So I set this up and focused at 1.4 than I went over to upper left and tried to focus at 1.4 and given the astigmatism its really hard to focus there at 1.4. My CV 40 same thing. So I tried at F2 and really given what you will see here at 1.4 where it is pretty ghostly looking. Which in a way is kind of cool but really F2 really does improve things.
Let me just show the 1.4 crops to give you a idea here. Im focused on that Peak roof building.
