Although it seems (just a feeling?) More fragile at fixing it with an original goal (I could not compare with the original but with that of my gun or 70-200 My tamron 17-50 or even the copy of my 50 f1.8), everything else is ok! It may protect as much as the original flare caused by sunlight but in case of violent shock I do not think much will protect the lens (sometimes it can save them!). That's why I did not give it 5 stars For the rest it's all good (and much cheaper: the shameful price of the original: about 1 / 10th the lens price already consequent)
