A mounting for an objective or projection-type lens has a male bayonet with beveled lugs engageable with a recess in a female bayonet plate and a one-piece spring is attached to the female plate and applies clamping force against the lugs of the male bayonet and also against the recessed shoulders of the female plate to provide for rapid changing of the lens and to maintain the lens in precise focal position.
