Green-yellow ring on front element (X100)

[kevin_v]

Hey everyone. I've been using the X100 for a few weeks now, and it been working great. However, I've noticed a thin green-yellow ring around what appears to be the second frontmost lens element. I haven't noticed any IQ problems, but it's been bothering me. Is this normal? / Has anyone else noticed this?

I don't see anything like that on mine.

Eh? Can you post a picture of it?

Here's a shot of it (attached). [Please excuse the crappy cellphone shot; the X100's the only proper digital camera I have.]

Mine has that same thin green ring, looks like it is just a normal part of the assembly. Nothing to worry about.

[bhop73]

Oh, I guess mine does have it to, but you can only see it at an extreme angle like your pic.

Most likely the edge of the inner element. Nothing to see here.

Either the edge of an inner element, or one of the many coatings they typically put on lens elements
