Even if you open the IRIS wider (a smaller 
F-stop) than F3.4 when you set the zoom lever 
to the W (Wide angle) side, the IRIS is reset 
to F3.4 as you move the zoom lever to the T 
(Telephoto) side.
If you adjust the IRIS, the in-focus range in 
front of and behind the focused subject is 
changed. When you open the IRIS wider (a 
smaller F-stop), the in-focus range becomes 
narrower, and when you close the IRIS 
narrower (a larger F-stop), the in-focus range 
becomes wider. You can set the IRIS to a 
preferred value depending on the shooting 
scenes.
It is difficult to focus automatically at a 
lower shutter speed. Manual focusing with 
your camcorder attached to a tripod is 
recommended.
When you record images under a fluorescent 
lamp, sodium lamp, or mercury lamp, 
horizontal stripes may appear, flicker may 
occur, or color may change. In this case, change 
the shutter speed according to the power supply 
frequency in your region.
