Thanks Pag, while I was taking sunset pictures a GBH landed in a tree behind me, I put the 150-600 back on and got this shot.

I took my grandson fishing there the next night and just as it was getting dark about 10 GBH started landing in the trees all around us 1 or 2 at a time. Most amazing thing I've seen. Too dark for getting any shots and since I had apparently stumbled onto their rest haven, I probably wouldn't have tried anyway. We tried to sneak away as best we could.
Tell yeh what mate - there is nothing wrong with the 7d focus getting lock on's like this and what i am getting with mine, my hobby is aviation -bet you couldn't tell anyway the other day i shot 165 airways shots of aircraft at roughly 5 miles up, and do you know i only got 2 that where out of focus because they were just to far away, that to me is Amazing
