I stand corrected, Daan - just tried it and both lenses do give an
image without extension tube. The built-in extension of these lenses
is longer than I thought.
I have the impression that the image is less sharp in the corners when
mounted immediately to the camera. Could that be the reason that
Olympus only mentions their use with bellows or auto-tube?
