Zoom problem with volumetric

Hello.
When I add volumetric and set the light in scene everythin is ok, but when I whant to make some closer view of my model, start to zooming camera, all the light in scene becomes sharper and brighter. So all my light settings not working with new view (after zoon).Is there the way to fix it? Or every time when I change the camera view (zoom), I have change settings of light?
