I thought that would have been obvious (that you can't use the rangefinder to check the lens' infinity focus), but maybe not. In any case, while you can use a ground glass screen at the film plane to check infinity focus (that's what I use), it isn't the most accurate method in the world. If you really want to set the focus precisely, you need to use a collimator. Since the camera is a Leica, you might want to consider this. Dang it, there used to be an article by Mark Overton on building a homemade autocollimator, but I can't seem to find it anywhere on the web. (This article here has a link to that article, but it's no longer valid.) I'll try to find it and post it. In the meantime you can search for info on collimators and autocollimators to find out how they work. |
