Re: Source of flare?

Hi

i have been out of the country an unable to update. The opening on the lens hood has been closed-but good thing to note so thanks. As I commented on the previous post showing the same issue, the problem has been escalated at Canon. The senior technician now working on this certainly acknowledges the issue and has dismissed the previous “dirty lens” theory. He has not seen it before and first thoughts are possibly the filter. But I have also now sent over the link to the bird photos posted by Abbott - thanks for those-showing the same issue, with no filter on the lens, and occurring at a different focal length. It is an inconsistent issue to reproduce but trying to narrow it down. Thanks for all the interesting comments and apologies for the delay. I was not expecting to travel.
