The reviews are rolling in for the Tamron 28-75mm f/2.8 Di III RXD and most reviewers are calling it the best mid-range standard-zoom for E-Mount at this time. It easily bests the Sony Zeiss 24-70mm f/4, while coming close to matching the Sony G-master 24-70 f/2.8 at a fraction of the price. Of course, some might need a 24mm wide over a 28mm wide, but if that isn’t a factor than the Tamron is probably the lens for you.
