So here's a new one, what frequency is your lens during ServoAF?? :D

Please list below;

Canon 70-200 F2.8 L USM - approx. 8200Hz -48dB with a 30Hz width will remove the click

I'm a little lost as to how the resonant frequency of a lens AF motor holds any relevance to a specific camera!

autofocus servo af makes a click which any on camera mic picks up (i'm using the rode stereomic pro with dead kitten)

Sigma 30mm F1.4 DC HSM - approx 207Hz -48dB with a 6.3Hz width will remove most of the sound(enough to not be as distracting)
