Your lens is defected , this is not a normal behavior, need to open your lens and fix things inside. Be careful with usage , before you make more damage on blades!

Yip seems to be sticky appertue blades will have to do some surgery.
Damn the lens still looks like new.
The only thing ive noticed is the pin at the back has been forced and peened into the housing could this be a problem??

Forced pin not good at all, I don't it is related to or not. If you have repair man around I suggest to bring there this lens is a valuable lens today it's price fetch around 400 USD don't risk it's safety with DIY repair.
