it's bean a while and after much deliburation and aboout a year ago brain ache
.
i sold the 40d and traded in the bigma 350d and ef 70-300.
as i struggled so much with BIF with focus aquring lock on and lossing the center oint on many lost bird images.
it was getting to my head so much i actualy gave for a bit but now im sorted d300 and the bigmos.
trying to du starling with the 40d was
but now with centre point and 20 little helpers i can get shots like this .
hope i haven affened any body in the canon group being a nikon user 
as you can imagen im a happy chappy
hope to post some very pleasing 600mm scope shots .
cheers j
