77mm ND1000 (10 Stop) Filter Nano-X Series - Multi-Coated Optical Glass, Fixed Neutral Density Lens Filter
SKU: KF01.977
Q
Does this filter have outside threads to be able to screw on another filter?
Answer Question
A
Yes, there are threads on both sides (I just tried), which can be useful for adding a polarizer. However, you can just as easily have the K&F ND1000 filter stacked onto the inner filter.
