The Viltrox 35mm f/1.2 LAB should also be available for Z-mount in the foreseeable future.
The E-mount version that has already been released is receiving excellent reviews.
The fact that the reviewer, in this case Dustin Abott, would still prefer the Viltrox 35/1.2 LAB to the Sony 35/1.4 GM even if the latter were priced identically to the Viltrox, i.e., significantly cheaper, shows how good this lens is for the price.
But not only optically, but also in terms of AF speed/motors.
