The Zeiss 35mm f/2 ZF produces a slight degree (~0.7%) of barrel distortion.
This is about in-line to what we´ve seen from other manufacturers.
The chart above has a real-world size of about 120x80cm.
The Zeiss lens exhibited a relatively pronounced vignetting of 0.74EV at wide-open
aperture. From f/2.8 onwards the problem is negligible under field conditions.
This is a quite typical behavior for a lens in this class.
Similar to the other tested Zeiss lenses the Distagon 35mm f/2 produces breathtakingly
high center resolution figures straight from the max. aperture setting. At f/2.8 and
f/4 the center quality matches or exceeds the limits of the 10mp D200
sensor. In contrary the border performance is "only" very good at large aperture
settings but increases steadily towards medium apertures where the quality reaches
Below is a simplified summary of the formal findings. The chart shows line widths
per picture height (LW/PH) which can be taken as a measure for sharpness.

Chromatic Aberrations (CAs)
Chromatic aberrations (color shadows at harsh contrast transitions) are very low
at large aperture setting but are getting stronger towards medium apertures.
In absolute terms the average CA width @ f/8 is still moderate with 1.1px at the
