We need to distinguish between two things: the product and the delivery:
1- The product: it’s in impeccable condition; the lenses don’t have a single scratch and everything works perfectly – the autofocus, the aperture, etc. The only sign of use is on the mount, likely from having been fitted and removed several times on another camera, but that’s to be expected
2- The delivery: a disaster. The parcel took just 24 hours to travel from Madrid to Alicante, which is brilliant. However, the journey from Alicante to Murcia (100 km) took two weeks; I had to make several complaints and contact customer support, both at Back Market and DHL. But it finally arrived.
