But when you use such a lens for macro subjects you get a telephoto effect 
in terms of a very reduced depth of field, a condition where bokeh can 
play an important part in an image.

I was very surprised, to say the least, when I discovered the 50/2 had 
only six blades forming it's aperture.  None the less a great lens for 
landscapes ;-)
