Hi guys. i don't know if this question has been asked before.

how do i avoid getting over exposure when following a subject from a point where i've pre-set my settings( iris; ND; shutter speed), into light that i have no control of (sunlight) and i can't stop to reset?

Hope i'm making sense.
 
That's simply not possible. You need to either use auto iris, or control it by hand.

It depends on the difference in the lighting situations, but you might want to try to under-expose the preset, and then maybe bring it up i post. But you will not get acceptable results.
 
Depending on how severe the change in lighting is, I would say expose for the bright situation and let the first part of the scene fall into shadow. I have seen this happening more and more in TV drama (TNT stuff, 24, etc...), where it is OK to let things go really dark, or almost black.
 
The exposure range of video is narrower than the change in intensity from indoor light to outdoor light. If the change is too great then the settings will have to be changed to get a good exposure under both conditions. Also, of course, the color of the light is going to change radically, which means you will probably want to use an "A" and "B" white balance. You can turn autoiris and ATW on and then get a changing exposure for the shot. You can also speed up the transition from one setting to another using the USER buttons and the SCENE FILES to make the switch-over faster.

If I knew in advance and could block the shot, I'd probably store an inside and an outside setting in the SCENE FILES and USER buttons, an inside and outside white balance, and then I'd use the "Manual | Auto" button. I'd shoot the transition (like walking outside) in Full Auto, and the inside and outside in Full Manual, and then look for a place to hide the cuts. For example, I might have the actor walk into the camera and completely block the frame so I could cut from the inside to the auto/transition shot.

Another thing I've seen is to just keep the interior settings and let it blow out during the transition, which gives almost a fade-to-white effect.

Good luck!
