Roger, this is the story what is that Leica feel:
Turning film winding lever makes many gears inside the camera to turn. Gear ratio and whole gears train distribution inside well designed camera housing make specific resistance and its feel on our finger.
Sound coming out of the housing due to gear movement is due to gear vibrations which is transferred to gear shafts, from shafts to shafts bearings, from shaft bearings to housing whose final vibration make what we hear as gear movement. Also vibrations from gear shafts is partially transferred to winding lever and finally to our finger.
Now that vibration on the lever coupled with torque resistance on the same make very specific feel in the finger.
We are all afraid from unknown things and familiar with known past. It is also why old people cannot get new generation, they are problem to them, but past is known so they like it better. Old Egiptians used toothed wheels to water the lend. Later on, through the history it is converted to modern involute and cycloidal gears. Today gears are not any secret to us and nearly just anyone knows for them. However, still noise quality that metal makes when contacting each other depend of so many things that some gears when run make unpleasing noise, while noise of well designed and made gears can be music to ears.
The next is sound of mirror-slap and work of the shutter-blades. That movements are so well synchronized and vibration transferred to the housing so well damped that we hear nice music out of the housing.
So winding the film, sound from well designed, sized, heat-treated, and made gears, and sound from mirror and shutter (shutter only for M) are very unique to Leica. They did not design camera, they design camera for pleasing feel and sound.
And what is also very specific to Leica, and make Leica feel is that all that movements and sounds do not looks like coming out of camera, because it is so well designed that we cannot feel on the camera body that vibration is synchronized with sounds. It all looks like is coming from some distance outside the camera.
I cannot say for ergonomic but that four things are LEICA FEEL.
And Leica busts creativity, yes. Everyone once hear that sounds and want to hear it again. It is simple very nice secret music we can hear only out of Leica, it makes mud. If we add Leica lenses story can go and triple.
I am professional photographer, former PJ, and just cannot find use of that camera. I am very sure also that no professional photographer buy it because he really need it for job. There are out ther so many "cheap" cameras to do the same job, might and better. And when come shoot for pleasure M8 is out of order at all.
So now tell me what M8 makes to be Leica specific, except the Red Dot. I think, If the M8 is with price tag $30 just children will buy it. Plastic gears, if any,....
