Just to clarify: I've already decided to buy a 150-600mm and its primary duty will be landscapes and semi-stationary subjects. I had already read reviews about the a6000 and the Tamron tele and it is ok for my needs. Clearly: the faster AF the better, but it's not the primary feature for me.

 

The doubts were about which mount and adapter to use, and whether it made sense to wait for Tamron (or others) to come out with a native E-mount. The announcements of the Sigma adapter changed things because it makes it clear that Sigma isn't going to make native E-mount teles (see the discussion of the previous days). 

 

At this point the best solution looks like the Sigma + their adapter. Since they offer two 150-600mm I'd just like to understand whether the Sport version is worth while the extra cost and weight. 

Have you a link for the review of the A6000 and the Tamron? I would mind seeing it!
