This scene is at infinity focus, which is a demanding situation for any lens. It was taken at nearly the same time and from the same position as the Loxia 50mm f/2 series, thus providing an excellent perspective for the 50/2 Planar vs the 35/2 Biogon.
A distant landscape scene like this is revealing of any lens shortcomings, particular in the mid zones and edge/corner areas. Indeed it is one of the most difficult challenges for any lens. This scene in particular has an excellent near-to-far layout which is brutally revealing of any shortcomings.
The MTF chart for the Loxia 35/2 Biogon suggests disappointing contrast (haziness) at f/2 throughout the frame, which is surely unexciting for any usage except where one desires that very low contrast (e.g., for a soft-look portrait). The MTF chart also suggest that central sharpness and contrast will be superb by f/4 at the latest, but that mid zones and edges and corners might have some difficulty even well stopped down. Moreover, there may be some field curvature in those areas.
