CAUTION:

 

•The electronic iris is suitable for normal indoor use. When the EI/BLC switch is set to the EI-ONposition, do not use an auto-iris lens.

•If used under fluorescent light, the image may flicker. In such a case, change to incandescent lighting or set the EI/BLC switch to the OFF position and use an auto-iris lens.

•When shooting bright subjects, pay attention to the light angle in order to avoid or minimize the smear phenomenon effect.

When using an auto-iris lens (for indoor/outdoor use)

Set the EI/BLC switch to the OFF position.

CAUTION:

If conditions are outside the electronic iris operation range or more than the maximum illumination, it will cause saturation of the CCD. In that case, use a manual iris lens.
