not only looks chick ........

........ It also improves the "trigger-pressure sensation".
I find the button still a bit too high but comes by the strength of the release button.
The so-called security against working loose of the button:
a small rubber seal / a small rubber ring is placed over the thread of the knob.
Whether this will do its job? Will not turn out.

As I said, the button looks very good on the camera and fulfills the task of creating a better tactile feedback.
But whether one is willing to pay for a piece of CNC turned aluminum nearly 45 euros ......
The then everybody has to decide for himself.

Many Greetings
