I don't really know. Perhaps, because the f:2 focusses closer than the 3.5, more markings are crammed into the same space? I never had the two at one time to compare; besides I rarely look at the scales. Your "K" version - I think yours has a rubber insert on the focussing ring - should be basically the same as mine, a pre-ai with factory ai conversion.
