Colis toujours pas reçu !

Bonjour. Je ne peux pas donner d'avis sur ce produit car votre envoi ne m'a toujours pas été livré ! Comment puis-je savoir où en est le transport du colis ?


This thing is garbage. I can't even tell if I was able to update the firmware as no firmware is even showing in the window. I tried downloading the firmware, as soon as the file copied into the EF-EOSM2 drive, I heard a beep and the window closed and I checked the drive and there's nothing in there except System Volume Information and in that folder there's WPSettings.dat but, there's no apparent firmware installed anywhere. Further, the garbage won't even autofocus correctly. I wouldn't recommend this product.

Very good

The autofocus is a bit affected, sometimes it doesn't work at all, but, overall, it is great, specially about its optics.

The converter can auto focus with Canon EF lenses from 60mm onwards. A good option for 2x teleconversion.
