Funleader announced a new and updated version of their Funleader 18mm f/8 cap lens for Nikon Z-mount (see previous version here). The price is $199 and orders can be placed directly at the official Funleader website with international shipping. Additional information, including specifications and MTF chart can be found here.
Update: I am not 100% sure, but it seems that the new lens is for Leica M-mount only and you can get an adapter for Nikon Z-mount for an extra $29.Waiting on a confirmation from Funleader.
