dead pixel! noooo!! at DVinfo.net

Cesar Ruiz · March 25th, 2003, 08:03 AM

I have a dead pixel on my brand new GL2. It only shows up (is noticeable?) when the gain is at 18db and the shutter set to to 1/8 or 1/15 second.

Does anyone know if this dead pixel, with time, will show up at 0db gain and 1/60 second?

Even at 1/30 second and 18 db gain, I can't see it.

I don't want to send it in if it will never get any worse.
Especially after some stories I've heard of cameras coming
back with more problems.

I don't forsee having to use the extreme settings
on event videography.

Anyone know a definitive answer?

Thanks,

With such extreme settings it is hard to tell whether the effect
your seeing is a dead pixel. Especially since you can't see it
anywhere else! You can try some other tests with the lens
cap on for example to see if you can find it there....

Is it a dead pixel or a hot pixel? Hot pixel may look like a white spot when at high gain settings.

If it does not intrude into your normal video shooting, it is not a problem.

Thanks for the responses.

I guess it was a hot pixel. It would show up
as a white spot at high gain settings.
Eventually I started to notice it with
1/60 shutter but only at 18db gain.
But shooting under regular conditions
made it undetectable.

Are hot pixels common? Can they develop
over time?

As it turns out, I sent the camera back
to the dealer and should be getting
a replacement today.

Hot pixels are not unheard of, especially in the GL1, but most folks do not have a problem with them. They may become apparent over time. Fast developing hot pixels can be a concern and should be addressed with Canon under warranty.
