Frage von Sceetch:
Good day,
would like to see a baun adapter.
Time, a fundamental question:
The Picture on the glass so plan to 180 ° rotated displayed. I would like using a lens again correctly reflected. Document in the whole mess but not smart. Linsenart What do I need it? Convex, Concave, Bokonvex, Bikonkav ...?
Thank you very much.
Antwort von Markus:
To take a picture upside down (or in this case again the right way) to rotate, it would basically just a convex or Bikonvexlinse Required:
zum Bild Through the use of such, there may be differences in the focal lengths of the individual colors, resulting in chromatic aberration expressed:
zum Bild In this case, would need corrective lenses, as in any good optics.
Antwort von Sceetch:
With a Konvexlinse would be a reversal is only possible if the 1.Mattscheibenbild to a second screen would be projected, which would then abzufilmen (ie unthinkable). Aerial photos can not be dealt with as you get the idea.
Otherwise it only s.Umkehrspiegel + b) additional reverse pentaprism as with SLRs, which is a double reflection is reached (vertical and horizontal) and no rotation of 180 degrees, but in the end comes out the same.
