Another photo taken yesterday afternoon which I am pleased with as the Pentax has capture plenty of detail in shadows and highlights. I am 100% that reviews / testers can be ignored when it comes to tests like this because.- Most of the time they use JPEG with default camera settings or if they do it properly with a RAW file who knows if they they know what they are doing. In fact most testers who do use a RAW file do state they used a default setting which isn't much different from doing it with the camera JPEG.
Zenitar 16mm at f5.6 corrected in PT lens. RAW.
Does a falling tree make a noise if there is nobody there to hear it?

I see you use PTlens. Did you buy it or did you get the free licence.
Somehow, I seem to be too stupid to get it working.
Is there a special thing I have to consider?

That's a really philosophical question. Many theories have been discussed here!
I would say, it is a matter of definition. How do you define the meaning of "noise"?
Is it
a) air that is condensed in waves then: yes, there is a "noise", since the waves are produce by the falling tree.
b) the manifestation in a human brain of condensed air waves recorded by the internal hearing organs, then: no, there is no "noise", since there is nothing that can translate the air-waves into a "noise".
That's my view on that.

There is also a third option conceived in the 20th century: there is no noise if there is no TV coverage of it.
