Hi!
Recently I purchased EOS 70D with kit lens (EF-S 18-55 STM) and tele-zoom (EF-S 55-250 STM). Both lenses give excellent result for still photos.
But while video shooting, I notice considerable jerk in the video due to adjustment in the zoom ring of the lenses. Less noticeable nuissance in the video if I make sudden turn of the zoom ring but very much noticeable while making slow & gradual shift on the zoom ring. As if shot by wobbly/shaky videographer! Thus an inferior video result in comparison to cheaper cameras that have TELE / WIDE zoom buttons. As such the zoom ring appear to be quite free to rotate & no mechanical defect on the lens body.
Any suggestioins please?
