>The DC lens lets you melt the background into beautiful bokeh even when it's stopped down as far as f/8.
again, i'll posit that the focal length (and distance to bg) has the greater contribution there. here's one at f/6.7. i think the DC has a more subtle effect than people realize when it comes to bokeh - that being said, i still have the 135mm on my bhphoto and amazon wishlists. i would really like to fuck with it for a bit. i'll probably end up renting one for a shoot trade-out.
