I think if I remember that this is the same type of glass that Canon used in the 400mm f4 DO lens and there were a lot of complaints over odd things like your experencing with the 300mm.
I've also had a little go at your Carron Crow.
On my screen that looks good.
Can I send you all my images?
At this stage I am just checking the camera / lens performance and using the iPad for convenience. I am even shooting jpeg at the moment while I find my feet.
