I have a Chinon 300mm f5.6 (looks like a very early Tamron with tapered body) with M42 mount on it's way to me with the aperture blades stuck wide open. I am assuming it is because of oil ingress. Are the blades easy to access? Is it just a matter of removing the four mount screws? _________________ "I've got a Nikon camera, I like to take a photograph" - Paul Simon |
