The relationship of super short-focus panoramic fish-eye lens’ focus and resolution was studied comprehensively. It is proved that the shorter the focus, the higher the resolution of scenic circle area. A panoramic fish-eye lens is presented, whose ratio of focus and image height is less than 0.35, horizontal field is up to 360° and vertical field is more than 180°. The results show that the spatial pixel of scenic circle area with half vertical field 45-90 degree is up to 75%, and the modulation transformation function is greater than 0.4 at the spatial frequency of 200 lp/mm. Its imaging quality is very well, its resolution of stretching the scenic circle is very high, and it works for panoramic monitor and high definition.
