A video camera for use with a video recorder having means for recording video signals on a recording medium and being operable to start the recording operation in response to a start signal provided by the camera, said camera comprising:
- a focus adjustable image pick-up lens system;
- an automatic focusing device for automatically adjusting the focus of said lens system onto an object, said focusing device producing a characteristic output upon completion of the focusing of the lens system onto the object;
- trigger means operable manually from outside of the camera;
- and
- means responsive to the operation of said trigger means and to the characteristic output of said focusing device to produce said start signal for causing said video recorder to start the recording operation.
A video recording system comprising in combination:
- (A) a focus adjustable image pick-up lens system for forming a picture image of an object;
- (B) an automatic focusing device for automatically focusing said lens system onto said object, said device producing an indication upon completion of focusing of the lens system;
- (C) picture image signal generation means for sensing said picture image formed by said lens system and for generating picture image signals;
- (D) recording means for recording said picture image signals generated by said signal generation means on a recording medium;
