Fantastic video, thank you! Enabled me to (1) fix my sticky zoom (clutch material breaking down and jamming the slide) and (2) clean out dust from behind the outermost glass element. Idiot's tip - don't dismantle the clutch, just clean it (I spent an hour refitting around 200? 0.7mm? bearings into the clutch).
hi siauliutv in my 28-300 it no longer brakes the stroke between SMOOTH and TIGHT practically the seal is worn! if I remove it, with what do you advise me to restore the clutch? I thank you so much
