I don't own any L glass (or even an SLR for that matter) but given the price I would be seriously disappointed with comments like this.
Surely it should focus were you want it and whilst almost any lens will be sharper stopped down "a bit", to have to go to +f10 on an f4 lens seems to be giving away a lot of light.
Is this really a normal expectation of Canon's flagship glass ??
