ABSTRACT:
A photographing system includes a lens apparatus having an image blur correcting device configured to correct and/or reduce image blur caused by vibration, a vibration sensor for detecting vibration applied to the lens apparatus, a position detecting device configured to detect a position change of the lens apparatus, and a controlling device configured to control the image blur correcting device using a detection signal of the position detecting device. The photographing system reduces the influence of low frequency noise of a vibration sensor, while maintaining the quality of a vibration isolation function of the lens apparatus.
