Before this latest leak, I assumed it would be fixed aperture and fixed focus to make it as simple and as cheap as possible. I also didn't imagine that olympus would ever make another manual focus lens.

Since they're going with a 3-click manual focus, why not add 2-click aperture as well (f/4 and f/8)? Just sayin'...

I think it's either or, if you want to make it cheap. A cheap (blade-less) aperture could be made by simply having a disk with different sized holes slide, but that won't work easily in a focusable (moving) lens.
