They especially they made the diameter of the lens smaller and there is no free lunch.
The 18 to 50 mm is a very compact f/2.8 zoom with a minimalist design.
The size is nearly identical to a standard 24 to 70 full-frame f2.8 lens but instead of that 24 to 70 you are getting a 25.5 to 60 mm equivalent at 1.8.
