Flicker while zooming: video + low light

Okay. I'm officially bumming about this issue... I had hoped to do focus racks with the stock lens but I have no idea how to avoid this click-n-flick
 
I see this issue too, but one aspect of it could be to make sure the Auto LCD brightness is off. I was seeing the brightness change without zooming and realized I turned on that weird feature at some point.
 
The LCD auto brightness setting should have zero relevance to the actual video that's laid down.

i think you're confused on what a rack focus is...right? you're not zooming the lens any when you rack focus, just changing the selection of focus from one area to another. that wouldn't cause you lens to zoom at all. unless you want to do a jaws effect, in that cause...a nikon zoom lens.

The issue of sudden changes in exposure can happen in other scenarios than simply zooming (eg in shutter priority with fixed ISO).

Oops :Drogar-Smoke(DBG): I meant zoom rack if that's the correct term... Basically zoom in or zoom out to place the subject in it's context or pick the subject our out of the context.

I thought this was one of the big selling points of the GH1... hype like 'maintains focus while zooming' - what's the point if the result is has like 5-6 'blips'?? :crybaby:

Works absolutely fine with my adapted manual zooms... but I don't have anything with the range of the 14-140!
 
I also get the light bursts and clicks when zooming, whether the f-stop is changing or not. I didn't notice this when I first got the camera, but that doesn't necessarily mean it wasn't happening. I also have noticed a slight whirring noise when the camera is on that I didn't notice before. I'm curious how many people have noticed all of these "symptoms" on their cameras.
 
Just a little tip-

I was able to reproduce this problem with the kit lens without any zooming or focusing (lock off) in a properly exposed scene.

It would only happen during recording, not during preview, while shooting underwater. Of course PL lenses have no such problem. When I get some downtime next week I'll blog about it in detail (with pictures.)
 
Hot!

Try this? std. pasm modes, lock ae button, zoom, no clicking!!! switch to cmm clicking/stepping noise again, interupts bumps video exposure!! f/w issue fix!
