100mm 2.8 Macro Not focusing

My macro lens is constantly hunting for a focal point. It has recently started this and no matter if I'm using it for ring shots or portraits, good lighting or bad, it won't focus.

It's never been dropped or damaged. I've had it for almost 5 years.

I doubt that. My experience is that posting in this forum doesn't generate email traffic for the poster. A poster's email address isn't even made readily available.


???  It's called subscriptions. 

 

You can subscribe to email alerts whenever someone replies to thread you've replied to.  You can set it up so that every thread you reply to is automatically subscribed, or not.  Check the "Topic Options" tab at the top of the thread.

Yeah, I guess I've had threads set up that way in the past, but I'm not sure I have any set up that way now.

 

But I think we're starting to get wrapped around the axle over a non-issue. Yeah, the current poster replied to an old thread because the symptoms looked similar. They probably weren't, but that's hardly the point. The mistake was easy to make because the messaging program makes no effort to warn you that you're replying to an old thread. Indeed, modern messaging systems appear to behave that way on purpose. Note that in this very thread the date on which a message was sent is displayed in a very light gray font that's intentionally hard to read. I don't know why they do that, but what I do know is that calling out a poster for not noticing that a thread is stale is arguably a form of blaming the victim.
