- typische historische Kamera
Zum Auffrischen und Erinnern . . . .
. . . sind diese Seiten hier gedacht, denn viele wissen nicht mehr oder noch nicht, wie es damals angefangen hat und wie das wirklich funktioniert mit dem Fernsehen, den Kameras, den Videorecordern, den Tonband- und den Magnetband- geräten aus alter Zeit. Viele Bilder können Sie durch Anklicken vergrößern.
Das Bild auf dem Kamera-Color-Bildsucher KC 17 war super.
Es war 1988 die letze Krönung auf einer KCM 125, der Sucher in Farbe. Die 7" Trinitron Röhre ermöglichte endlich eine extrem scharfe und besonders helle Darstellung des Sucherbildes.
