it went on sales in china this morning. i put an order in along with the filter adapter. hopefully i'll get an early serial number
btw if you are looking to use this lens on e mount, laowa is working on a tilt shift converter. you can buy this lens in SLR mount, and with laowa's tilt shift converter this thing will become a 17mm f4 tilt shift lens on e mount.
if you buy this lens in the native e mount, there will be no tilt shift solutions
