An information handling system camera provides a 117 degree field of view with low distortion by capturing visual images through a lens having eight lens elements. The first lens element closest to the object, the third lens element and the sixth lens element each have a glass material, the remaining lens elements have a plastic material. The first two lens elements and the last lens element each have a negative refractive power and the remaining lens elements have a positive refractive power. Lens elements two and four through eight each have aspherical surfaces.
