The new Zeiss Batis has been enthusiastically reviewed by Lloyd Chambers, Imaging-Resource, Photography Blog, and a number of other sites none of which have tested eye-AF.
There's an extensive discussion on problems with eye-AF on Fred Miranda by folks in Europe who have actually received and used the lens. It seems, from the posts, that for some reason, eye-AF is inaccurate, with consistent front focusing. It is scheduled to start shipping in the US in 5 days. I have one on order from my local dealer. Since eye-AF is important to me, I plan to immediately test my copy as soon as I receive it and if the stories are true, it will be returned and it's back to the drawing board unless Zeiss/Sony can figure out a solution.
