Christopher Frost reviewed the Sony E-mount Kamlan 50mm f/1.1. This APS-C manual focusing lens is on sale for $169 on Amazon US, Amazon DE, Amazon UK, Amazon FR, Amazon IT and Amazon ES.
There is also a short test from Biogon on Reddit.
UPDATE: SAR readers (Thanks!) also spotted the Kamlan 8mm F/3.0 fisheye lens on Amazon.
