Originally posted by orlovszki I made recently a short clip in a church tomb (in complete silence) and when I saw it at home I was shocked to hear such a loud background noise that everybody asked about it.
click this youtube clip I talk about.
Ned Bunnel commented about this in his blog when the K7 was released. The background noise is from the shake reduction system and, unfortunately, there is no way to actually turn the shake reduction off (even when switched off, it is still needed to hold the sensor in position).
The only alternative is to use an external microphone, since the camera itself is not capable of completely silent operation.
It's something we have to live with to get the advantage of shake reduction with every lens.
