Quick Test: Rodenstock Ysaron 30mm f/3.5 Lens

Rodenstock Ysaron 30mm f/3.5 and enlarger lens for scale.

Rodenstock Ysaron 3,5 f=30
Mounting threads: none
Filter threads: none
10mm length
16mm outer diameter
Note: This is the smooth barrel type, there is also a full threaded body type.

The wide focal length and fast aperture make the Ysaron 30mm lens attractive, that is on paper at least. For a quick image quality test at 3x I stacked the Ysaron on a Mejiro 90mm line scan lens and it returned sharpness and CA correction that is below average for an industrial lens of this type.
