The aperture ring still turns same way as a current lens for max and min. From a photo one would think at first that it worked the opposite way to normal, but because if the switching of the scales between moving and static it doesn't. It's obvious with a lens in the hand ! Mike > From: Hans Pahlen > In James Lager's book on lenses (page 202), there are pictures of both > Summicron 90 versions.
