Abstract
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.
