I use an Amedeo S-mount to LTM adapter (second copy actually, I had sold the first one together with a Millennium Nikkor 50/1.4) and it works with my screwmount Leicas (Leica IIIb, IIIc, IIIf) and my M-Leicas using an LTM to M-mouunt adapter. I have not experienced any focus problems but the only S-mount lenses that I have left and use are the Nikkor-H-C 5cm 1:2 and the W-Nikkor 35/2.5.
The second adapter was from another batch, the shape of the adapter base had changed to a knurled design. That adapter needed some lubrication initially because it was rather rough (I applied a tiny amount of white grease for lenses sold at Yodobashi camera in Tokyo) and now it turns very smooth.
