Your proposal for adjusting stops is reasonable, at least for the larger ones. For thze smaller stops you might try using a set of number drills as gauges to transfer the settings. You could also just calculate the smaller openings from the largest, and again use drills for finding the correct hole diameter versus pointer position. A nice alternative would be a meter able tio measure light at the film plane. Besides ones designed explicitly for this task, you might try a meter intended for measuring exposure on an enlarger easel. Just make all measurements on a uniformly lighted wall.

Your right there was a stop and I just bent it down and the shutter now is able to open fully ( about a extra 1/2 inch in the overall diameter was achieved ..Now I have to figure out how to callibrate the f-stops to the new lens. Can any one shed some light on that?. I suppose I just use a set of callipers and measure off of the old lens appeture settings to diameter of opening and make a new plate and etch the stops by transfering the measurements.. ... jc _______________________________________________ Cameramakers mailing list [EMAIL PROTECTED] http://rosebud.opusis.com/mailman/listinfo/cameramakers _______________________________________________ Cameramakers mailing list [EMAIL PROTECTED] http://rosebud.opusis.com/mailman/listinfo/cameramakers
