What can you say about the Amazon delivery yet? Just perfect! Quick and free of charge. The lens is certainly worth the money, who wants more must also (significantly) pay more. The build quality is OK so far, the visual qualities in the kit lenses, but it is much cheaper in price. Very good is the luminous intensity, can be fully extended without flash rather make good interior shots, at least with the Sony Alpha 550th Have this lens the way more expensive seen in various camera stores even as "offer". My Conclusion: Buy at the price there is nothing comparable and Amazon has plus the lowest price.
