Q: 8. Is the circular polarizer compromised at all by the dual function?

A: The dual function does not compromise the circular polarizer feature on the Haida PROII CPL-VND 2-in-1 Filter (77mm).

Q: 9. Can a Haida M10 drop in circular polarizer be used at the same time as an M10 Drop in ND filter in the M10 filter holder?

A: They can't. These drop in NDs go in the same spot where the drop in polarizer goes so if you want to use the drop in polarizer and the ND at the same time you need to get 100mm x 100mm 2mm thick NDs. Those square NDs you will go in a different slot than the drop in polarizer will go.
