I don't know if a not perfectly aligned aperture blade shape is a production defect, I guess if it is by design it is a sloppy aperture design. About the blades retracting not fully, is that through the whole focal range? I have seen at least two lenses of which the edges of the blades were still visible when at max. aperture, but I do not know if it is normal for your lens type.

All images I see from the lens appear to have a closed aperture, I guess Sony E lenses close down when not mounted.
