1. 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.

2. EF-E (the one used for Canon EF lens) is Auto Focus, which can\'t be retained in the other models in this series.

3. 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.

4. With optical lens provided by our Japanese partner and a surprisingly attractive price, it is surely a smart choice to choose Viltrox f/Booster.
