14-30 f4S and the Z-Mount

[chambeshi]

"Thanks to the larger rear element and short distance to the sensor, the front element of Nikon's new 14-30mm Z-mount lens is surprisingly small and remarkably flat for such a wide-angle optic. A side benefit is that you can actually use front-element filters with it, something that's not possible with DSLR lenses of similar focal length and aperture."

and interesting to read the implications for improved AF with the 70-200 f2.8S
