B&H has the Mitakon Zhongyi Speedmaster 35mm f/0.95 Mark II lens for $419 (reg. $599) as its Deal Zone deal for today only. Check it out here at B&H Photo.
I tested the first version of this lens a few years ago and loved it. It was a little big and heavy for the Sony A6000 but this is the Mark II version of the lens and it is both smaller and lighter than its predecessor.
