I have Singh ray 2 stop Graduated ND with soft step. I find it very difficult When i uses them with canon 17-40 f4L lens on Canon t2i which is a crop sensory body. The problem i face is that since it is soft step, i am not able to use the darkest part of it(which is true 2 stop) for the bright part of the scene. In the holder i have to move the filter all the way down which bring the soft dark part of the filter on the part of scene which is not properly illuminated. And this results in a bad exposure.

Does anybody else face same problem, and if yes how do you get around it
