With many zoom lenses like 18-55 mm, when you zoom in the apperture goes down and the image gets darker. It's possible to rise the shutter speed/ to make the shutter speed go down in video when the apperture changes while recording ?

The exposure lock feature might help here, but to get perfect compensation while recording... it's almost impossible.
