Hi, I’ve received my Canon R5 with the RF 70-200 f2.8 L IS. I think they are both great, but the thing is that the 70-200 came with a speck of dust attached to the front element (inside the lens of course, very noticeable). There is no sign of it in any photo at any aperture. What should I do? A part of me is saying: Enjoy and do take some pictures! The other part says return it!

I live in Argentina, so send the lens back is possible but a pain (big one).

Thoughts?
Thank you all
Agustín

Depends on how much the thought of it bothers you, I would say. It won't degrade your images, although resale value will likely take a hit while that spec is in there.
A great read on the subject: https://www.lensrentals.com/blog/2019/04/removing-fly-from-weather-sealed-canon-70-200mm/
" Takeaway message: if your dust spec is smaller than a fly (about 4mm by 1.5mm) it’s not showing up in your images. "

I had a speck of dust behind the front element of an EF 70-200mm f/2.8L IS USM mkII, and my experience confirms what Joules wrote - it makes no difference.

As for resale value, I have my doubts. I'm sure some people might try to leverage the dust speck to lower price, but there are photographers who understand it doesn't matter. I suggest trying to estimate how much it would hurt the resale value, e.g. asking a store that buys & sells used lenses, then decide how much effort you want to put into it.

Did you enhance the speck?

I think the misunderstanding is related to an idiomatic issue. I am not native in english, so that's why I did not catch the meaning of your question. Thanks anyway!
I am a native speaker, and I have no idea what YuengLinger means either. What I do know is that some folks try very hard to show how clever they are, rather than be helpful.

Personally, I do not think that is a speck of dust. It looks like something more solid and lighter in color than dust. I would return it.

Thanks Czardoom for your answer. i think like you, the speck seems more like a golden pice of metal. I will send it back.

I agree with you about this being something other than a piece of dust. But I can't believe you don't understand a simple question. If the OP didn't understand because of language difficulties, I apologize.

And what I do know is that, for some bizarre reason, people randomly post things here that seem to be meant to confuse, exaggerate, and exasperate. I took the OP as sincere until he acted as if he didn't know what I meant by enhancing the important part of an image. Again, I'm sorry for that.

I merely wanted to know if he had done something with processing to make the dust more apparent, because, as you say, it doesn't look like dust as shown. Clever boy. ;)

If it looks that bright, that glaring, that large, I'd return it immediately. From the image it looks to me like a chip in the front element or a flaw in the coating. Or a tiny piece of rice somebody dropped on it after lunch, maybe not putting their face mask back on before returning to the assembly line.

Other people replying here might not have taken a good look at this "dust"?

Lenses get dust in them, its impossible to keep it out. However, if it bothers you, return the lens or ask Canon to clean it. I suspect that being in Argentina might make those options expensive, but you can explore them. It won't affect any images but I understand, just seeing it every time can bother some people.

What he shows in the photo does not look like any dust I've seen. It really looks like he used a local adjustment brush to highlight the "dust," which is why I asked and had a misunderstanding. Could that be a drop of paint or something else that just got stuck there during assembly?

Thank you all for your answers. A technician saw the lens today and determined that the "dust" is in fact a part of something that got stuck there during assembly. Is in Canon's hands now. Wish me luck!

I am so glad to hear that Canon was responsive and willing to make it right. Good news for you and all the rest with these lenses!
