The Zuiko 50mm is a funny one, it always apeared to me to be designed to be used with the EX-25 extension tube.

without it it is supposed to make a great portrait lens, pin sharp with great bokeh.

One thing I don't understand in the review is why Olympus in camera processing makes the lens sharper? Surely the sharpness is measure independently of the camera? Also, all digital cameras process the image don't they?
