摘要： A filter conversion device is employed in an optical system that is operative to locate one of a plurality of color filter units in an optical path frame member and is provided to support a plurality of filter units and is arranged so as to be movable in a predetermined plane between a light sending element and a light receiving element. Mechanisms for controlling the frame member to move horizontally and vertically in the plane are also provided. Thus, the desired filter unit is located in the optical path without requiring a large space for movement.

摘要： An interchangeable objective with a variable lens aperture for a camera has a stationary support member and a diaphragm-operating member rotatable about an axis between first and second annular positions relative to the stationary support member. A first elongated leaf spring is mounted on the stationary member to bear against the diaphragm-operating member along a first plane perpendicular to the axis. A second elongated leaf spring is mounted on the stationary member to bear against the diaphragm-operating member along a second plane perpendicular to the axis. The second plane is spaced from the first plane in the direction of the axis. A locking groove is formed in the diaphragm-operating member so as to alternatively receive the first and second leaf springs in locking engagement when the diaphragm-operating member is positioned at the first and second angular positions, respectively. An unlocking button is mounted in the diaphragm-operating member over the locking groove to push the respective first and second leaf springs out of engagement with the locking groove upon depression of the unlocking button.

摘要： A zoom lens for a camera having automatic diaphragm control has an element for adjusting the focal distance of the lens, a displaceable actuator, a diaphragm variable between a maximum aperture value and a minimum aperture value responsive to displacement of the actuator, and an element for displacing the actuator upon shutter release. An element maintains the diaphragm at the maximum aperture value during an initial portion of the displacement of the actuator. Another element changes such initial portion responsive to the adjusting element to compensate for changes in lens characteristics as the focal length is adjusted.
摘要翻译：用于具有自动光圈控制的相机的变焦透镜具有用于调节透镜的焦距，可移动致动器，响应于致动器的位移的最大光圈值和最小光圈值之间的可变光阑的元件，以及用于快门释放时使执行器移位。在致动器的位移的初始部分期间，元件将膜片保持在最大光圈值。另一个元件响应于调节元件改变这样的初始部分，以补偿焦距调整时透镜特性的变化。
