>>3257702Mine has quite swirly bokeh and a lot of field curvature (the plane of what's in focus is curved like a bowl instead of being flat) and I think it had quite a bit of vignetting wide open.
I haven't used it for a long time and don't think I actually have many photos from it on this computer, despite it probably being one of my most enjoyable lenses to use. I'm fairly certain this one was taken by it though.
