You'd have to remove the front element, in that case. Try it out before doing anything, many front element scratches don't show up at all. _________________ Dave - Moderator

I'd do as Dave suggests, and try using the lens first.

Yup, also check this out.
I just got an Nikkor Micro 55/2.8 for about 100EUR which was near perfect, but with a miniscule hairline scratch on the rear element that you can see only by looking at it in the right angle. Rear element damage is usually worse than front element damage, but at least I can't see any loss in IQ.
I'm with Attila here - it's silly how people panic and go crazy over really minor damage. It affects the resale value, but if you sell it to a good home, ie. to someone who's knows what the lens can do and what it's worth, you can still get a good price for it. _________________ Lars

for me it doesn't look like a scratch! and even it would be one, i am with the previous speakers. such a tiny scratch has no impact on IQ. you will find no human eye that detects a scratch of that size (or even bigger ones) in the final image.

Yeah, that looks like some sort of foreign object inside the lens. Is the second object shown in the photo a shadow or reflection?
+2 or 3 or whatever about scratches. I own a Nikkor 28mm f/2.8 that would have a low value because of a couple of scratches on the front element. But they make absolutely no difference in the photos. Years ago, I bought a Nikkor 180mm f/2.8 ED that actually had a chip out of the front element. Got it for a great price as a result. That lens was one of the sharpest, contrastiest lenses I've ever owned.
If it's really bugging you, dismantle the lens and remove it. Otherwise, fuggedaboudit! _________________ Michael

Yes, it is an Object. Part of the lacquer layer in black, which acts as a
absorber in the inner layer between the glasses. Not more.
Dont worry about..
Here is a pic, which shows a more bad situation on a 2/35mm Leica Summicron.. cause of the existing fungus. But you can see nearly the same object. Was a part of the lacquer layer. Looks like yours.
Did clean the Summicron and remove the fungus as well as the object.
