not perfect.
x-axis: distance from optical
axis in °, y-axis: resolution in arc minutes

The apparent field of view is approx. 47°.
Contrast:
Very good contrast because of good multicoating and use of just four
lenses.

Noticeable, but not troublesome cushion distortion.

Good, but eye relief is a little bit short. Better to fold the rubber
eye cup to view the complete apparent field.

Recommendable.
