I was very disappointed with this product. The title does not correspond to the product, in fact they advertise a canon lens (difficult to find at these prices), whereas it is a tamron lens compatible with a canon body.
After contacting the retailer, he accused us of being at fault, and of having looked at the product photo incorrectly, although on the invoice it did say "canon EF-S17...". As we didn't have the latter product, no exchange was possible.
Fortunately the Back Market team supported us so that we could get a full refund.
This mishap happened on 22 December, leaving a young girl without a present under the tree.
