摘要： A lens-interchangeable camera includes a focus detector performing focus detection and a controller performing a drive control of a lens based on a defocus amount. The controller finishes focusing operation without driving the lens when the defocus amount is out a range of a first in-focus determination width, and performs the focusing operation when the defocus amount is out a range of the first in-focus determination width. The controller finishes the focusing operation without performing the focus detection again after completing the drive when the defocus amount is out a range of a second in-focus determination width, and performs the focus detection again after completing the drive when the defocus amount is out a range of the second in-focus determination width. The second in-focus determination width is set to be greater than the first in-focus determination width and be greater than or equal to a drive limit value.

摘要： A focus setting system for a camera in which a photographer can observe a focused subject image in a viewfinder and which corrects the focus prior to exposure such that a photographed picture is in focus. Specifically, the focusing system corrects for errors introduced by varying apertures. The focusing system has a photographic lens which has a memory for storing focus error data which represents focusing adjustment values from an open aperture to a number of predetermined apertures. A focus detection device detects a focused state of the photographic lens using a portion of the incident light rays of the photographic lens. A first drive unit drives the photographic lens by calculating a focus drive amount which achieves focus at open aperture. The focus drive amount is calculated from the focus error data and the focus state detected by the focus detection device. A second drive unit drives the photographic lens by calculating a second focus drive amount which sets the focus for a predetermined aperture based on the focus error data and the focused state detected by the focus detection device.
