Wow Philippe, you have the ZM 1.4. I am jealous! I hear nothing but great things about that lens. I have the FE 35mm 1.4 which as you already know is a beast. I have been thinking of the ZM but the comments about vignetting have put me off a little especially since I would only use it on the A7 bodies. Do you have any thoughts on the matter? If you had a choice between the FE and ZM 1.4 which one would it be?
