Of the supplier, I warn against other suppliers as Amazon which I ordered.
Mine has one or the other cosmetic manufacturing defect, which explains the difference in price between my monstrous sender (I-motion: 343) and Amazon (385).
These are just minor scratches (probably due to the fact that the goal was banged on something), but in short, I have a feeling that this price difference is explained by the fact that the Sender will provide in product with defects without use impacts.
Claws from transport: impossible given the way it was packed.
IN BRIEF, me it does not bother me for now anyway because it canon 70-300 is only temporary before buying a quality product L. But for those who want a new product in all cases, you are always assured of a fresh and genuine product from Canon.
