Had the objective since 2006 (costs 1,099) until today to a 30D in use (30,000 trips). After about 1.5 J dust and lint in the lens. Sent for cleaning. In 2010, then the stability has progressively abandoned the spirit. Also back dust and lint. Then in 2011 began with the problems Shutter (stuck). The problem has been getting worse and no longer works the lens. Also weak is the zoom mechanism. Depends the lens down then it moves gradually from alone. Extended significant game in the bearings. Unfortunately, the lens in my view, mechanical weaknesses. Visually I can only praise it - has always delivered great pictures. But for the money I would not buy me today. Hoping for an improved successor with 2,8er panel.
