This lens builds upon the best parts of the original and makes them even better while simultaneously reducing weight by 29%—making this lens the lightest in its class. Sony has also given this lens a brand-new AF system that promises up to four times the speed and has made plenty of optical optimizations that will appeal to video shooters, including improvements to focus breathing and focus shift.
