I have not used it, but the new Zeiss Milvus 35/1.4---a new design not related to the ZF 35/1.4--- is well-regarded by certain lens-savvy commentators (Lloyd Chambers and AnotherMike at DP Review), but light and compact it is not. Also no AF.
Looks good but at 1.1Kg not very suitable for a small mirrorless camera, at least not for me.
The S-Line 35/1.8 is out of consideration?
It is the obvious choice currently but on the slow side and Nikon already announced that besides the 50/1.8S there will also be a 50/1.2S, I think and hope they will extend this approach to the other primes as well and come up with a 35/1.2S in 2020 or so and that will be the lens I want for sure (to complete my f/1.2 trio once more).
So the 35/1.8S will be a placeholder for me and as I only go out and shoot a few times a year I'm done with the huge depreciation of lenses I already know I will sell. That said is does look like to be a very nice and capable lens so it IS hard to ignore.
