FIELD: optics. SUBSTANCE: fast lens has first component in the form of positive lens, second component in the form of negative meniscus whose convex surface faces image, as well as main positive meniscus whose convex surface faces image, and glued component incorporating convexo-convex lens. Third component in the form of additional positive meniscus whose concave surface faces image is introduced between negative and main positive meniscuses; fifth component in the form of convexo-convex lens is introduced between fourth component and glued one; sixth glued component is assembled of concavo-concave and convexo-convex lenses; focal lengths of components are interrelated by formulas given in description of invention. EFFECT: enhanced image quality throughout entire field of vision due to improved correction of field aberrations. 1 cl, 2 dwg
