<snip> Absolutely! For example for the 16-35L, 17-35L & 17-40L lenses you can uses the hood for the EF 24 f1.4L (the EW-83DII). It's both narrower *and* deeper than the standard hoods and causes no vignetting on a 10D. I'm pretty sure it works on the 20-35 f3.5-4.5 USM (non L) as well. For some of the primes you simply move up to the next hood in the range. The 28 f2.8 and 35 f2 use the EW-65 (various versions) for full frame, but work with the ES-65 hood designed for the Mk 1 50mm. The 50 Mk1 uses the ET-65 hoods designed for the 85f1.8/100f2 pair.
