Lost my lens hood :( ....

I lost the lens hood for 85L while I was doing an event.. are those aftermarket lens hoods for 85L any good? because I don't want to spend a fortune on a proper hood if the aftermarket can do the job (i.e. strong enough to protect the front from bumps etc. during events).

Yes go to Ebay and buy a replacement hood for 1/4 of what the Canon hood costs.

For that one, I'd probably go with the Canon one. It might reject the after market copy, and then you'd be in a real mess, organ rejection can be ugly.

On a lens of that magnitude I think I would opt for the Canon but if I was to try an after market I would maybe try this one: For $5 you can't go wrong. http://www.amazon.com …1&keywords=Cano​n+ES-79+II

i've not been disappointed with chinese knockoffs and usually buy 2 at a time at that price.
