Once something like an Alpha 7rII arrives I would jump on the FE-mount train. But I have some consideration and one of them is that I like manual focusing (using magnified live view). I have nothing against AF, just that I want to be able to focus manually, too.
The lens I would be most interested in is a short large aperture lens with excellent correction. Yes, the Otus 85/1.4 would fill the bill, but I don't appreciate the size of neither the lens nor the bill. The longer Zeiss 135/2 Apo-Sonnar would also fill the bill, but it is a bit to long for my perceived needs.
The new Batis 85/1.8 is very interesting and so is the 90 mm macro, which seems to be quite excellent. But, these later lenses are focused by wire. How workable is that?
I don't need very large aperture, but I want a lens that is fully useful fully open, without magenta/green fringing in out of focus areas.
