摘要： In an automatic focusing apparatus, wherein first zone representing an in-focus condition and a second zone for sufficiently assuring detection precision of the automatic focusing apparatus are provided for the position of a focusing lens, the focusing lens is driven on the basis of a defocus amount when the defocus amount falls within the range between the first and second zones, and thereafter an in-focus signal is output upon driving of the focusing lens, thereby shortening a delay time from the end of driving of the photographing lens to generation of the in-focus signal.

摘要： A zoom lens has, in succession from the object side, a first lens group of positive refractive power, a second lens group of negative refractive power, a third lens group of positive refractive power and a fourth lens group of positive refractive power. The first lens group, the third lens group and the fourth lens group are movable toward the object side for a magnification change from the wide angle end to the telephoto end. The focusing up to a short distance object is made possible by moving the second lens group along the optic axis from the position of its telephoto end toward the object side and moving the third lens group along the optic axis from the position of its telephoto end. The zoom lens satisfies the following condition:-0.5

摘要： A fast telephoto lens has a longer focal length of 300 to 400 mm, and an F-number of about 2.0 to 2.8, which does not utilize a floating mechanism, has a small deviation in aberration when the lens is focused on an object, and has a simple construction for shifting only one lens group. The fast telephoto lens is of internal focusing type and comprises positive, negative and positive lens groups from the object side, and only the negative (second) lens group is shifted to obtain an in-focus state.
