Back in 2013 Leica Camera AG purchases Sinar Photography AG. Here is some more information on the Sinar system and Leica S camera integration:
The Sinar p MF-L is designed especially for photographers who wish to avail themselves of the unique characteristics of a Sinar view camera while using their Leica S medium format camera body.
Sinar p MF-L benefits:
- Unlimited creative freedom for image composition
- Superb quality with Sinaron HR lenses
- Exact control of perspective with tilt & shift functions
- Selective sharpness is precisely evaluated on the view camera
- These most important creative tools in photography are now available for Leica S users
- The Leica S is freely positionalble from vertical to horizontal format
- Use your existing Sinar p2 or p3 camera with a conversion set
There are also several Sinar adapters/conversion sets for Leica S:
- Sinar p3-df MF-L for Leica S & S2
- Sinar Conversion Set p3/p3 MF-L
- Sinar Conversion Set p2/p2 MF-L
