Whatever the information is, it can't be worse than the Nikon oil issue
Seriously though. Best way around it is if it appears somewhere else first. A bit like how CR often mentions stuff from Keith at Northlight.
Unless you are tied to Canon is some way I see no issue with this. Anyhoo, PDF up for an hour and it gets every where. Send it to the guys at Photography on the Net if you want exposure.
If the 70-200 MkII is in there I WILL want to know about it as I've had 2 AF barrels die on me within warranty. On two separate lenses.
