You probably guessed it by now That I got this to be able to use nearly a glass mount, it works it is reasonably fast and offers some of the nice new features: such as face tracking cameras like the A7 offer on a glass mount.
Sadly you only get those things in the very center of the frame where the AF points are located.
That is OK if you have a wide DOF and are able to focus and recompose with a shallow DOF you can not do that.
