I acquired my new goal in 2009 on eBay (fortunately because I had paid 350euros instead of 700 and some normal). He accompanied me during multiple trips in and worked very well until the end of last year, when he crashed when he was in zoom position. Unable to unlock it. I sent for repairs, which cost me 160 euros (plus collateral), without any other explanation that it came from a dust. 9 months again later, when I was traveling, it began to be weird, he no longer took stock of what I wanted to photograph, then I read on my case "ERROR 80", which completely crashes my case (forced switch off, remove and reinsert the battery, then back). According to Canon, it comes much of the objective, therefore, obliged to leave under repair, I will not do, it starts well enough. I liked him, but I think therefore I am going to change this, for what? I do not know yet ... Also I hear that some plastic thing wanders inside the goal ... there really is a quality defect that appears in time!
