I have just bought the Nikon 14-24 lens, but as you know it does not wear filters, and I have some LEE-filters and a Singh-Ray Gold N´blue I would like to use. I know there is a solution, but it is not safe - I wrote to the technicall director (LEE-filters) and his answer was, that he did not recommend it. So now I want to use them on one of my lenses with 52mm diameter (Nikon 50mm f/1.8), but before I order a special "step down" ring in England and before I begin to believe in it, I would ask, if anyone have experience with using.... .....LEE filters (graduated ND.s) on such a small lens with so little diamater - sometimes I think that it is even hard to see the graduated line with a 77mm lens. Any experience before I go for it, would be very welcome. Thank you.
