For the price there is absolutely nothing to say the fish eyes he is terrible surprising distorted photographs, I used me for American cars, distorted corners of buildings and Selfy of crazy! well on the optical drives on the edges blur, but that's part of the style of the photo! know that this is all aluminum and real glass lens! I had not understood but the two sides are not one for the camera and the other to the goal, but it is reversible or Zoom / Macro or Fish Eyes not 2 at the same time each on its sensor, no. Finally it is very small, the merchant gives a bag with a lace to put it in the pocket and remains dust that's the most fun and super functional. super well packaged and delivered quickly. for the price everything is more than perfect!
