically an old, respected Pentax lens designer that Hoya dismissed is one of it's designers). It is Tamron driven (ultrasonic). According to Asahi Man the old Pentax SDM micromotor is completely out of use.
