Calibration of the lens apertureTo be completed soon...
|
|
1) Inner barrel with the aperture block mounted. | |
2) The bronze ring rotates and actuates the cam, pushing the metal lever outwards. This lever opens and closes the aperture |
|
3) Approximate position of minimum aperture. This aperture has to be calibrated to the maximum f-stop of the lens (f/16). | |
4) The metal stop should be calibrated for maximum aperture (f/1.4). |
|
5) Cam actuating on the maximum aperture position. | |
6) ??? |
|
7) Aperture scale ring engages with the aperture mechanism trhough this coupling. This can be calibrated too. | |
8) Aperture actuated to the maximum aperture. |
