PMW-350 Airport lighting color differences
 
Last night I needed to shoot something with my new PMW-350 at the airport. I discovered that the color of the runway lighting is adapted just by focussing or unfocussing. My colleague next to me (shooting with the older PDW-F350 (CCD cam) didn't have this problem.

Is this a PMW-350 issue? Or a Picture Profile issue? Or a CMOS issue? Not that it is disturbing me, just wondering why.....

If this change at 0:10s happened without user input I would definitly call it a problem.

But to me it looks as the white balance selector was accidentaly bumped...

Hi Zoran,

No I didn't bump the WB switch, it's only manual focus control I am touching to different positions. Of course that makes the image sharp and unsharp but I never expected it would have any influence on the color of the runway lights.

The non runway lights in the distance and periphery also change colours. Can you try it elsewhere, say a long, wide street or boulevard, a long bridge perhaps to see what, if any effect that may have?

From my observation, I agree with Zoran, re white balance selector or even the electronic colour temp button activated (although this may have a visible effect on the blacks). Your focus pull/push changes all the lights colours, not the runway only.

Gabor, I'm not suggesting for a second that you purposefully activated either user option, that is what I too am observing. Maybe there is an electrical issue.

More tests needed.

I have a PMW-350 with a Fujinnon 17x ZA lens and I have never encountered this problem with outside night light shooting.

Hope you get it sorted.
Cheers
