Reparatur einer 1938er Canon

  • Habe mehrere alte Canon Kameras und diverse Nachbauten geerbt, teils mit Originalobjektiv. Die Blende scheint den Anschein zu erwecken, verharzen zu wollen. Kann ich sie reinigen? Wenn ja womit?:roll:

    Wie zerlege ich das Objektiv CANON LENS 50mm f:1,8 um an die Blende zu kommen?

    Gruß MamaMia

  • interessante Kamera, kann es sein, dass es dieses Modell von 1942 ist?

    Frühes rangefinder Modell, mit diesem silbernen Knopf an der Front..
