Not true, there is no set pattern of L vs. non L to where the rings are. 75-300 focus at front 35-135 focus at rear ----------------- Hi Jim, Point taken. I'll clarify a bit further. All the mid range zooms that Canon make (i.e. ring USM types) have zoom rings at the front and focusing at the rear. You're correct about the 75-300. All of the entry level zooms (micro motor USM or MM/AFD) have a rear zoom ring and most have a next to useless focus ring at the front. Admittedly the mid range focusing rings are no wider than the entry level ones, but their positioning makes them more usable IMO. All of the L series zooms (2 ring) zooms have a nice wide zoom ring at the rear and a nice wide (usable) focusing ring at the front... I currently own none of the consumer lenses, so that slipped my mind. However there is still a pattern to Canon's madness! My point was that Canon are not consistent in the placement (and style) of the focus and zoom rings *across their entire range*, which I find a bit annoying - at least as much so as having the direction of rotation reversed. I guess if anyone finds the different locations of the two rings is not confusing, then the different direction of rotation probably won't make too much difference either....
