Compact and lightweight "Pancake" type lens using glass-mold aspheric lenses at the 5th and 7th elements, effectively increasing the maximum aperture and reducing the overall thickness of the lens. The final element, positioned as closely to the sensor as possible, makes the incidence angle of light reaching the sensor smaller, and reduces vignetting and color shading, while helping to keep the lens's overall size small.
