TS Super Ploessl 25mm
Very good over the complete field of view, just close to the edges a little bit worse.
x-axis: distance from optical axis in °, y-axis: resolution in arc minutes
Apparent Field of View:
The apparent field of view is approx. 42°.
Very good contrast because of good multicoating and use of just four lenses.
Slight cushion distortion. Very slight colored fringes near to the edge.
Nice. You do not need more to use it for a long time.
