Look at the diaphragm blades, is there any oil on them? There shouldn't be. The diaphragm has to close very quickly when the camera takes a picture. Set the aperture ring to F22. Push and release the diaphragm lever, how long did it take to close? If there's oil on the blades a good camera repair shop will clean them. I payed 17 Euros to have an F SMC 50mm F1.7 cleaned, it's now as good as new.
