I went through this on mine. Get it serviced, once they are serviced right by a technician, the cameras perform beautifully. I think they just don't always come out of production perfectly. The place I would recommend (I've used them twice and they are exceptional for Canons - it's all they service) is: [http://www.CamerasAndParts.com|www.CamerasAndParts.com] They are very affordable as they have flat rate service packages, their work is superb. Never had a problem with either camera after service, they do some tweaks to make them better than the way they come from production. I would really recommend them if you need help with this lens error problem.
