Defocused circles of light look sensibly well for a lens with such parameters. You can't notice any distinct concentric circles but a bit brighter rim is easy to spot; also mechanical vignetting is very strong at the maximum relative aperture and it remains visible even on stopping down the aperture by 2 EV.
