Doron Kipper Posted February 13, 2008 Share Posted February 13, 2008 I borrowed a friend's 16mm Bolex with a Pan-Cinor 100 Lens. The lens itself has a viewfinder sticking out the side, and when I look through it, I see a perfect image....all the time. I can change the focus or f-stop and nothing in the image changes. How is this possible? Is the depth of field just that deep, or am I missing something? Also, it doesn't say on the lens if the markings are f-stop or t-stop. Is there any way to determine this? This is my first time using a film camera....and I'm basically wandering through the dark. Any help would be appreciated.

Nevertheless, I have dropped in here while doing some research on the development of the focusing system with Berthiot, this. The reflecting surface of your lens’ finder is situated in front of the diaphragm. By that you never see a change of depth of field as well as of the brightness. The diaphragm stops are relative ones, f/x. For focusing set the lens at its longest focal length. Link to comment Share on other sites More sharing options...
