The shapes are serface reflections bouncing around and passing through the aperture and the internal shapes are coming from a contaminated lens surface or coating damage, I'm sure this lens would benefit from being serviced, if it's possible.

I wonder if the waterhouse stop is in the wrong location causing the heavy vignetting...

Ahh, it's a transplanted lens from a fixed lens camera (Konica WaiWai disposable camera), so it might be half frame, plastic optics, so take care with cleaning.

I don't know what improvements are to be had, centering could be improved, it's not a lens that was designed to be perfect or even good, just acceptable @ a good price.

Firmware request:
-A button map for toggling the EVF & LCD
-Still waiting for the minimum shutter speed with auto ISO for my NEX-7 and A7r. I know it will never happen.
-Customize the display screen layout, I'd love to have both Histogram and level at the same time.
-More peaking options, being able to set peaking sensitivity and a threshold level.
-An RGB overlay on the histogram https://c1.staticflickr.com/1/602/20236258313_c604dd9522_n.jpg
-An option to return the focus assist zoom to one button press
-An option to return to how the NEX-7 handled playback, ie. center button to zoom, then you could use the control dial to zoom in and out, then center button to exit the zoom mode.
