Help resolving problem with mia_exposure_photographic

Hi!
I'm having a very annoying problem with mia_exposure_photographic node, if anyone could help me out it would be much appreciated.
The node is connect to my camera and a mia_physicalsky and it works fine like that, but when I introduce other lights to my scene they don't render.
I'm not sure if I have to change something in the lights to work properly whit the lens shader or it's just not possible..
Thanks.

What kind of lights/light shaders are you using, and what intensities are they at?

For testing purposes I'm using normal maya lights. spotligths etc.
Their intensity is the default one.
After some testing I've realize that if I increase the Cm 2 Factor on the mia_exposure_photografic the lights will star to show but the sun and sky light will be overblow.

You have to raise lights intensity instead. Using really high values, (eg. over 1000000) is fine especially if you are using quadratic decay (as you should).
