Looking at the crops below, we can see the coma degrading the diode’s circular image. Without a doubt, the fault takes a toll on the side-of-the-frame image quality.
Astigmatism, on the other hand, gives us nothing to worry about. The level of the fault reaches no more than 3%, which we consider a very good result.
