I think a lot of photographers obsess over silly stuff when they should be more concerned with impactful photographs.
That said, the bokeh on some of those old lenses was pretty cool.
I haven't tried this in a while but did you know that if you paste little stars in your lens or any shapes for that matter, your bokeh will then be that shape.
I confess that sometimes I do run across a picture that looks pretty cool and the lens adds something, I agree.
