Digital camera

A digital camera comprising:

• an image sensor for capturing a subject image;
• a mirror movable between a first position to enter an optical path from an imaging optical system to said image sensor, and a second position to withdraw from said optical path;
• a driver for driving said mirror;
• a first detector for detecting an in-focus condition of said imaging optical system on the basis of an image signal from said image sensor;
• a second detector for detecting an in-focus condition of said imaging optical system by a phase difference method;
• a selector for selecting either said first detector or said second detector;
• and
• a driver controller for when said selector selects said first detector to detect an in-focus condition, controlling said driver to move said mirror to said second position and when said selector selects said second detector to detect an in-focus condition, placing said mirror at said first position.

• a second detector for detecting an in-focus condition of said imaging optical system by a phase difference method;
• an operating member for image capture being movable from a first operating position to a second operating position which is a further pressed position from said first operating position;
• and
• a focus controller for when said operating member for image capture is at said first operating position, placing said mirror at said first position and driving said imaging optical system according to a result of detection by said second detector and when said operating member for image capture is at said second operating position, controlling said driver to move said mirror to said second position and driving said imaging optical system according to a result of detection by said first detector.
