Hello. I've just bought the S2 together with the 1,4/50 and the 2,8/28 lenses. I have a question about the apperture on the distagon 28. Is it not supposed to be hidden totaly when apperture 2,8 is choosen? For me it is visible, rather much. And also, there seems to be no difference in apperture size between f16 and f22. That is, there is equal ammounts of light through apperture 16 and 22. Is there anyone with any idea of what could be wrong?
