Q: 8. did you have for Sinnar??

A: If your sinar has a graflex back then it will fit. My old sinar did. Realize that if you are using a Nikon dslr that has a mirror you will not be able to slide the Nikon very far from center. This is because the distance between the sensor and the front of the camera where the lens would normally mount is too far and the edges will cast a shadow. That space is taken up by the mirror movement and is Calle the mirror box That's the problem I had with this adapter. It's well built but I could only use it near the center of the 4x5 area with my D800E. It should work fine with a mirrorless DSLR like th Sony alpha7 assuming you have the correct adaptor.

Q: 9. Does this work on the canham DLC 45 camera?

A: Unfortunately, I have no specification data on the Canham DLC 45. My experience relating this adapter is to use on Linhof Technika 45 camera and Sony alpha 7R. I modified the adapter to fit for Sony camera. It dose work very well. If the Canham DLC 45 has a same size of film back as Linhof and you use long focus lenses more than 150mm, it will be recommended. Under the recent difficult situation to get a film, this adapter will save your indispensable camera and lenses.
