I currently have the EF16-35mm 2.8L. Thank you for the information on the Circular Polarizer...


If you have the 16-35/2.8L original version or "Mark I", it uses 77mm filters (which also will fit your other two lenses... the 16-35/4L IS, 17-40/4L too ).

 

If you have the 16-35/2.8L Mark II, it uses 82mm filters (only slighlty bigger, but they tend to be a lot more expensive).

If you haven't purchased filters yet you can get an 82mm and the 82-77 stepdown rings and thus only buy one specialty filter for use on all lenses.

For a stepdown ring to work effectively, the filter has to be too big for the lens by enough to ensure that the depth of the ring doesn't push the edge of the filter into the field of view (which is wider, the farther out you get from the front end of the lens). Since there's not much difference between 77mm and 82mm, you'd have to satisfy yourself that it couldn't happen in this case, i.e. that you don't need a filter even bigger than 82mm.
