I have been following some of this thread with interest as I have just bought an A7r. I have a Fotodiox adapter onto which I have hung my ZE35 f1.4. It is no longer a light camera! So I was just about to order a Loxia 35mm when I saw this thread and now would like to ask which lens to go for Loxia, ZM or the forthcoming Zony 35mmf1.4? I love the ZE rendering and the f1.4 if that helps the advice.
