A couple of weeks ago I assembled a stack of "normal" lenses, adapters and
an E-P1 to shoot a comparison to see how each lens rendered the scene I had
set up. The lenses ranged in focal length from 45mm to 58mm and included a
few zooms set at 50mm. This link:
http://lrh.structuregraphs.com/test/lens_02_f22.htm shows the setup which I
hoped would help to differentiate the rendering of the different lenses, in
particular bokeh. Note the elements which normally show up bad bokeh:
sticks, specular reflections (aluminium foil on a stick, candelabra against
the wall), striped wallpaper. I used a 500W photoflood for lighting,
tungsten WB on the E-P1, ISO 400, aperture priority mode. The images were
only resized to 450x600 for the web with no other post processing. Note
that the E-P1 doesn't maintain consistent exposure when the lens is stopped
down.
The comparison page is here:

Any comments welcome, in particular I'd like to know which lens you think
has the best rendition of the subject.
Also let me know if you find broken links or any other problems.
