Question about aperture blades on my fa 31 ltd

Hi, I've noticed that the aperture blades of my fa 31 ltd ar far from describing a "perfect circle". Is this normal? Does this affect image quality? Two imgs I've taken:






Thanks in advance.

I don't know, does it affect quality?

Have you noticed any strange artifacts or fugly bokeh?

You wouldn't really get much bokeh at that aperture.

You have an aperture blade that is not fully closing.

Thank you for your replies. Apparently it doesn't affect image quality and from f1.8 to f5.6 it has a shape more similar to a circle. I'm definetly not going to worry about it anymore.

Thanks.
