Claim:
A focal-plane shutter comprising: a board including an opening; a leading blade and a trailing blade capable of opening and closing the opening; a trailing blade lever capable of driving the trailing blade; a first lever connected to the leading blade and capable of driving the leading blade; a second lever arranged coaxially with the first lever, and having an engagement portion abutting with the first lever to push the first lever such that the leading blade opens the opening; a self-holding type solenoid capable of holding the first lever such that the leading blade opens the opening in a state where the self-holding type solenoid is not energized; a leading blade electromagnet and a trailing blade electromagnet respectively capable of holding the second lever and the trailing blade lever in a state where the leading blade electromagnet and the trailing blade electromagnet are energized; and a set lever setting the second lever and the trailing blade lever such that the second lever and the trailing blade lever respectively abut with the leading blade electromagnet and the trailing blade electromagnet, wherein a first mode, where the second lever and the trailing blade lever are set in a state where the leading blade and the trailing blade open the opening, or a second mode, where the second lever and the trailing blade lever are set in a state where the leading blade closes the opening and the trailing blade opens the opening, is selectively switched.
