The 35mm Loxia (Image courtesy: Stockografie).
Stockografie (Click here) tested both Zeiss Loxia lenses:
The Zeiss Loxia 2/35 as well as the Zeiss Loxia 2/50 is a wonderfully crafted lenses. They are built to withstand almost anything a photographer could run into. I would not hesitate to use these lenses under harsh conditions such as rain, dust or any other kind of influences.
If I would have to choose between one of the two I would go for the Zeiss Loxia 2/35 but that is only my personal preference as I like the 35mm field of view better than that of the Zeiss Loxia 2/50. In terms of image quality both lenses are amongst the best you can get for your A7 series camera with a native E-Mount.
