You failed to mention that the 135mm focal length is not a lens but a digital zoom option added in the portrait mode alongside the other focal lenghts already present on the X100 Ultra.

Vivo is gearing up for the launch of its flagship X200 series phones, finally taking the wraps off the official photos/renders as well as detailed specs of these expensive Android-powered products. Improvements over the previous generation are plentiful including but not limited to the cameras, processor and battery life.
