Q
Are there (Female) threads on the front of this filter "Can you stack (77mm filters) on top of this filter".
A
For this 77mm ND filter,the lens cap/hood should be 86mm. 
Q
If i rotate the density from nd2 to nd400 and have a lens hood connected to the 77mm front threads, will the hood move?
A
by the way, when you use a nd filter , you better not add a lend hood ,the lend hood should move. 
Q
I’m not sure how its possible to fit a lens hood on top of it when there are no screw threads on the front of these filters. Anyone figured this out?
A
You need to use a Retractable Rubber Hood with an internal and external screw thread. You mount the hood first, then you screw the filter to the hood. You retract the hood then you turn the filter to desired ND adjustment. I can reach and turn it without retracting the hood. 
Q
Can you attach a lens hood on the 52mm lens?
A
hello , if you put a lens hood on 52mm filter, you need a 55mm lens hood
