Vignetting if using adapter for 77mm filter to 72 ...

Vignetting if using adapter for 77mm filter to 72 mm lens vs. using 72 mm ND filter?
Asked by: Ho
If the filter you are using is larger than the filter thread and can connect it with an adapter there will be no vignetting. Vignetting may occur if you use a filter with a smaller thread on a lens with an adapter.
