Ultron: Winter bokeh
Voigtländer Prominent Ultron 50mm f2. It is said to be the sharpest fifty of its time.
Optic design differs from latter version by having only six elements in five groups. Its design is probably an evolution of Xenon (specifically Kleinbild version) design.
To me it looks gentler than other Ultrons. It is slightly over corrected so balls of confusion had less sharp edges in most situations. In general it gives more controlled bokeh than variants.
