    摘要： In a zoom camera having a zoom lens including a variator lens, and a driving system for driving the variator lens, the image magnification is computed in accordance with a predetermined program based on the detected object distance, and such a focal length is computed as to obtain a specified value of image magnification based on the detected object distance and the computed image magnification, and the obtained focal length data is fed to the driving system. As a result, auto-zooming with a suitable image magnification in accordance with the object distance can be achieved.

    摘要： A focus detecting device capable of correcting an error, between an in-focus position of a photographic lens detected by a focus detecting means and an image field position affording the best image. Focus detection is made using plural focus detecting areas provided on and off the optical axis of the photographic lens, to obtain an in-focus position. Then, the thus-obtained in-focus position of the photographic lens is corrected using an appropriate correction value out of those preset and stored in a ROM in the lens according to whether the focus detecting area used in the focus detection is an axial or off-axial area, or according to the focal length of the photographic lens as well as the photographing mode. And the photographic lens is thereby set to the best image field position.

    摘要： An interchangeable lens unit is detachably attachable to a camera main body through an improved bayonet arrangement which includes three sets of corresponding bayonet claws, one of the corresponding bayonet claws of each set being provided on a mount member of the lens unit and the other on a mount member of the camera main body. The bayonet claws of the three sets are formed, in mutual dimension and dispositions thereof, such that the corresponding bayonet claws of one of the sets engage one another at an upper peripheral part of the mount members immediately above the center of the mount members and the corresponding bayonet claws of the remaining two sets engage one another respectively at lateral side peripheral parts of the mount members diametrically opposite to one another with respect to the center of the mount members in the lateral direction, when the camera main body and the lens unit attached thereto are viewed from their front with the camera main body held in a normal erect state. The camera main body is provided with a spring member which can urge the bayonet claws on the mount member of the lens unit for ensuring contact between the mating mount surfaces of the mount members.
