I have an older Fujinon 75mm lens with very limited angle of coverage. Often in using the lens with extreme front tilt I get some vignetting. I understand why and to compensate I'll often lower the lens. With the Lee Filters this is diff icult to do since the camera bed often interferes with filter movements (split N D). My question is will the use of the back tilts cause less vignetting than th e front standard?
