Aperture jumps - without Shutter, ISO and aperture-values changing...- Why?

[thomas diehl]

I am a new GH2 owner and have set ip up for video as suggested in the gh2-setup - thread.
But still experience one problem: when i pan the camera I can clearly see "aperture jumps" (image gets brighter or darker). But I don't know why?! - Shutter, ISO and aperture-values don't change. Just the -3/0+3 -number - but that is just an indicator, isn't it?!
What am I doing wrong??

you sensor is just seeing different light values

 

[thomas diehl]

but it behaves in a very different way than my af101 - with the same lens.
does not make sens to me.

What lens are you using- could it be a variable aperture zoom?

Try shooting in Aperture Priority and see whether the problem goes away.

thanks for trying to help
it is the 14-140 pana-lens - and no - a-priority did not help.

two more newbie-questions: when i focus manualy my af101 displays the distance. the gh2 does not. right? or wrong setting?
is there a way to change aperture more smoothly (like the wheel at the af101)?

 

[thomas diehl]

it is not a variable aperture issue, i think - because it happens when i pan - without zooming.

It's just the screen popping exposure right? It's on GH1 aswell, never managed to find the menu setting to turn it off (if there even is such a thing). But if it's the same in Record then ur doing it wrong

I used to own a GH1 but I never noticed it. Strange. I was a bit surprised when I first saw it happen with my GH2, which doesn't happen once the record button is pushed.

I was just looking into this last night. Setup menu page 2 has a LDC MODE setting (brightness control). I believe AUTO is the default. Changing it to a 1, 2, or 3 value which locks it.

Two things...

1- Are you seeing this during recording or only when the camera is stopped ?

2- Are you shooting in full manual mode ?

Use the AF/AE LOCK function.

There is a button on the back just left of the wheel.
In the CUSTOM settings, page 2, set the "AF/AE LOCK" to AE, and "AF/AE LOCK HOLD" to ON.

When you are panning, push the AF/AE LOCK button and the camera will stop adjusting the values; you will keep the initial AE level in this shot. You will see "AEL" in the bottom left display corner when the lock is on.

You can leave the display on auto: LCD MODE: A* (SETUP, page 2).

I hope this will work for you.

Thanks! That worked.
