Not really. I have at some point decided to stay with Nikon when it comes to that camera type. The Z line works well enough with Leica lenses relevant for me and their lens line-up is more than sufficient for my purposes. If at all, I would look to buy a used SL or SL2. Service turnaround with Leica is also a big issue for me.

Man liest immer nur das, was einen gerade passt. Das Kurbeldings als China-Kopie findet man bei Ebay unter "leica rewind crank mp". Damit gibt es dann vielleicht weniger innere Unruhe und trotzdem einen eleganteren Rückspulknopf für die Zeit, wenn der Strassenalltag einen nicht so in Beschlag nimmt. Die Originale werden mit Gold aufwogen.

Man kann doch so ein Kurbeldings and den alten Rückspulknopf klemmen, dachte ich. Wenn es denn sein muss. Meist wird 36x weniger zurückgespult als ausgelöst. Eventuell nicht so extrem wichtig.

Amazing shot

Not everywhere

You can probably call them.

Of course the Q3. This is a Leica forum.

The tech specs of Leica's S-Adapter-H list the extension tubes as "not compatible". Don't be too surprised that is may not work in some circumstances. I am more surprised it actually does work in my case. If you own the 120S, I would look into the proposal of @mgrayson3. High quality close-up lenses are often better, because they don't put the lens into a focus distance area it was not designed for.

I just checked for you: my S2 with S-Adapter-H, 13mm extension ring H and 100HC orange dot takes photos fully open and stopped down. Even the leaf shutter in the lens works.

Q3

A rangefinder camera essentially has the viewing and image taking process detached and the viewing happens through an optical path. That has implications: You see what happens in real terms - it is like looking through a window versus looking at a monitor showing the very scenery. There is no delay The finder shows what the finder shows and the sensor sees what the sensor sees. That is never the same and (if you care) requires some imagination. Examples would be depth of field not visible in the finder, same for color adjustments and exposure Releasing the shutter only copes with the imagine taking process - not with the image viewing process. No mirror no move, no blackout etc There is no boost in low light In case you use tighter lenses than what the finder is showing, you see outside the frame - it works best for most with a 50mm lens on a camera with a 0.72 or 0.85x finder The magnification of the viewfinder does not change, which is a problem with longer telephoto lenses. The frame only gets smaller All this to some is a plus, to others a minus. It is a matter of your viewpoint (no pun intended).
