4- The focal has to be entered like: 00035 for 35mm, 00125 for a 125mm, 01000 for a 1000mm. (Five digits begining by 0 and finishing by your focal length)
Use the correlation table next line. To simplifies your job, write the apertures's sequence on a paper.
F4.0: 0 | F4.5: 1 | F5.0: 2 | F5.6: 3 | F6.3: 4 | F7.1: 5 | F8.0: 6 | F 9.0: 7 | F10: 8 | F11: 9
After each aperture has been chosen with the control dial, validate the value it with Fn button (press, release and wait).
For a 35mm, it will be: | F:4.0 | Fn | F:4.0 | Fn | F:4.0 | Fn | F:5.6 | Fn | F:7.1 | Fn |.
For a 125mm, it will be: | F:4.0 | Fn | F:4.0 | Fn | F:4.5 | Fn | F:5.0 | Fn | F:5.6 | Fn |
