SKU: KF01.976
Q
Is the thread on each side the same size? i.e can i stack a your 77mm cpl on the 77mm nd1000
Answer Question
A
Yes it is the same size. This means you can also fit your lens cap on whilst filter is in place.
However once the ND1000 is in place you cant see through it to adjust the CPL. You would need to fit the CPL, adjust image to suit and then fit ND1000.
Also bear in mind CPL's often loose a stop of light so you could end up with an 11-stop filter (ND2000 equivalent if they ever made one).
