    I had 2 18-55mm kit lens one from nex-5n and the other one from a Nex-5r one of them the blades didn't make a perfect circle and one make a perfect circle but both take great picture I guess I sold the one didn't do the perfect circle
    I want to know if the blades are better when it make a perfect circle and why

    Bokeh is affected if the aperture isn't round, sharpness and diffraction too. Would have to be quite significant to matter. I had an 85/1.2 that had a tooth like aperture around f1.4-f2, created the same shape in any out of focus highlights.
