Zeiss 40MM Sonnar ?

I doubt it, at least not on center.

Actually at f2.8 the Nokton is noticeably sharper across the entire field. Thats not to say the Zeiss is not a good lens, its great but at f2.8 the Nokton is closed down 2 stops, 2.8 to 5.6 its at its peak. At 2.8 the Zeiss is good but thats not its best aperture.
