Loose element on 85mm f/1.8?

I love my 85 1.8 to death (as seems to be common among those of us who own such lens) but it seems to have a loose element at the moment. Here are two 100% crop sections of a photo taken yesterday - one near the center of the image and one towards the right side. As you can see, the chroma seems to be pretty pronounced and it seems weirdly soft in a few places.

Something inside it also seems to shift when it moves around.

What do you think?

It's really hard to tell with the type of subject you are using. There are too many objects in front and behind the plane of focus. We could possibly see more if the subject was more in the same plane. Maybe a brick wall? The noise you are hearing could be the blades of the aperature and this is normal.
