Described is an image capturing apparatus, which makes it possible to accurately secure the distance between the two lens groups, even if the interval distance between the two lens groups varies from the default design-distance value. The image capturing apparatus includes a first lens group, a second lens group, a first driving section to drive the first lens group, a second driving section to drive the second lens group, a first detecting section to detect a first reference position for moving the first lens group, and a second detecting section to detect a second reference position for moving the second lens group. A control section controls either the first driving section or the second driving section so as to move a corresponding one of the first lens group and the second lens group between the first detecting section and the second detecting section at a predetermined timing.
A lens-group positioning method to be employed for positioning a first lens group and a second lens group, both of which are included in an optical system that further includes a first detecting section to detect a first reference position for moving the first lens group, and a second detecting section to detect a second reference position for moving the second lens group, the lens-group positioning method comprising:
An image capturing apparatus, comprising:
