    I assume you had a lens hood on, you say you've cleaned the lens - both ends? Not condensation is it,

      David I have this lens also, I have found if shooting into the sun, it will/can produce sun spots.

          Just tried it indoors fine, looks like I have got to get a lens hood for it and try that.
          Thanks both.

            Before you shell out for it, it is rather expensive and also not very effective. Because it has to work at the 10mm end, it isn't much of a lens hood, so you might be better off keeping the money in your pocket and just remember not to point it towards the sun.

              That’s also a lens that I have David, I’ll give it a try.

                You could just hold your hand over the top of the lens, or fashion a bit of thin card or magazine. I agree with Colin, it's a paltry bit of plastic.

                  David if you really want a lens hood, try a google search - you can usually get an alternative to the genuine Canon version at a fraction of the cost.

                    Thanks Bill, I have ordered a cheap one just to see if it helps. Dave

                      I think you will still need to do as Bo suggests....because the hood is so wide (as Colin says) it will not block potential light causing flare unless at a very oblique angle...I had this lens too...and as with others you can block the light rays with your hand - takes a bit of trial and error.
