I just purchased a Canon C100 camera. Before purchasing the camera I read several reviews regarding the unusable viewfinder and lcd screen was. Many folks decided to buy the Zacuto Z Finder which was made specifically for the C100. I asked around and a fellow C100 owner told me about the Sachtler Mini Hood for the C100 you can buy it here. The hood works great in the sunlight and is pretty easy to place around the C100 screen. I use the waveform monitor in conjunction with the hood and my video comes out looking great. What is really cool about this product is that it is only $26.00. So if you wanted you could buy two of them, one for use and one for backup in case you lose one of them. Here are some pictures of the hook on my lcd screen.
