Return my 35 Summicron M ASPH?
I got this from KEH last week. It was EX+ condition. However, when I look at the front of the lens. It appears that there is a 'secondary' aperture blade 'stuck' open-in the widest position , in front of the actual aperture. It looks like I can see the points of this secondary aperture from the front of the lens. They do not show from the lens mount side, so they are not intruding on the image area, and the aperture clicks thru every stop accurately. Has anyone seen this before? Is it normal, or should I exchange it? Does anyone have a picture to post of the front of the 35 Summicron M ASPH?
