## Customer Reviews

### ⭐⭐⭐⭐⭐ Nice TC
*by  on Reviewed in the United States December 26, 2021*

It works very well in the Sigma 500mm f4, the focusing speed is reduced a bit, but there is almost no loss of image quality.

### ⭐⭐ Qualitativer Downgrade
*by  on Reviewed in Germany October 13, 2020*

Mein Bedarf an einer größeren Brennweite für Astrophotographie hat mich dazu getrieben den Adapter zu kaufen, hier kann ich nur davon abraten. Ich benutze diesen hauptsächlich für mein 600mm Cont. und die Bildqualität des sonst großartigen Objektiv ist dahin. Da kann man gleich das Bild digital vergrößern, kommt auf das Gleiche raus, ist also das Geld nicht wert ...

Livraison parfaite le jour promis, sauf que l'article principal ne correspond pas à l'article commandé.Dans les caractéristiques du produit, il est bien précisé, comme indiqué sur la photo 1, que ce modèle TC1401 est bien pour une monture EF Canon et il est bien donné comme compatible avec le Canon 5d mark3.La référence de l'article livré est celle pour une monture Sigma "S.A" et non pour une monture EF Canon come indiquépar erreur dans les caractéristiques.Demande de renvoi de produit en cours pour échange avec le bon produit.Le commentaire sera modifié dès que le problème aura été solutionné.
