Hi all, I am currently using a Linhof Technika V by now. I've recently found a guy (he is a Sinar fanatic) that says that he saves a lot of time with the Schleimplug and double Schleimplug operation with his Sinar camera. I've always thought that tilting movement was preferred to be done through the optical center of the lens. Any feedback? Rgds. Martin www.martintrucco.com.ar
