You can get smooth-edged bokeh in a physical lens by inserting an apodisation filter inside: http://www.4photos.de/camera-diy/Apodization-Filter.html http://www.4photos.de/camera-diy/Apodization-Filter.html This is an aperture with fuzzy soft edges so that the bokeh fades out smoothly around the edges instead of being formed of hard circles. It makes the images look like they have Photoshop- or cellphone-faked bokeh, because you end up with effectively a Gaussian blur in the background.
