Just purchased one used and looks to be in decent condition. However, I’m confused about the focus ring. All the reviews praise this lens for the high build quality and this focus ring feels quite poor to me. I can feel a constant light mechanical “clicking“ or “stuttering” at seemingly random times, and it intermittently makes a faint plastic-sliding-on-metal sound. It just doesn’t feel “right”. (The lens having power or not makes no difference.) Is this normal? Should I send it back? I use manual focus consistently with my lenses, so I can see this becoming irritating...
