Passt leider nicht an das Leica APO Televid 77
Ich habe mir den Ring bestellt, weil in den Fragen und Antworten zum Hyperion MK 4 Zoom dieser für den Anschluß des Okulars an die alten Leica Televid 77 Spektive empfohlen wurde. Leider ist das eine falsche Annnahme. Zumindest mein Televid 77 hat ein M41 Anschlußgewinde (Steigung wahrscheinlich 1 ?). Zudem habe ich das Hyperion MK 4 provisorisch an das Spektiv adaptiert und leider feststellen müssen, dass man nur bei der längsten Brennweite 24mm damit in den Fokus kommt. Ob das bei den neueren Televids anders ist, kann ich leider nicht sagen.
  • Sauber und präzise verarbeitet
  • nichts außer dass es bei mir nicht gepasst hat
