Change white balance in greenscreen studio when changing focal length

Hello there,

I am a newbee when it comes to filming professional in a green screen studio and i have got some beginners questions:

-When i film in a green screen studio with a zoom lens 14-42 mm and i have set my white balance whilst the lens was on 14mm. Do i have to set a new white balance as soon

as i change the focal length to 25mm? Cause changing the focal length of my lens also automatically changes my aperture.

Thanx in front

Greetz Lenny

Hey Lenny,

No, you should only have to change your white balance when the lighting conditions change. White balance is effectively just a compensation for lights of different colours. Iris, focal length, focus, etc, have no effect on it.
