About the Iris F-number
Blurry effects due to “small aperture diffraction” may occur when the diameter of the iris becomes too small. When this phenomenon occurs, the F-number on the screen turns gray to warn you that the diffraction F-number of the iris has been exceeded.
You are recommended to make appropriate use of ND filters to prevent the F-number from turning gray.
