### ⭐⭐⭐⭐⭐ Review
*by L***N on 20 July 2019*

Hallo Habe meinem Mann diesen Adapter geschenkt. Er braucht ihn, um an seiner Lumix G81 die vorhandenen Objektive mit Canon EF/EFs anzuschließen. Die Lumix wird größtenteils für das Focusbracketing/Stacking mit dem Elektronischen Verschluss und dem Canon Macro-Objektiv verwendet. Die Firmware des Adapters wurde zuerst auf die Version 3.3 von der Viltrox Website aktualisiert. Die Firmware der Lumix G81 ist die 1.4. Im Kamera-Menü wird nach adaptieren der Objektive die Firmware der Kamera UND des Adapters angezeigt !! Als Test wurden trotzdem folgende Objektive mit dem Viltrox - Adapter an die Lumix G81 adaptiert : Canon EFs 60mm Macro Canon EF 70-200mm L 4/IS Canon EF 50mm IS/STM Canon 16-35 L 4/IS Tamron 90mm 2,8/ IS VCC F004 Tamron 24-70mm 2,8/VC A007 Irix 11mm 4 alle Objektive haben an der Lumix G81 funktioniert. Das IRIX 11mm natürlich nur mit manuellem Focus. Bei allen Objektiven springt der Kamarainterne Bildstabilisator an und funktioniert !! Besonders begeistert ist mein Mann, dass das Tamron 90mm funktioniert !! Der Adapter erfüllt also voll und ganz unsere Erwartungen. Die Verarbeitung ist einwandfrei, da klappert nichts und die spielfreie Objektiv-Adapter Kombi sitzt spielfrei an der Kamera. Ich habe 95 Euro bezahlt, woanders könnte ich fast das doppelte für einen anderen Adapter ausgeben, ob der in Funktion oder Verarbeitung besser ist, weiss ich nicht. Ein Vergleich im Netz wäre ganz interessant. Eine Bedienungsanleitung in Deutsch mit Erklärung des Firmware updates wäre schön. Wir können bei unserem Test natürlich nur von der eigenen Kombi ausgehen und nicht auf Gehäuse und Objektive anderer Nutzer zurückgreifen.
