Abstract:
1. A photographing system comprising: a lens apparatus having an image blur correcting device configured to correct and/or reduce image blur; 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 cause the image blur correcting device not to perform image blur correction, when a difference signal between an output signal of the vibration sensor and an output signal of the position detecting device has a frequency lower than a noise determination frequency which is specific to the vibration sensor, wherein the controlling device causes the image blur correcting device not to perform image blur correction, when the highest frequency of the output signal of the position detecting device is lower than the lowest frequency of a predetermined image blur correction frequency band and when the difference signal has a frequency lower than the noise determination frequency which is specific to the vibration sensor.
