If you select VAR, the following items become

size. Set each item to the desired size.
To counter problems with very bright highlights
If the subject is too bright, the iris may close too much,
leaving the overall image dark, or the highlights may be
blown out. In such cases, setting the highlight clip function
on reduces the luminance range, avoiding problems from
the automatic iris correction.
In the AUTO IRIS page of the USER menu, set the CLIP
HIGH LIGHT item to ON.
To adjust the iris sensitivity
When you use the VCL-917BY lens, you usually need not
adjust the iris sensitivity because lenses are equipped with
iris sensitivity adjustment function.
In auto iris mode, if hunting or response delay happens,
adjust the iris sensitivity using the iris sensitivity trimmer.
