The Zoom runs counter-intuitive. The barrel extends at the wide end and shrinks at the tele end.
I'm using this on a SD14. So, I find the wide end not quite wide enough most of the time. I usually only bring this behemouth out when I need a fast aperture. Otherwise, it's heavy, big, and takes FREAKIN' HUGE filters.
The zoom and focus rings work really well. I like how the focus ring slides back and forth to engage or disengage the auto focus motor.

It was purchased before all the different OS versions came out. Wish I had one of those instead.
This one is can produce really nice shots. Typically I have to stay a least one stop away from the largest available, and usually try not to get all the way extended at the 200 mark to get better results.
I still really enjoy this lens. It has worked very well for me over the years.
