The SIRUI FE is a fisheye attachment lens for exceptional perspectives.
With its image angle of 170°, it creates the typical fisheye look. As a full-frame fisheye, it takes full advantage of the smartphone sensor and there are no unwanted vignetting in the image. Since it doesn't have a focal length, it sharply reproduces from infinity to the close-up range (0.5cm).
The lens is screwed into the supplied smartphone clip and then plugged into the cellphone.
