isy At risk of appearing rude ... it's interesting how we as photographers can afford such lenses yet can't afford lens caps ;o) Canon's hood for the 20mm *is* expensive BUT it also works. Any circular rubber hood will do one of two things 1) it won't vignette - therefore it won't be any where near as efficient as a "vertical" lens hood as it could be 2) it will vignette big time. I've tried adding masking tape around mine (EOS 1n, 100% viewfinder) and any more than about 1mm beyond the shape of Canon's hood comes in to the frame. It reall is a case of get the real thing for this lens, sorry.
