Here is a picture of a caboose camera without the window and one with. The one without is definitely sharper but not wide vision and centered anymore. Look at how they image the top of the caboose. Not what I like but maybe I'll run it so the camera images toward the layout and it will be adequate...unless someone has an idea of how to regain central vision again. ]
Well it looks like my camera has shifted causing the off center view. I got to thinking that after examining the windows and they appeared to look identical and non lens like. My camera is very loose compared to the one is in the SR car that was difficult to remove. So if the camera doesn't shift, maybe removing the window is the way to go.
