Dust in lens and resale value

I was getting ready to post my 15-85 for sale and taking pictures of it when I noticed it has some dust that is visible when looking through the front of the lens. It's really small specks and only can be seen in the right light. It is not showing up in photos as far as I can tell.

Is this going to kill the price I'd get for selling it used? Just wondering if it's even worth it now. I don't want to take $100 less than the going rate for a few specks of dust. If that's the case I'll just keep it. Or do people just steer completely around lenses with dust? It seems most would have some sort of dust if not sealed and looked at in the right light.

I've never owned an EOS lens that didn't have some dust in it. Perhaps some people don't look close enought to notice it, but any reasonable buyer has got to realize that there is some dust in every one of these lenses.

I've sold a lot of EOS lenses. If the dust is small and just a few specks, it won't be a big deal.

While i agree with what JeffreyG said, what would you do/think if you were buying it? You can choose to let that be your guide, or not.

Wouldn't say kill but I'd personally value it a little less depending on how much dust there is. Just make sure you note it when selling it.

I wouldn't let it affect my buying decision because I know it does not affect the image. My 17-55 and 28-105 both acquired internal dust in their first year of service; telescoping zooms are prone to this because of the air they suck in when they extend. It would only bother me if the seller didn't disclose it and give me the option to consider it.

Do most people just not disclose it then and surprise the buyers who notice it later? I definitely would feel guilty for not disclosing it.

I was thinking of going a bit less than the going rate

I think each dust you have you get $50 less....

Just kidding....

However, you can't tell me you would try to haggle over the price just because it got couple of dust inside??? If I were the seller, I would put your in my ignore list...

Oh and what kind of picture can I take to show the dust is not visible?

You guys all just have to realize that there are two kinds of EOS lenses for sale:

Ones with dust in them that the seller has noticed and disclosed.

Ones with dust in them that the seller has not noticed or disclosed.

Look, the dust will never show up regardless if you stop down to f22. I am not taking about sensor dust. If you are afraid of dust, don't use the lens.

I was just preparing for the people interested demanding pix showing the dust isn't visible.

Most understand that lenses acquire dust and rarely have any impact on image quality. State that there is some dust and has no impact. Should not be an issue.

I was researching dust in lenses for a possible purchase when I found this link:

Show him this if there is concern I really don't think a little dust makes much difference.

Stop down as narrow as you can, shoot against a white wall or light-blue sky; that should show any dust specks.
