Being in the process of buying an M8 and at the same time struggling to accept the noise being generated by the internal winder I am wondering how much this noise will be reduced by Luigi's half case. Any experiences?
Cheers,

Luigi will not only make you a case, but he'll also remove the internal winder for you.

Since the Luigi half-case wraps 3/4 of your camera in wonderful leather, it does muffle the click-whirrr quite a bit.

That's what I was think about / hoping for. Any proof of the concept around?

Don't expect a big difference in noise. I have the half case and I would say it's 10% quieter.

Yes, but remember the inverse-square law:
So a 10% decrease in sound is significantly quieter to the subject of the photo than to the photographer who is milimeters away from the sound source (and usually hearing more via bone conduction).In physics, an inverse-square law is any physical law stating that some physical quantity or strength is inversely proportional to the square of the distance from the source of that physical quantity.
In acoustics, the sound pressure of a spherical wavefront radiating from a point source decreases by a factor of ½ as the distance r is doubled, or measured in dB it would decrease by 6.02 dB. The behaviour is not inverse-square, but is inverse-proportional:
However the same is also true for the component of particle velocitythat is in-phase to the instantaneous sound pressure
.
Only in the near field the quadrature component of the particle velocity is 90° out of phase with the sound pressure and thus does not contribute to the time-averaged energy or the intensity of the sound. This quadrature component happens to be inverse-square. The sound intensity is the product of the RMS sound pressure and the RMS particle velocity (the in-phase component), both which are inverse-proportional, so the intensity follows an inverse-square behaviour as is also indicated above:
The inverse-square law pertained to sound intensity. Because sound pressures are more accessible to us, the same law can be called the "inverse-distance law".

Well, thanks a lot for your input. I got my M8 today and I'll order Luigi's half case tomorrow. So, as soon as it arrives I'll record the sound of both versions and we'll see.
Stay tuned...
Stay tuned...

Remember to record the sound at different distances to see the effect of the Inverse-Distance Law.

I have a Luigi case for my M8. As someone said, I estimate about a 10% muffling of sound, if that. But as others have said, it sounds a lot louder when it goes off in your face than to someone off a ways. Honestly, in a truly silent atmosphere nothing other than a pocket digital (with the fake shutter noises turned off!) won't attract attention. I once took a single shot at 1/60 with an M4 in an empty church in Italy and it brought the priest running from behind a curtain. All that said, I think it would be great if Leica could separate the shutter recocking off to one of the rear pushbuttons, or at least until letting go of the shutter button, via a firmware command and menu item. It's not something I'd ship my M8 off to Solms for, and let them take it apart, even if it was free...unless the camera needed repair anyway, then I'd let them do it.
