Thanks a lot

Looks to me like the white shading is off. The green seems to be right across the top and appears to be more apparent by the bright light back ground.

I'm only a newby but have you balanced the shading?

Steve

Mike Laisney · August 17th, 2009, 09:57 AM

I did the white balance

the white shading is setup on preset mode

so what can I do?

Eric Deyerler · August 17th, 2009, 10:36 AM

You can set the white shading!
And make another test, to see the difference.

I have seen that with my HM100 when there is a bright light just past the edge of the image.

I actually have seen it on a few cameras over the years when there is a bright light just past the edge of the image.

there is some picts about this Problem, I don't know what to do now :-(

thanks

It was the fujinon lens mine was the 17-1 lens
I now have the canon I and have no problems. Its the coatings on the fujinon lens and the green you are seeing is the light coming into the lens is flaring and causing a lens flair.
You can try to minimize this by reducing the flair with a card or for instance try putting you hand while this is happening on the top near the lens shade and see if that helps. All lenses can exibit flair . My lighting guy is always setting up filters in the studio to reduce flair from the lights . The canon lenses seem to be alittle better maybe more coatings ?

Mike Laisney · August 17th, 2009, 12:59 PM

Thanks Doug

but I have the canon, so the problem is coming from the lens or the camera ?

I just bought this camera almost 2 weeks ago,

:-(

Do work on your lens with a filter to protect the lens, this could be another point for the greenish light.

Mike Laisney · August 18th, 2009, 12:29 AM

I have a 82 mm UV filter to protect my lens , with or without same thing :-(

Eric Deyerler · August 18th, 2009, 01:01 AM

I see in some tests that lens protection-filters can
cause color-effects, mirroreffects and something else,
also the CAs will be more visible with many UV-protection filters,
because the problem is the multilaxer-coating which
causes reflections.

Les Howarth · August 18th, 2009, 06:30 AM

Viewing the last pic img136 it really looks like the reflection of a window just above the frame. I can see dark divisions in the green - like from the vertical parts of a window-frame.

If so the light is bouncing from either a filter on the front of the lens or somewhere inside the camera like from the sensor or the area above/(actually below in this case as the reflection is at the top) back onto the rear of the lens.

Have you tried flagging the lens on top - you could try a piece of card or black-wrap. If it works the answer would to stop that light from getting to the lens - a flarebuster or mattebox/shade with a french flag like the Genus and/or rectangular matte or "eyebrows" at the front of the lens like Vocas and others.

The rubber hoods that come with a lens really don't do a lot to shield the lens at all.

Mike Laisney · August 18th, 2009, 09:36 AM

Hi
I tried witout Uv filter and still the same,
I tried to flag with my hand in the top lens hood and the green light disapear.
So this is the problem, but I don't think it's normal at all,
I never encounter this problem with my canon XL2.
I try to contact my local dealer to do me an exchange

but what do you think the green light come from the lens or the camera ?
