Description: * Viltrox f/Booster series can allow most of the lens to be used E-mount camera bodies mostly Sony's. Thanks to the built-in optical lens (4 elements / 4 groups), it can increase the aperture by one f/stop and extend the focal length. Allowing you to get in the larger area of light and achieve the depth of field that you prefer. * EF-E (the one used for Canon EF lens) is Auto Focus, which can't be retained in the other models in this series. * Viltrox f/Booster are quality made using precision-machined aluminium alloy with chromium plating on both of the camera body and the lens side of the booster to ensure smooth and endurable mounting, quality aesthetic. * With optical lens provided by our Japanese partner and a surprisingly attractive price, it is surely a smart choice to choose Viltrox f/Booster.
