No guys, it is just frustration that when people don't know an answer they feel the need to make up one. I didn't ask for speculation, I asked if anyone knows the answer to a question. And knowing an answer is not the same as thinking you know the answer, trying to guess it, or coming up with one. Yes, it's amusing to keep a thread alive with speculation, but it's not what I was asking for.
And there was no answer to my question on what causes the noise in recent cameras (I asked a single question btw, not two - I just had to repeat it because it wasn't understood). There is just speculation that it is caused by SR. But why would SR be noisy in just this particular scenario is not explained by the speculation. Why would SR be silent in all other use scenarios, but start acting just during Live View? SR is certainly capable to be active for longer periods of time without making noise, so SR cannot be the answer. It can be part of the answer, but not a full answer.
Here are some facts:
- SR can be active without the noise being present - this suggests it's not just SR
- The noise does appear in scenarios where the mirror is being held up - this suggests the noise might be from some motor holding the mirror up
Why the K20D does not have the noise is what I'd like to understand. It could be that my friend had a sample with a silent motor - I'll have to ask him to check if he gets any noise if he raises the mirror up for the cleaning procedure - or it could just be that Pentax used a silent motor just in the K20D - this phrase is of course entering the realm of speculation.
