I was looking for an easy to use sunshield for the Panasonic GH3. Nothing was on the market yet except for the Zacuto VF, and that required that you hold the camera to your eye.

 I devised something out of black and white foamcore. It is lightweight and slips over the flipped out viewfinder so it can be oriented in a number of directions.

It can be  placed flat in the camera bag for travel.

Pop it together to use. There is velcro on the edges by my thumb.

I held it in place with a rubber band.

I attached the camera to a monopod for almost all of the shooting in Sierra Leone. In come cases if I need to move, I collapsed the monopod and placed the end under my right arm to anchor the camera there and used the strap around my neck for another support point. This left both hands free to support the camera and work the controls.
