I am the new Director of Televison at a church in Texas. When the KY-29s we have are in focus in the middle of the image, the edges are out of focus. I have borrowed two lenses (both "Broadcast Lenses") from Canon and Angenieux, and the problem is still there. I've been told that the problem might be an incorrect contouring setup on the cameras. When countouring is turned off the cameras are impossible to focus. It's been 20 years since I've been paid to be an engineer, so I'm a little rusty. Any ideas?
