Im still umming and ahing over the Batis 40, yes it has issues with the aperture when close focusing, and AF isn't great in the dark at close distances but I like the focal length, and I love Batis colours. I have seen so many people online slate the AF of the a7r2 as slow and unreliable, but to me, Ive never had a problem with it. However I have never used any camera above the a7r2, I bet if I bought the a7r3, I would get out my pitchfork and join the online crowd
Im also tempted by the Batis 85 or 135, it was the 85 until I saw the thread for the 135 over on FM forums, there are some lovely images in there.
Just for fun - here is Kai with his a7r2 review

It just goes to show how quickly we forget or move onto better things like the a7r3....
