Hi guys

Just bought an Xpan 30mm lens (bargain condition) from Keh.com and delivery arrived today.

When I inspected the lens, I found some silver particles inside the lens, probably on the second or third element. I took it to a repairer which is close to where I work, and he suggested that this is paint chips inside the lens and he's not sure whether he can fix it. He said that some lenses require a repaint and that's all is needed but some lenses are more difficult. He suggested me to return it to Keh, although he thinks that it will not affect the image quality

What do you guys think? Have you every experienced this problem with Xpan 30mm or any other lenses before?

Thanks for an input!
