摘要： A camera with a non-TTL type finder may avoid a mechanical complexity, may be produced with a gentler standard in dimensional accuracy than conventional cameras of such a type, and may lower consumption of a power battery.A finder focusing dial is manually rotated together with a cam member to swing an interlocking lever. An end of the interlocking lever moves an objective lens frame back and forth. When it is observed that an image of a target subject becomes focused on a finder focusing screen through a finder eye piece, the rotation of the dial is stopped. A focused state detecting device detects a stop position of an objective lens to supply a detection value to a photo-taking optical system focusing amount determining device to determine an amount of focusing. A drive device drives the photo-taking optical system into an in-focus state in accordance with the focusing amount thus determined.

摘要： A method of forming a microstructure array suitable for use in the production of a focusing screen used in a finder system of a camera. The focusing screen includes an optical material in plate form having on one surface of a plurality small lens portions that project in a regular array of equilateral triangles from the optical material and each of the which has concentric contour lines, with a central apex. A flat portion is formed between adjacent small lens portions and a constricted portion is formed in the middle portion of the inclined surface of each small lens portion, with an irregular pattern of finer asperities is formed on the surfaces of the small lens portions and the flat portion. The high and low spots can be reversed. The method of forming a microstructure array includes the steps of forming a fine pattern of elements on a layer of light-sensitive material capable of transforming a distribution of light intensity to a surface relief by exposing the layer through a microlens array to rays of light with an intensity distribution corresponding to individual elements of the fine pattern. The microlens array may be replaced with a group of pinholes.

摘要： A focusing screen for observing an image formed by an objective lens is constructed of a liquid crystal layer, having a dynamic scattering effect, sandwiched between a pair of parallel transparent electrodes. At least one of the transparent electrodes is divided into a plurality of discrete parts. The discrete electrode parts are connected as independent groups through a switch mechanism to a driving circuit. The switch mechanism permits one or more of the groups to act as different elements in response to an applied voltage, depending on the F value of the lens. Accordingly, the scattering degree of the focusing screen varies as a function of the F value and not the applied voltage.
