GH1 Color Shifting Issue

I might have some bad news...I was playing around with my rig last night getting used to using the Shoulder mount/FF combination and I noticed something very disturbing in FHD mode...in standard mode AND with a manual lens (Tokina 28-70mm Pro). We have some light blue, purplely curtains in one of our rooms that exhibited this color shift when panning from the white of the wall to the curtains...it was if the computer was too slow and just changed the colour curve once movement had stopped. I looked at the LCD on the cam and thought I must be seeing things because I've been following this thread and using a manual lens in standard film mode. Rushed of the the plasma with card in hand and what do you know? Even my wife said "something is wrong with the curtains"...
I will post some stuff up when I get a chance...I'll try and make it soon.
 
Yeah that's the kind of thing I'm getting as well. Remember though, I'm using Standard mode and a manual lens.
 
Sonic-

Can you share your "Standard" mode settings? Have you changed any of the other parameters in the film mode settings?
 
Just uploaded a video to vimeo and just waiting in line for conversion. Will add a description when I add the link/embed. Sometimes I look at this and think...it's my eyes but I'll let you be the judges of that....in 28 minutes
 
Ok here we go. It's kind of hard to tell because of the jerky pull-down inflicted footage (and crappy format) but still to my eyes there was definitely 2 times in the sequence of shots that the blue shift happened. Maybe not as apparent as other footage I have seen but still there.



Here's the blurb I put on vimeo with settings etc:
Here is a crappy video that I shot while testing my follow focus/shoulder mount. It was shot in FHD (1080i 24p), Standard Film Mode (I might have adjusted after the first clip but the first is definitely standard), Tokina 28-70mm manual lens, a quick white balance was done on a previous evening to fluro lights, shutter was at 1/50 (and hence the banding you might be able to see), no pull down removal (obviously), Contrast set to -2, Sharpening -1, Color can't remember, NR -2.
Just a quite test to show that this blue shift can be experienced in standard mode with a manual lens. Hope this can help the community shed some light on this potentially devastating issue (think skies).
Cheers.
 
i definitely saw it on the first and last cut. is your WB on manual, auto, what is your WB? weird stuff..it's like it's taking the blue from the shadow and auto adjusting. anyone know what shadow correction feature does?
 
White balance was set using one of the 2 spaces provided for custom settings (manual then I guess). I used a white card (I think I did) under fluros. I stay away from auto anything as I'm trying to really get proficient with all the settings etc.
 
Panasonic didn't respond to the firmware requests but it might be worth sending them another mass message with links to these clips. If it isn't just limited to the kit lens then it's a pretty serious issue.

Count me in.
Anyone else want to test this with non-kit lenses, be my guest. I have another couple that I might try and give a whirl tonight with...Now my OCD kicks in and I spend my time looking for colors (or it seems, shades) that make my camera have a teary!:furious3:
 
I'm off out shooting in a minute. Got perfect blue skies here, so will test this out with a Four Thirds lens and see what happens.
 
I also saw this once on my GH1, when I was in CMM, SHUTTER priority mode, kit lens, smooth film mode (all settings -2). Back then I thought it was probably related to the aperture adjustments, resulting in a kind of "stepping" exposure compensation.

Actually, when in aperture priority mode (with kit lens and smooth film mode), I never saw that again.

I know it doesn't sound consistent with the finding, that also manual lenses are affected. But I would be interested if the above phenomenon can also be seen in aperture priority mode with the kit lens.

best regards

EDIT: forgot to mention that i am always using manual WB, by dialing in the Kelvin temperature
 
We need to hit Panasonic harder with a threat, that all posters on forums around the globe will be urged to boycott Panasonic GH1 products until this is fixed and give them a 4 week window to either fix it and/or issue a statement recognising the problem; posted by them on the major photo/video sites eg. dvx and dpreview.

Why not try asking nicely first?
 
We asked nicely about the mud and?

Nothing, why not ask them with some urgency for a change, there are plenty of alternatives around. They need to be a bit more responsive this time around, thats all I'm saying.
 
I have to say, at this point, I'm at a loss as to any idea why this is happening. I do still have my camera originals, and I'd be happy to send them along to Panasonic, if they need them.
