**Read all about it Cloth dipped in warm water has removed the marks** Phew!
Hi guys
I was just cleaning the front element of my 70-200 ii in preparation for going to shoot tomorrow when I noticed a couple of distinct oval marks (rings). There are couple of very faint ones too. So I gave a rub with the lens cleaning cloth, thinking it might just be water splash residue from somewhere. It made no difference, so I got some lens cleaning fluid onto the cloth and tried again. Still there. It seems the marks might be on the inside, but its difficult to tell. If they are on the outside, no amount of cleaning will remove them, so is it a problem with the coating maybe?
Has anyone seen this before or have an idea what might have caused this? It makes no difference to the files, but if it gets worse, it probably will. I'm sure the marks weren't there a couple of weeks ago. The marks can be seen in the highlighted rectangle. Sorry for the link, but please click HERE to view. I did post this on another forum, but maybe someone here will have a few different thoughts
**edit**
I just did another shot HERE Its looking like a coating problem to me.
