Lens internal part falling off? its a refurb lens

[cellomaster27]

Hello!

This is my 85mm 1.8 lens that I bought from Canon as a refurb lens. It's still under warranty but I wanted to ask you folks if this is something off the internals. I have never opened up a lens so I have no idea.. Basically, I was doing a family photosession and after the shoot, I noticed that a black strand was showing from the side of the lens. I just shook the lens and twisted the focus ring a few times and there it is. I would be shocked if that came from the outer environment as I take very good care of my lenses. I have not had any issues with refurb lenses so far and so this is disappointing. Especially since I have not had this lens for more than 6 months now. Would you guys recommend opening and cleaning it myself? Maybe its an easy fix? Thank you!

If the fragment is inside the glass you should certainly return it for a warranty repair; I can't imagine they would have an issue with that.

You got a one year warranty, same as new.

My guess is that some piece of plastic didn't get trimmed perfectly cleanly, and the little bit of excess plastic sheared off the first time it rubbed against something. Eventually, that ended up falling in just the right way to get out of wherever it was trapped, and it ended up between lens elements.

Depending on which elements, and depending on how that particular lens is designed, it could be an easy fix or a hard fix. I'd definitely let Canon take care of it. With that said, once they blow the plastic string out, I'd expect the lens to be fine.

It looks like a shaving from a drill. make sure its not on the rear of the lens. Canon drills a small indentation and puts a red paint dot in it for refurbs, at least many of them. A shaving could have ended up on the rear element. That's not likely, but check anyway.

I always assumed they did that with the mount removed ...

Thank you all! I just sent the lens today to the service center in costa mesa, ca. I didn't want to part with it but it needs to be fixed.

The "string of plastic" or whatever it is was inbetween the lens elements. I managed to shake the lens to the point of getting it to the very sides of the lens. I could just use it but I rather get rid of the excess now. Definitely inside the lens. lol I know that much. ;D

I don't have to worry about return shipping since it's under warranty, correct?
