APERTURE CONTROL
Your Irix lens is equipped to function with your
camera’s electronic aperture controls. It also com-
municates the aperture information to the came-
ra’s software for display and EXIF data.
This feature allows you to fully utilize the creative
aspects of lens aperture in conjunction with your
camera’s metering system and autoexposure set-
tings.
There are a few important points to know about
your lens and its aperture settings:
1. Using an aperture setting higher than f/16 may cause some
lack of sharpness due to an optical phenomenon known as
diraction. This is not a defect, but a natural occurrence in all
optics.
