Well known phenomenon, have read all the other reviews. I actually thought Canon would have solved the problem, but mine showed dust in just a few days, while I was wating for my protection filter to arrive.
I wonder if there is anyone who can confirm that putting on a filter will do to prevend further dust to appear ?? And if Canon cleans it, can they solve the problem ?
It annoys me, but I have to be honest that it may not be visible on photos. But I just cannot understand this flaw appearing in a lens in this price class.
Canon told me they're familiar with the problem, but it has not reached the 'status' of a construction error at this point. It guess it hurts to admit this (with financial consequences).
Perhaps someone can give me advice how to address the
