It's for sale here in my country. Prize is around u$s1100. I think i could get it down to u$s800. Do you think those marks will degrade the image quality? Coming from a 24-105mm (10/10 conditions) do you think the upgrade worth it?

This seems to me a kind of "peeling" of the coating on the front element, and there was a segment on Canonrumors about such thing in the 24-70 F2.8II.

At the time, the user quashed about the cost of replacing the front element, but did not seem to affect the image quality.
However, any "lack" in the coating makes the lens more prone to flare if some light hits the front element at a certain angle.

Not unless I tried the lens and found no affect on the image quality.

And even then - no.

I would buy it, but for $ 500, and not a cent more.
A lens in this condition does not have any resale value, should you ever want to replace it in the future.
For about $700, you might get a brand-new 24/70 f.4!

The front element is known for peeling of the lens coating, and, as I recall, its very expensive to fix. It is certain to cause issues in photos with bright lights, because the area of the lens will not reflect the bright lights as it should.

Check with Canon or a repair station about the cost to replace the front element. The cost to repair it could drive the price to higher than the cost of a new one.
