Note:

If a previously programmed iris table is re-edited,

 

the corresponding table must first be loaded

 

from its memory area as described above.

 

The handwheel must then be turned in the table

 

menu (TBL LOAD, TBL DEL, TBL EDIT, TBL STORE)

 

until ‘EDIT’ is displayed in the second line.

 

Confirm with the SEL button to return to the edit

 

mode for this table.

5.5.1.5Important instructions for programming the iris of the lens

•If the lens has a CLOSE position, this must also be defined, as the iris table only applies up to the last value before the CLOSE position! When assigning, the CLOSE position is programmed after the highest possible T-stop setting.

•If the T-stop scale of the lens being used is linear, it is sufficient to enter just two T-stops, which must be at least four T-stops apart, in order to define the iris table. If the T-stop scale is not linear, all the T-stops must be assigned individually.

•For compensating the exposure, only the range between full T-stops may be used! Example: the iris scale of the lens reaches from T2.2 to 22. The values for T4 and T16 are assigned. The resulting usable range rechaes

from T2.8 to T22, as T2.2 is not a T-stop from the standard T-stop range (this would be T2.0, for example).

•The display shows full T-stops followed by the tenth of a T-stop. Example: T-stop 2.8 plus half a T-stop is shown as 2.8_5. The tenths of a T-stop are linearly divided between the two full T-stop positions.

•To check the image in the viewfinder, the iris can be opened completely by pressing the OPEN button. The iris remains open until the OPEN button is released again. This does not alter the programmed settings. The OPEN button is without function while the camera is running.
