I have a Canon YH18x6.7KSR lens on my GY-DV 500 camera (love it), but, it¹s
picture is always too hot in auto iris.
Do you know if the auto iris on the lens can be mechanically changed (other
than manually) to stop down to a acceptable level?
Even with setting the camera to factory defaults, it is still hot, so I
think it must be in the lens. Canon checked the lens
and said it is working fine, but gave no hint as to how to keep the auto
iris from being too hot. They didn¹t even answer my question about it which
is why I sent it to them in the first place.
Is there any ³mechanical adjustment² I can do to the lens to make the auto
iris stop where I want it *in auto*, instead of the
lens making the ³default adjustment² and the picture being too hot?
I¹ve contacted JVC and he told me, other than the backlight adjustment, the
camera couldn¹t be set any other way.
This cameras picture is running way hot (about 3 f stops sometimes) and it
was just serviced and checked at JVC.
Others have had the same problem but I don¹t know what they did to correct
this. I¹m figuring there must be a mechanical ³set-screw² or
"trim-pot" that determines where the auto iris stops under different
lighting conditions. It¹s very consistent, but just over-exposed in auto.
Do you have any suggestions?
Thanks for the help.
