I have a Panasonic GH* and I use it to shoot video. My current setup is using a metabones speed booster ultra .** EF -MFT mount adapter and currently a canon **mm f*.*. Recently when I turn on the camera it asks if I want to change the focal length and I have changed it to **. I've had it a few months but this past Friday on a shoot I noticed that I could not adjust the aperture (f-stop). It was in Manual mode. It displayed *.*. I turned off the camera, took out the battery, reset the settings back to the factory settings and nothing helped. Before I reset to factory settings it would continually cancel out of the menu over and over again. I'm not sure what else to try to fix this problem, or if it's a setting problem.
