I see nothing in those pictures that would indicate there is a scratch on the lens. I would just relax and go take some pictures if I was you.

I have an old lens that has a chunk missing from the front element. The effect is not noticeable in the images it makes.

It probably reduces the image contrast slightly and could make it more prone to flare but I've not seen this though I must admit I hardly ever use the lens.

Any significant scratch should be very easy to spot if you shine a light into the lens. I believe problems with the rear elements have more of an affect on images formed..

Yeah . . . Not only is scratched, but I can see lots of haze and even some degree of actual element separation.

But . . . since I'm such a nice guy . . . I'd give ya' twenty bucks for it anyway. ;-)

what makes you think it's scratched? looks fine in photos.

What they said - there's nothing wrong with it, it looks completely fine. You can see it from several angles with the light hitting it and there are no scratches on the front element.

Are you seeing something specific that makes you think it's scratched??

There is nothing specific I see but i am worried that i had cleaned the lens wrong, or that the lens what not is as good as the condition that the seller was describing. Maybe i am just paranoid? Who knows?

Make sure you're not seeing the room lights reflected around. With all the glass elements inside a lens, it can bounce lights around in all sorts of weird ways and it looks for all the world like a spot or dust on a lens. Make absolutely sure the spot you see doesn't move or disappear if you change your position to the light :smile:

And even for all that, don't worry about tiny spots, they're highly unlikely to affect photos. Unless you've got a chip in the glass or serious gouge (which you don't, judging by the photos) it's unlikely you'd ever notice it in the output.

ok thanks. So i guess i am just overreacting. It mostly like is perfectly fine. by the way, those spots i see appear on all of my lenses that don't have a filter. They appear on my nikon legacy and my kit lens. It must be something normal? I don't know.
