18-200?
Is this possible on a Nikon 18-200mm lens? I made a small cutout the size of my pinky nail and can get the bokeh shapes, but only a small area of the picture is visible where the cutout is. The rest is covered by the surrounding black paper. I tried making a bigger cutout, similar result. My third try was about the size of 2 pinky nails, and still only about 1/8 of the frame has the image and the rest is black from the surrounding paper.
Does this only work on a 50mm prime? Does the physical length of the lens have anything to do with it?
Thanks!
