Hello!

I recently bought a used Canon 17-40L lens and noticed it has some white spots in the front element.

The spots seem to be in the plastic but don't affect the image.

I found this disassembly guide with someone with similar spots on the lens.

Any information would be appreciated.

The lens was $340 so it seemed to be a good deal, the lens is in perfect condition and has a UB date code.

Thanks,

Daniel

White dots with macro lens

that looks like water droplets that got molded and dried up! amazing how those droplets are in a row with almost equal space between them!
