Question about Canon EF-S 17-85MM F/4-5.6 IS USM Lens
When the lens is on the camera pointing downwards the lens zoom ring slips and extends on its own. Is there any way of tightening this up?
Yes, this happens even when the lens is brand new. Some other lenses have a Zoom lock to prevent it. What I did was to slip a flat rubber band around the black area just behind the zoom ring, the area where there is s white mark or line, with the band ring just touching the zoom ring. The rubber band should be fairly tight, but not too tight. When the zoom ring revolves, the rubber band touching it gives it just enough friction to prevent it from turning. You can adjust it to give as much friction as you want. Hope this helps. Jay
