C100: Screw on ND's

Does anyone use screw on ND filters in conjunction with the internal ND? or just go full external?
 
Matt, I've often wondered the same thing. I'm sure there are some situations which might call for a different selection of NDs or other filters, but I have no idea how often those situations would come up.
 
C100 MKI only has 6 stops max ND. Not enough to hold native ISO so I use the Tiffen VariND only for exteriors
 
I keep a 3 or 4 stop ND permanently mounted on most of my lenses. The C100 Mark II has more latitude at 850-5000 ISO than it does at 350-800. Even in a well lit room you often can't shoot above 850 when your f-stop is wider than 2.8.

This gives me a full 9-10 stops of ND if I go outside and need/want to shoot with a shallow DOF.
 
There is one very important situation where my variable ND is better than the built ins: Doing an outdoor interview where the clouds keep coming and going. That way I can roll the exposure where the audience doesn't notice. If I were to use the wheel on the handgrip the audience would see click stops. Otherwise I would not use the variable ND, I'd probably forget to take it off when I do the interiors.
