As tested on the Nikon D3X the Samyang has a much higher score than the other two according to DXO mainly due to higher resolution and uniformity over the whole image field. Yet, looking at the use case scores - the star ratings - the Zeiss 35mm/1.4 has a higher rating for landscape than the other two lenses. It doesn't make sense to me.
