Can a step up ring be used to use the adapter on ...
Can a step up ring be used to use the adapter on a lens with a filter diameter much smaller than 82mm, like a lens with a 49 or 55mm filter diameter? Would it be fine to use one step up ring or should multiple be used? Will this affect the anamorphic effect at all?
I used a single 82-52 step down and it did not work as the rear of the adapter contacted the step down ring and damaged both. Use multiple steps to ensure the rear of the adapter will not engage with the rings or with the lens surface.
