Ohhh thanks Fergul , rub it in a bit more why don't you
BTW Gary (aka Granite) has been kind enough to have a look at a couple of the rejected photo's from the 300 mm and he also thought there may be a problem with the lens being soft. Also it seems to produce some strange digital banding as well ....
Im still waiting for a good sunny day so i can do some tests on the lens. Then failing that i have already spoken to Canon and they have told me to bring it down to Elstree to have some test done on it. They will then check if there is a problems.It may take 28 Days though
The only good point about the whole thing is the fact that its under warranty , so at least it won't cost me a penny to get it checked
