Zeiss C Sonnar 1.5/50
It is the modern version of the classic 1.5/50 Sonnar.
A couple of examples of photos with evident bokeh:
Sonnar type lenses in 50mm focal lenght are quite uncommon compared to double Gauss (Planar) lenses and 4-elements (Tessar) lenses. |
Is this the same as the one for Nikon S/Contax mount? I happened to read about that one last night, different design to the classic 1.5/50 Sonnar, do you find the rendering to be significantly different to the old version?

Sonnar C T* 1.5/50
The two designs differ in that the triplet formed by the second group in the original is now two air spaced elements. The middle element of the triplet in the original is there as 'filler' to reduce the air-glass interfaces and improve contrast. Modern glass types mean it isn't needed, hence the design change. Just wondered how the rendering was effected by this change.
