55mm F1.8 ZA -- aperture blades visible?

Just got the 55mm 1.8 and seeing what kind of images it makes.

The lens makes quite a bit of focus and aperture change noise ... but that's OK with me.

But when I took some images in low light, the aperture blades were clearly visible as a colourful vignette (see photo) in the viewfinder.

The rings show up clearly enough when you push the exposure just one stop but I have pushed it five stops in the screenshot to make it super clear.

Is this normal for this lens?
