A friend took a picture of me and while he was rewinding I noticed the shutter leafs opening again. Of the five leafs in my 80mm CB lens 3 have bent tips. Th etop one has a tip that bends out slightly wich seems logic but the one across wich is bent slightly downwards is not the bottom one so the bottom one will be bent down in return. I hope three of the tips are supposed to be bent. But it doesn't look natural and I've never seen it before.

Please tell me it's okay since I just bought the lens used and I don't have another lens to compare. Yoy can check it after you have taken a picture than look in the lens while rewinding, at the end of the rewinding the shutter will start to open this is when you can see all the leafs when half opened.
