摘要： A varifocal objective has an axially shiftable positive front component, an axially shiftable negative intermediate component, and a fixed positive rear component or basic lens group. The latter component consists of five closely spaced lens members, all but the second of them singlets and all but the third of them positively refracting. The intermediate component is separated from the rear component by a diaphragm space which in a position of close approach of these components, corresponding to maximum focal length, is still substantially greater than any air space between the lens members of the rear component. With a varifocal ratio close to 3:1, the distance between the front and rear components is the same in the positions of maximum and minimum focal lengths.

摘要： A multiple purpose optical device that may be selectively and removably attached to engageable means on either the forward portion of a camera housing containing shutter means and a light sensitive film or engageable means on the forward portion of a projector containing a light source and a holder for said film after the film has been exposed and developed. The device when mounted on a camera as above described laterally compresses the light image to which the film is exposed and increases the field of said camera as a result thereof. The device when mounted on said projector laterally expands the developed image on the film as said developed image is reproduced, with the compression and expansion being to such a degree as to nullify one another and provide a non-distorted and natural reproduction of said developed image on a projection receiving surface.

摘要： A zoom lens for cameras is provided which comprises four groups. The third group consists of a biconcave lens both surfaces of which have the same radius of curvature, and the fourth group consists of a biconvex lens both surfaces of which have the same radius of curvature. In combination of these third and fourth groups with the first and second groups, the spherical aberration as well as astigmatism of the lens system may be limited within a very small range and a flat image is obtained.
