TS Super Ploessl 12mm
Very good over the complete field of view, just very close to the edges not perfect.
x-axis: distance from optical axis in °, y-axis: resolution in arc minutes
Apparent Field of View:
The apparent field of view is approx. 47°.
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.
Nice. You do not need more to use it for a long time.
