Claim 4

A lens system as defined in claim 1, wherein the forward one of said three components of said first diverging group (NN) comprises at least two negative lens elements separated by an air space shaped to provide an air lens of diverging action, through which light rays entering the front of the lens system must pass before entering the next succeeding one of said three components of said diverging group (NN).
