Strange Blurring of Subject with 70-200 f4 IS (Link to Image)

Hi guys,

I took a test shot with my 7D using a 70-200 IS f4 which I have owned for a couple of years

and came up with this strange blurring.  http://smu.gs/Sro6Ok  I took the 70-200 off and put the 24-105 lens on and it was fine.  Swapped back over with the 70-200 and it's good again!

I don't know if it was dirty contacts.?  Don't think so..  Has anyone got any ideas?

Thanks guys..
