Hi all,


I recently sent my 10-22 to Canon as I noticed that it had picked up a small foreign object just under the front element. They repaired it promptly, but it did cost me $95.


Now, I recently noticed that my 17-40 has picked up a couple of very small particles (they seem close to the surface too) and my 70-200 f4 IS has also picked a quite large object too (it seems to be round the middle of the lens).


I don't really bash my lenses much and I have to say this is getting annoying. Is this normal? Do you also find that your lenses easily pick up foreign objects? And aren't those L lenses suppoesed to be weather sealed?
