Swappable diffuser removal/installation: CINEFUSE 2
November 2007 update: The new CF2 and CF2Le are no longer "sandwiched". Install them as you would CF3 or CF3L!
Note: The Brevis diffusers are delicate. Handle only by the edges…and never touch them with your bare fingers. Micro-fibre cloth or lens tissue work well.
1. Remove the adapter from your camera, and set it with the achromat down, on a clean, dust-free surface. Make sure your hands are clean, and you have a microfibre cloth or lens tissues on hand. You’ll also need the small allen key provided with the Brevis unit as well as a small Phillips screwdriver (star).
2. There are four set screws at the rear of the unit that penetrate the carbon fibre tube. Remove them by unscrewing counter-clockwise.
3. Lift the carbon fibre tube complete with lens mount straight up and set it aside.
4. You should be left with the diffuser plate and rear ring assembly sitting in front of you. Grasp the diffuser plate with one hand, lifting the whole unit slightly off your work surface and with the other, unscrew the two Phillips screws holding the diffuser plate on.
5. Set the unit down and remove the GG retainer plate. Do not remove the stock diffuser.
6. Handling the diffuser option screen by the edges only, blow off the surface with dry air, and place it over the stock diffuser so that the shiny side is up, and the diffuse side is touching the stock diffuser.
7. Place the diffuser option holder (has two holes in it) over top and carefully align it so the diffuser drops in, the motor slot is over the motor, and the two screw holes line up.
8. Tighten the two screws down, again supporting the GG plate with your free hand. Check and then check again to make sure the two diffuser are tight to each other and the screws are fully inserted! If you turn the adapter on with the diffusers loose you will damage both!
9. Affix the carbon fibre ring back on and you’re done. There is a notch where the switch body sits, so it can only go back on one way. If there are any dust or carbon particles inside, now’s a good time to blow things out, clean the internal surfaces of the dust shields etc.
