Anyway to use high speed flash synch with S cs lenses on SL3?

Just curious if it’s possible to use Leica S  central shutter lenses with high shutter synch speeds on sL3.

Some of you guys must know . It would really be a nice trick to have in the bag.

Thanks.

Not possible.

I have asked Leica about this, because the fuji GFX has an adapter to use Hasselblad lenses which has a button which allows you to use the CS shutter on them. 

It's an oversight of Leica not to design an adapter which has something similar.

It's likely a power issue.  The central shutter on the S lenses needs power to work it and the S batteries were larger.  I don't know the layout of the pins on the SL or the S system, but it may just be incompatible.  The CS also works differently from the Hasselblad and other older CS lenses.  It opens before the shutter starts, the shutter opens, then the CS closes and the camera shutter closes.  The system was designed to work with the S camera and the SL system may just not have what it needs to do all those things.

Leica has made some incredible adapters.  The L to R adapter reads the ROM information and gets the f/stop and the focal lenght of the zooms.  I'm sure they would have added the CS shutter if it was reasonably feasable.
