Hi I have a problem with my canon 100-400L lens. One of the plastic ring inside got loose. Thats the first ring with "steps" you see looking in to the front glass, also front glas got dirty from inside, not a lot just a little bit its a some kind of lubricant or glue whatever was under the ring I think... anyone can help me with repair service ?? anything... I really don't wanna spend money on the new lens, this one is fine when I shake a bit and when I place that ringe wqhen should be works fine...
I would prefer the "send in" service...
