Order: Zeiss Loxia 35mm f/2 Biogon. Loxia lenses shipping soon here in USA.
The Loxia are very well built lenses with excellent feel and real manual focusing. Highly recommended.
Examples with the Zeiss Loxia 35mm f/2 Biogon on the Sony A7R:
With HD and UltraHD images and many large crops.
UPDATE: added another image in black and white and color versions (“Last light on Cathedral Peak”), a very nice demonstration of just how good the Loxia 35/2 Biogon can be for landscape shooting.
