36MP Sony A7R
Zeiss Loxia 50mm f/2 Planar

This scene is at close range, thus throwing the background strongly out of focus. It shows the bokeh style from f/2 to f/11. Assessing sharpness is a non-goal here, since the leaves were not still. Zeiss implies pleasing bokeh with the Loxia lenses :

Almost circular aperture with 9 blades, for especially harmonious rendition of highlights outside of the focal plane.

This example supports the above claim. Indeed, it is the main reason to consider the Planar versus the Sony/Zeiss 55mm f/1.8 Sonnar: lenses each draw differently, and a particular drawing style may be well suited to some purposes more than others. The Planar is a classic and much-imitated design for its even-tempered behavior.
