Douglas, is yours creeping on the Tight setting? Or only on Smooth?


On Smooth setting. As soon as I turn the lens vertically, it creeps from 400mm to 100mm in about 6 seconds, you can watch the zoom ring turn. I just tried the Tight setting for the first time few minutes ago, kind of too tight. I think I will stick with the Smooth setting. I have used the lens to shoot some flowers and planes, it didn't seem to bother me but I didn't hang the lens vertically much though.


My friend's copy takes only 2s to go 400 to 100 (he sent me a short video). I haven't timed mine yet but I think maybe 3-4s.

There is so much variability. This would also correlate into how you feel yours is too tight on tight where as I feel mine is okay to use on Tight.

EDIT: Mine is taking 5-6s. It just takes a second to really start creeping. Looking at my friends video his maybe more like 3-4s as I can’t tell when he lets go and if I has a slow start then it may be longer than 2s. But it is only 2s once it starts to move. Certainly looser than mine.
