35mm or 40mm voigtlander 1.4 nokton for A12 m mount?

Hi,

I have the multi-coated version, the first lens I bought for the mount module. My reasoning was that if I wanted a more vintage look I could pick up a vintage lens without the modern coatings. But I really like the lens so the single coated 35mm would be the first lens on my shopping list if I went full frame.

cheers
