Returned item, not for lens performance! I loved having it in hand! but I'll order it with another provider. Explanation: (hstmall provider) for a new article submitted to a guarantee, I expect to receive it in a cardboard manufacturer (in this case SONY) or he was in a very ordinary cardboard where the brand SONY there was almost absent so impossible to declare the item for warranty service. Moreover doubt rises about the new appearance of the product, especially when a part is missing (the visor) and the lens is a little dirty. I had the impression of having received a second hand item to the price of new ..
As for the technical aspects of the objective, the little that I had it in hand, it fits perfectly on a hybrid SONY NEX 5T it is the same size as the unit it is completely manual, so optical zoom only the development can be automatic based on camera settings it comes with a front cover plus a rear cover and a visor logically.
