There was a thread a while back about this, with a link to an outside page which suggests it is possible to use the EW-83D II hood (spec for 24 1.4L) on the 16- 35 2.8L. Link http://www.photo.net/bboard/q-and-a-fetch-msg?msg_id=007emc A user here said it doesn't work. I'd like to know if anybody refutes that. I would like to use the narrower hood for the size advantage, and also for better flare and physical protection. Anybody doing it? Cheers.
