Fabulous bokeh. I love it.
Here's a look at how the glass looks on its own.
As you can probably tell, it looks extremely small once mounted as compared to other lenses, but don't let that fool you. Finding the right position in the bag proved to be quite difficult as the protruding lens (though small) always found itself in awkward positions due to the unbalance of the body/lens. The 20mm + GF1 is still a better choice for portability.
